Answer:
x ≥ -5
Step-by-step explanation:
1. Distribute the -2 through the parentheses
-2(x + 4) = -2x - 8
2. Combine like terms ( 6 plus -8)
6 - 2x - 8 ≤ 8
-2 - 2x ≤ 8
3. Move the constant to the right-hand side and change its sign
-2x ≤ 8 + 2
4. Combine like terms
-2x ≤ 8 + 2
-2x ≤ 10
5. Divide on both sides
-2x /-2= cancels out ≤ 10/-2 = -5
x ≥ -5
Tip: if you have a negative x value you must flip the sign

The length-to-width ratio of a television screen is 4 to 3. Mya bought a television with a length of 60 inches. What is the width of the television?
a. 45 inches
b. inches
c. 50 inches
d. 52 inches
Answer:
A
Step-by-step explanation:
Since the first screen, the length is 4 and width is 3, you multiply until you get to 60. 4×15=60, so what is 3×15? 45.
Answer: A
Step-by-step explanation:
Length ratio = 4x
Width ratio = 3x
Length = 60
∴ So, that means, 4x = 60
x = 15
Now, Width = 3*15 = 45 inches
Option (a) is correct
