Answer:
4.5
Step-by-step explanation:
The sum of 3 and 7 is 10
then what number to you multiply 10 by to get 45
45 ÷ 10 = 4.5
so the answer is 4.5
Answer:
Area is almost the same as surface area. However, surface area is more complicated, and you have to split the object that you are measuring into different parts to get their area before you can find the whole surface area.

Answer:
x - y = 14
Step-by-step explanation:
sum the parts of the ratio, 5 + 3 = 8 parts
Divide 56 by 8 to find the value of one part of the ratio.
56 ÷ 8 = 7 ← value of 1 part of the ratio, thus
x = 5 × 7 = 35
y = 3 × 7 = 21
Thus x - y = 35 - 21 = 14
We can solve these two polynomials as follows:
The answer to this subtraction is then:
Answer:
y = 2x + 9.
Step-by-step explanation:
Using the point-slope form:
y - y1 = m(x - x1) where m = the slope and (x1, y1) is a point on the line.
So here we have:
y - 1 = 2(x - (-4))
y - 1 = 2(x + 4)
y - 1 = 2x + 8
y = 2x + 9.
