Answer:
See below ~
Step-by-step explanation:
<u>Given</u>
- Area = 490 units²
- Width = 5x
- Length = 8x
Now, we know that : length x width = area
<u>Using the given values</u>
- (8x)(5x) = 490
- 40x² = 490
- x² = 490/40
- x² = 49/4
- x = √49/4
- x = 7/2 = 3.5
<u>Length (l)</u> = 8x = 8(3.5) = <u>28 units</u>
<u>Width (w)</u> = 5x = 5(3.5) = <u>17.5 units</u>

Answer:
= y/2
Step-by-step explanation:
(x+3)/3 = (y+2)/2
x/3 + 1 = (y+2)/2
x/3 = (y+2)/2 - 1
= (y+2-2)/2
= y/2
hope this helped(:
