Answer:
x = 21/8
Step-by-step explanation:
Step 1: Write equation
x - 11 = 3 - 7(x - 1)
Step 2: Solve for <em>x</em>
<u>Distribute -7:</u> x - 11 = 3 - 7x + 7
<u>Combine like terms:</u> x - 11 = 10 - 7x
<u>Add 7x on both sides:</u> 8x - 11 = 10
<u>Add 11 on both sides:</u> 8x = 21
<u>Divide both sides by 8:</u> x = 21/8

Answer:
All the options are correct apart from the last one
Step-by-step explanation:
- <em>Scale factor is the ratio of corresponding sides</em>
Scale factor = 6.5 / 3.25
Scale factor = 3.25 / 6.5
Scale factor = 3 / 1.5
Scale factor = 1.5 /3
Scale factor = 1.5 / 3.25
- No, as it is the ratio of sides of the same rectangle
