Answer:
16 cm
Step-by-step explanation:
Suppose that x is the original width. If that original width is enlarged by a scale factor 5/2 that means that x is multiplied by 5/2 and after that multiplication we obtained new width, 40 cm.
Therefore,
x*(5/2) = 40
We multiply the equation by 2 and obtain:
x*5 = 40*2
5x = 80
Now we divide the equation by 5 and obtain:
x = 80/5
x = 16
We obtained that x, the original width was 16 cm
2*5=10 (the measure of one long side is 10)
3*4=12 (the measure of one wide side is 12)
A box has four sides to the perimeter of the flat wrapping paper must consist of four edges. Because we know that one edge is 10 inches long and another side is 12 inches wide we assume that the corresponding sides are equal.
So now we know that we have two sides that are 10 inches and 2 sides that are 12 inches.
10+10+12+12= 44 inches
Answer:
d= -2
Step-by-step explanation:
7 + 4d + 5d = 7d + 3
Combine like terms
7+9d = 7d+3
Subtract 7d from each side
7+9d-7d = 7d-7d+3
2d +7 = 3
Subtract 7 from each side
2d+7-7 = 3-7
2d = -4
Divide each side by 2
2d/2 = -4/2
d = -2
