You need k by itself, so the only way to do that is to divide both sides by 5
Answer:
Let L be the length of the rectangle and w be the width of the rectangle.
"The lenght of a rectangle is one less than twice the width" means L=2W-1
Using perimeter formula of a rectangle which is P=2(L+W) you have:
P=2(L+W)
130=2(2W-1+W)
Solve equation above to find W
130=2(3W-1)
130=6W-2
130+2=6W
132=6W
W=22
From here you find L=2W-1=2x22-1=43
Only thing left is to find area A=LxW
You do the inverse operation for each one. so for #14, since 25g is multiplication you divide it by 25 to cancel it out, then you divide -175 by 25 which gives you -7
Answer:
The answer would be 8
Step-by-step explanation:
This equals 10-2=8
