3x + 10 = 20
-10. -10
3x = 10
x = 10/3
3(x +10) = 20
3x + 30 = 20
-30. -30
3x = -10
x = -10/3
Answer:
The number is 10/3
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
Three times a number increased by ten is equal to twenty
(3n) + 10 = 20
<u>Step 2: Subtract 10 from both sides</u>
3n + 10 - 10 = 20 - 10
3n = 10
<u>Step 3: Divide both sides by 3</u>
3n / 3 = 10 / 3
n = 10/3
Answer: The number is 10/3

Length (L): w + 3.5
width (w): w
Perimeter (P) = 2L + 2w
31 = 2(w + 3.5) + 2(w)
31 = 2w + 7 + 2w
31 = 4w + 7
24 = 4w
6 = w
Length (L): w + 3.5 = (6) + 3.5 = 9.5
Answer: width = 6 inches, length = 9.5 inches
