then 130÷4=3.5 for the first piece and 130-3.5=9.5
Perimeter of any figure is all its sides summed up
for a rectangle, with two equal pairs, that means, length + length + width + width or 2length + 2width, or 2(length + width)
but we know the length is 7/5 the width
width = w
perimeter = P

and the length is 7/5 of that
Answer:
f(-7) = -6
f(10) = 9
Step-by-step explanation:
Because -7 is less than 0 you can use the top equation -7 + 1 to get 6
Because 10 is greater than 0 you can use the bottom equation 10 - 1 to get 9
Answer:
m=2
Step-by-step explanation:
Add the numbers
-7+4m+10=15-2m
3+4m=15-2m
Rearrange terms
3+4m=15-2m
4m+3=15-2m
Rearrange terms
4m+3=15-2m
4m+3=-2m+15
Subtract 3 from both sides of the equation
4m+3=-2m+15
4m+3-3=-2m+15-3
Simplify
4m=-2m+12
Add 2m to both sides of the equation
4m=-2m+12
4m+2m=-2m+12+2m
Simplify
6m=12
Divide both sides of the equation by the same term
6m = 12
6m/6 = 12/6
Simplify
m = 2
