Answer:
m<D = 52°
Step-by-step explanation:
x + 20 + 3x + 32 = 180
4x + 52 = 180
4x = 128
x = 32
m<D = x + 20 = 32 + 20 = 52°
Answer:
Step-by-step explanation:
152.55 = 2x - 9.45

Well what's your question
The answer is <span>B. 670

The mean average (X) is sum (s) of the values divided by the number of values n:
X = s / n
X = 83.750
n = 8
s = ?
s = X * n
s = 83.750 * 8 = 670
4 (.05) x +( .10)x =180
.20x + .10x = 180
.30x = 180
X= 6
So. 4 times 6 = 24 nickels and 6 dimes = 180 cents
