Answer:
Width is 18 inches
Perimeter is 99 inches
Area is 567 square inches
Step-by-step explanation:
The ratio of width to length is 4 : 7
The length is 31.5 inches
The width = (31.5 ×4) ÷ 7 = 18 inches
Perimeter = 2(length + width)
Perimeter = 2(31.5 + 18) inches = 99 inches
Area =length × width
Area = 31.5 inches × 18 inches = 576 square inches.
5(-4m - 4) - 8(3m + 7) ≤ -76
Distribute 5 and -8 inside their respective parentheses.
-20m - 20 - 24m - 56 ≤ -76
Combine like terms.
-44m - 76 ≤ -76
Add 76 to both sides.
-44m ≤ 0
Divide both sides by -44 and flip the inequality sign because you are dividing by a negative number.
m ≥ 0
D) m ≥ 0

Answer:
b = 30 degrees
a = 150 degrees
Step-by-step explanation:
Let's call <em>a</em> to the first angle and <em>b</em> to the second one. So we have:
a = 5*b (1)
and it says that the greater angle has 120 degrees more than the lesser angle. So It will be:
a = 120+b (2)
We just need to solve both equations. We can equal both of them.
5b = 120+b
4b = 120
b = 30 degrees
Therefore a = 5*30 = 150 degrees
a = 150 degrees
I hope it helps you!
