which expression can be used to solve 3/5 ÷ 7/10
Answer:
Step-by-step explanation:
3/5 divided by 7/10
You use KCF
KCF stands for keep change flip
So it would be 3/5x10/7
3 10 15
_ x _ = _
5 7 7
you need to simplify it so the 5 in 3/5 would be a 1 and the 10 in 10/7 would be 5

Please help this sat math problem got me stumped
Answer:
option A
Step-by-step explanation:
[tex]3x-y=12\\ =>3x = 12+y\\=>x=\frac{y+12}{3}[/tex]
Putting the value of x in [tex]\frac{8^{x} }{2^{y} }[/tex] gives :-
[tex]\frac{8^\frac{y+12}{3} }{2^y} = \frac{2^3(\frac{y+12}{3} )}{2^y} = \frac{2^{y+12} }{2^y} = 2^{y+12-y}=2^{12}[/tex]

Tina made $121 this week for workkng 22 hours. How much will she make next week if she gets paid at the same rate but only works 14 hours?
Answer: she made 77 dollars
Step-by-step explanation:
121 divided by 22 is 5.5
5.5 will be her pay rate per hour
5.5 times 14 is 77
Answer:
77 dollars
Step-by-step explanation:
We can use ratios to solve
121 dollars x dollars
--------------- = --------------------
22 hours 14 hours
Using cross products
121 * 14 = 22x
Divide each side by 22
121 * 14/22 = x
77 =x
(5x+2) = 32 what is the value of x ?
Answer:
x=6
Step-by-step explanation:
5x+2=32
Step 1: Subtract 2 from both sides.
5x+2−2=32−2
5x=30
Step 2: Divide both sides by 5.
5x
5
=
30
5
x=6
Answer:
x = 6
Step-by-step explanation:
5x + 2 = 32
Subtract 2 from both sides
5x + 2 - 2 = 32 - 2
5x = 30
Divide both sides by 5
5x/5x= 30/5
x = 6
x+2x÷y-2y; x=4, y=-2
Substitute the value of the variable into the expression and simplify.

A rectangular garden is 6 feet longer than its wide. The perimeter of it is 52 feet. What equation can be used to find the width?
Answer:
Hi there!
Your answer is;
the equation
(w+6)+(w+6)+(w)+(w) = 52
The width of this rectangle is 10. The length of this rectangle is 16.
Step-by-step explanation:
Rectangular perimeter:
l+l+w+w
l= w+6
w= w
(w+6)+(w+6)+(w)+(w)
4w+12= 52
4w = 40
/4
w= 10
Hope this helps!

Which value of x makes the equation 1.25(4x - 10) = 7.5 true
Answer: x = 4
Step-by-step explanation:
1.25(4x-10)=7.5
5x-12.5 = 7.5
5x = 20
x = 4
Answer:
x=4
Step-by-step explanation:
1.25(4(4)-10)=7.5
1.25(16-10)=7.5
1.25(6)=7.5
7.5=7.5

∠A and ∠B are vertical angles. If m∠A=(3x-30)° and m∠B=(2x-9)°,then find the value of x.
Answer:
x = 21
Step-by-step explanation:
Vertical angles are congruent, thus
∠ A = ∠ B , substitute values
3x - 30 = 2x - 9 ( subtract 2x from both sides )
x - 30 = - 9 ( add 30 to both sides )
x = 21
Hello there! :)
[tex]\huge\boxed{x = 21}[/tex]
Vertical angles are congruent, therefore:
∠A ≅ ∠B
3x - 30 = 2x - 9
Subtract 2x from both sides:
3x - 2x - 30 = 2x - 2x - 9
x - 30 = -9
Add 30 to both sides:
x - 30 + 30 = -9 + 30
x = 21.

Start balance:
$63.44Deduction:
$186.56Balance after deduction:
$63.44 - 186.56 = -$123.12Deposit:
$123.12*1/4 = $30.78Balance at the end of the day:
-123.12 + 30.78 = -$92.343x-2(x+3)=4x-9-x is the question
Answer:
[tex]\large\boxed{x = 7}[/tex]
Step-by-step explanation:
3x - 2(x + 3) = 4x - 9 - x
Start by multiplying 2 by the values in the parenthesis
3x - 2x + 6 = 4x - 9 - x
Subtract 3x - 2x and 4x - x
x + 5 = 3x - 9
Add 9 to both sides of the equation
x + 14 = 3x
Subtract x from both sides of the equation
14 = 2x
Divide both sides of the equation by 2
