Answer:
The correct options are :
b. 5
e. 25
Step-by-step explanation:
The question is incomplete. The missing part is :
'' Which of these values will prove Sherry's claim is false :
a. 3
b. 5
c. 7
d. 11
e. 25 ''
One way to prove that Sherry's claim is false is finding one odd number greater than 1 that when we replace it in the denominator of the expression [tex]\frac{1}{x}[/tex] the result isn't equivalent to a repeating decimal.
Let's analyze each option :
a. 33 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{3}[/tex] ≅ 0.3333 (repeating decimal)
The option a. 3 won't prove that Sherry's claim is false.
b. 55 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{5}=0.2[/tex]
The result isn't a repeating decimal.
The option b. 5 will prove that Sherry's claim is false.
c. 77 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{7}[/tex] ≅ 0.1428 (repeating decimal)
The option c. 7 won't prove that Sherry's claim is false.
d. 1111 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{11}[/tex] ≅ 0.0909 (repeating decimal)
The option d. 11 won't prove that Sherry's claim is false.
e. 2525 is an odd number greater than 1 ⇒ If we replace in the expression [tex]\frac{1}{x}[/tex] ⇒
[tex]\frac{1}{25}[/tex] ≅ 0.04
The result isn't a repeating decimal
The option e. 25 will prove that Sherry's claim is false.

Happy Paws charges
$20.00 plus $4.00 per hour
to keep a dog during the day. Woof Watchers charges
$9.00 plus $5.00 per hour.
Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable x to represent the
number of hours.
Answer:
Happy paws
y = 20 + 4x
Woof watchers
y = 9 + 5x
x = 11 hours
Step-by-step explanation:
Let
Number of hours = x
Total cost = y
Total cost = fixed cost + variable cost
The equations are:
Happy paws
y = 20 + 4x
Woof watchers
y = 9 + 5x
solve the equation to find for how many hours the total cost of the services is equal.
Equate total cost of both services
20 + 4x = 9 + 5x
Collect like terms
20 - 9 = 5x - 4x
11 = x
x = 11 hours
Check:
Happy paws
y = 20 + 4x
= 20 + 4(11)
= 20 + 44
= 64
Woof watchers
y = 9 + 5x
= 9 + 5(11)
= 9 + 55
= 64
what are the coordinates for B
Answer:
(-0.5, 0)
Step-by-step explanation:
'B' lies on the x-axis. This means that it's y-value is zero.
'B' also is in between '-1' and '0'. This means that the x-value is -0.5.
'B' should be (-0.5, 0).
Hope this helps.

Let's add all the values on one side and make it equal to the sum of all the other values on the other side
(- X) + (- X) + (- X) + (- X) + (- X) + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 = X + X + X + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1)
- 5X + 12 = 3X - 8
- 5X - 3X = - 8 - 12
- 8X = - 20 x(- 1)
8X = 20
X = 20/8
X = 5/2or X = 2.5
Solve for x. 5+(x-2)=-8
Answer:
x = -11
Step-by-step explanation:
First, get rid of parentheses:
5 + x - 2 = -8
Then, simplify:
3 + x = -8
Finally, subtract 3 on both sides:
x = -11
Hope this helps ^^
Answer:
x = -11
Step-by-step explanation:
5+(x-2)=-8
3+x = -8
Subtract 3 from each side
3+x-3 = -8-3
x = -11
The outside of a rectangular picture frame measures 10 in. by 11 in. and has a 1-in. border. What is the area of the border?
Step-by-step explanation:
Area of the border = Length * Breadth
If the outside measures 10in by 11in with 1-in border, the length of the picture with border = 10+(1+1) * 11+(1+1)
Area of the border = 12*13
Area of the border = 156in²
Note that the border length will be added at both edges of the frames for each length and the width of the frame

[tex]\frac{3}{16}[/tex]
Step-by-step explanation:
We do the division first because of PEMDAS.
Apply the fraction division rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]
Therefore,
[tex]\frac{5}{8}-\frac{1}{4}\div \frac{4}{7}=\frac{5}{8}-\frac{1}{4}\times \frac{7}{4}[/tex]
Multiply the two fractions:
[tex]\frac{5}{8} -\frac{1\times \:7}{4\times \:4}[/tex]
[tex]\frac{5}{8}-\frac{7}{16}[/tex]
The LCM of the denominators (8 and 16) is 16.
Adjust fractions:
[tex]\frac{10}{16}-\frac{7}{16}[/tex]
Subtract:

The perimeter of a rectangle is 234 meters.
The rectangle is twice as long as it is wide.
What are its length and width?
I am going to show you how easy this is. Once you understand, you will be able to do this forever.
:
Assuming the side of the rectangle are (L) length and (W) width, the perimeter:
2L + 2W = 234
:
"the rectangle is twice as long as it is wide,", the equation for this statement:
L = 2W
:
In the first equation, we can replace L with 2W, then we have
2(2W) + 2W = 234
4W + 2W = 234
6W = 234
Divide both sides by 6
W = 234%2F6
W = 39 meters is the width
:
Remember it said the length is twice the width, therefore:
L = 2(39)
L = 78 meters is the length
:
:
Check this by finding the perimeter with these values
2(78) + 2(39) =
156 + 78 = 234
Tommy, Ali, and Jack each have a band. Tommy’s band has won three less awards then Ali. Jacks band has won twice as many bands as Tommy. They have a total of 23 awards. Find the number of awards each persons’ band has won.
Answer:
Tommy's band won 5 awards, Ali's band won 8 awards and Jack's band won 10 awards.
Step-by-step explanation:
Let the number of awards Tommy won be x.
Number of awards Ali won -> x+3
Number of awards Jack won -> 2x
[tex]x+x+3+2x=23[/tex]
[tex]4x+3=23[/tex]
Subtract 3 from both sides:
[tex]4x+3-3=23-3[/tex]
[tex]4x=20[/tex]
Divide both sides by 4:
[tex]\frac{4x}{4}=\frac{20}{4}[/tex]
[tex]x=5[/tex] (Tommy)
[tex]5+3=8[/tex] (Ali)
[tex]5\times2=10[/tex] (Jack)
Answer: Tommy won 5 awards. Ali won 8 awards. Jack won 10 awards.
Step-by-step explanation:
First give each person a variable:
Tommy = y
Ali = a
Jack = x
Then figure out the equations:
Tommy won 3 less awards than Ali, so the equation would be (y = a - 3).
Jack won twice as many awards as Tommy, so the equation would be (x = 2y)
All three won a total of 23, so that would be (23 = y + x + a)
Next, plug in (2y) into the (x) of (23 = y + x + a)
This would result in (23 = 3y + a)
Then you would plug in (a - 3) into (y)
This would result in (23 = 4a - 9)
Solve for a: (a = 8)
Now that you know (a = 8), plug that into the first equation (y = a - 3) to find (y).
Answer: (y = 5)
Use (y = 5) and plug it into the second equation (x = 2y) to find (x)
Answer: (x = 10)
Answers:
a = 8

Addition property of equality
Multiplication property of equality
Division property of equality
Write an equivalent expression( which means simplified)
Distributive property
Answer:
a: given
b: multiplication property of equality
c: distributive property
d: simplified
e: addition property of equality
f. division property of equality
Step-by-step explanation:
step a will always be given because it is starting equation. step b is multiplication property because everything is multiplied by two so you don't have to deal with decimals. step c is distributive because you distribute the -5s in the parentheses. step d is simplified because they combined like terms and nothing changed sides. step e is addition property because you added 5x to both sides. step f is division property because -7 is divided from each side.

(Select all that Apply) Which of the following is an equation?
5 - 4= 9
5+4= 9
9=9
5+4-9
To find:
Which of the following options is an equation.
Solution:
A mathematics or algebraic statement which represents that the values of two mathematical expressions are equal, is called an equation.
In option A,
[tex]5-4=9[/tex]
[tex]1\neq 9[/tex]
LHS≠RHS. So, it is not an equation.
In option B and C,
[tex]5+4=9[/tex]
[tex]9=9[/tex]
LHS=RHS. Both are equations.
In option D,
[tex]5+4-9[/tex]
This is an expression, not an equations.
Therefore, the correct options are B and C.
Mark is 5 years older than Juan, who is X year old. Write an expression for Mark's age.
Answer:
y = x+5 where y is Mark's age
Step-by-step explanation:
Hi there, to answer this problem, you need to really think about what it is asking. In saying that mark is 5 years older than Juan, we know it is going to involve addition. Then, you simply need to think about the relation to Juan's age. In this case, Mark is older so you add to it. Hope this helped!

2.3999
1dp) 2.4
2dp) 2.40

1 d.p:
4.03834 = 4.0
24.8845 = 24.9
0.62346 = 0.6
2.3999 = 2.4
The 1 d.p is the first number after the decimal point and to write it as 1 d.p you need to round it off.
2 d.p:
4. 03834 = 4.04
24.8845 = 24.88
0.62346 = 0.62
2.3999 = 2.40
The 2 d.p is the second number after the decimal point.
3 d.p:
4.03834 = 4.038
24.8845 = 24.885
0.62346 = 0.623
2.3999 = 2.400
The 3 d.p is the third number after the decimal point.
