<em>2x - 5 + 3x = 35
</em>
<em>simplify
</em>
<em>5x - 5 = 35
</em>
<em>add 5 to both sides
</em>
<em>5x - 5 + 5 = 35 + 5
</em>
<em>simplify
</em>
<em>5x = 40
</em>
<em>divide both sides by 5
</em>
<em>5x/5 = 40/5

Answer:
9% decrease
Step-by-step explanation:
Percentage Decrease = [ (Starting Value - Final Value) / |Starting Value| ] × 100

Answer:
B. 16.19
Step-by-step explanation:
We have given height to width ratio of two similar rectangles
Hence, we solve using Proportionality
Height a/Width a = Height b/Width b
21/34 = 10/w
Cross Multiply
21 × w = 34 × 10
w = 34 × 10/21
w = 16.19047619
Approximately to decimal places = 16.19
Option B is correct
