You just need to isolate x. Subtract 3 from 15, add three to both sides then divide by 5.
5x-3=15-3
5x-3=12
5x=15
x=3
$1 = 2 weeks

<u>Multiply by 800:</u>
$1 x 800 = 2 x 800 weeks
$800 = 1600 weeks

Answer:
15 sq. cm.
Step-by-step explanation:
Each of the full squares are 1 so each of the half squares are .5
There are 12 full squares and 6 half squares. If you add those half squares you will get 15 sq. cm.
49 x 138 = 6762
37 x 49 =1813
6762 - 1813 = 4949 so your answer is 4949.
