You can make 3 tens blocks and then 3 tens blocks but only two should be filled than for the third one fill 7 only
Rectangle:
P = 2 (L+W) but length is 2 meters longer than wide
then L = W + 2, So
P = 2 (L + W)
24 = 2(W+2+W)
24 = 2 (2 + 2W)
24 = 4 + 4W
So 4W = 24 -4 =20
W = 20/4= 5, L = 5+2= 7
Double check
24 = 2*(5+7) = 2 *12 = 24
22-7-7-7=1 this will show that you can subtract 7 three times from 22 and have a remainder of 1.
Answer:
I'll help you out. Question: Are you solving for A or for N?
If you're solving for A: A=10n + 7
If you're solving for N: Isolate the variable by dividing each side by factors that don't contain the variable. n = A/10 - 7/10
Hope this helped!
