Answer:
the answer is 31w.
Step-by-step explanation:
first you work in the parentheses 48 - 17 which is 31. then your w has to be put in to multiply if you knew the value of w.
What is the missing value that makes the equation true?
32 + 12 – 6 = 52
13 +
Answer: 3
Explanation:
3^2 + 12 - 6 = 5^2 - 13 + (?)
start with 3^2 or 3x3 giving us 9 then we add 12 to it 9+12=21 subtract 6. 21-6=15 then we have to make the next part equal 15 so we start off by seeing how much we have so 5^2 or 5x5=25 then subtract 25-13=12 so that means we have to see what we need to add to this to make it 15 which is 3 so that means your answer is 3
3^2 + 12 - 6 = 5^2 - 13 + 3

How many times larger than 71 is 710?
Answer:10
Step-by-step explanation:
If A(2, x) , B(x, 8) and AB = 3√2 cm, then x = ?
Answer:
x =5
Step-by-step explanation:
Using the formula for calculating the distance between two points
D = √(x2-x1)²+(y2-y1)²
Given the points A(2, x) , B(x, 8) and AB = 3√2
On substituting the given values into the formula;
AB = √(x-2)²+(8-x)²
3√2= √(x-2)²+(8-x)²
square both sides
(3√2)²= (x-2)²+(8-x)²
18 = (x-2)²+(8-x)²
expand
18 = x²-4x+4+64-16x+x²
18 = 2x²-20x+68
2x²-20x+68-18 = 0
2x²-20x+50 = 0
x²-10x+25 = 0
Factorize
x²-5x-5x+16 = 0
x(x-5)-5(x-5) = 0
(x-5)(x-5) = 0
x-5 = 0 an x-5 = 0
x = 5

What value of x balances the scale?
Answer:
X = 5
Step-by-step explanation:
For the equilibrium position of the scale,
Weights on both the sides of the scale should be equal.
Weights on left side of the scale = Weights on the right side
Weights denoting X + Weights denoting (-1) = Weights denoting (X) + Weights denoting (1)
5(X) + 6(-1) = 3(X) + 4(1)
5X - 6 = 3X + 4
5X - 3x = 6 + 4
2X = 10
X = 5
Therefore, For X = 5, scale will be in the balanced position.

byron earns $11.00 per hour will byron have to work to earn $143.00?
Answer: 13 hours
Step-by-step explanation:
Money earned per hour = $11.00
Amount he plans to earn = $143. 00

Therefore, Bryon will have to work of 13 hours to earn $ 143.00
Answer:
13 hours!
Step-by-step explanation:
All I did was divide $143.00 by $11.00 and got 13!
Or you could multiply $11.00 by 13 to get $143.00

Aisha has 3 pizzas. She is serving each person at a party 14 of a pizza. How many people can she serve at the party? Use the number line to help you solve the problem.[ Please help TwT]
Given:
Aisha has 3 pizzas.
She is serving each person at a party 1/4 of a pizza.
To find:
The number of people she can serve at the party.
Solution:
Let the number of people be x.
Number of pizzas is 3. So, each person get [tex]\dfrac{3}{x}[/tex] part of pizza.
It is given that each person get 1/4 of a pizza.
[tex]\dfrac{1}{4}=\dfrac{3}{x}[/tex]
Using cross multiplication, we get
[tex]1\times x=3\times 4[/tex]
[tex]x=12[/tex]
Therefore, the number of persons in 12.
Now, divide the number line in four equal parts between each pair of consecutive integers.
Then, count the marked points from 0 to 3 excluding 0. These points represent number of persons.
-2(x+3)5=11 i need help on that
Answer:
x=-4.1
Step-by-step explanation:
Multiply 5 by −2.
−10(x+3)=11
Divide each term by −10 and simplify.
x+3=−11/10
Move all terms not containing x to the right side of the equation.
x=−41/10
The result can be shown in multiple forms.
Exact Form:
x=−41/10
Decimal Form:
x=−4.1
Mixed Number Form:
x=−4 1/10
0.7x-1.4=-3.5 what is the value if x
Answer:
x = -3
Step-by-step explanation:
Step 1: Add 1.4 to both sides.
0.7x − 1.4 + 1.4 = −3.5 + 1.4
0.7x = −2.1
Step 2: Divide both sides by 0.7.
0.7x/0.7 = −2.1/0.7
x= −3
Hope this helps
Answer:
x= -3
Step-by-step explanation:
add 1.4 on both sides giving you
0.7x/0.7 = -2.1/0.7 and 0.7x cancels out leaving you with -2.1 divided by 0.7
when you divide you Get -3

Answer:
real numbers, including the boundary lines
Step-by-step explanation:
The inequality symbols in this system both include the "or equal to" case, so the boundary lines of the "shaded area" are part of the solution set.
Ordinarily, weight is a continuous variable, so we presume the weights of almonds and cashews may be any real number. The problem statement gives no clarity in that regard, so it is entirely possible that the given nuts will only be delivered in packages with integer weights.
Based on our presumption, the solution set is best described as below.
_____
Additional comments
Each inequality gives rise to a "shaded region," as shown in the second attachment. The solution set will be the doubly-shaded region, limited to the first quadrant. (Quantities of nuts cannot be negative.) Strictly speaking, the answer choices are all incorrect.

per month. How many GB of data would he have to use in a month to make both
plans cost the same? Which plan would you recommend he use?
Answer:
he would have to use all of it and then $16 more to make both plans cost the same. I think he should go with US Cellular

m(x) = 3x – 2
n(x) = x +4
Find m(n(x)).
You get 60 points
Answer:
3x+10
Step-by-step explanation:
Plug n(x) into the x of the m(x) and the answer is m(n(x)).
m(x) = 3x - 2
n(x) = x + 4
Plug in n(x) to m(x) as shown here
m(n(x)) = 3(x + 4) - 2
distribute the 3
m(n(x)) = 3x + 12 - 2
simplify
m(n(x))= 3x + 10
