Answer: m = n-1
Step-by-step explanation:
7m+2 = 7n-5
7m = 7n-5-2
7m = 7n - 7
Divide both sides by 7,
m=n-1
Answer:
52 pages per 1 hour
Step-by-step explanation:
If Penny reads 13 pages in 1/4 of an hour you need to multiply 13 by 4 to see how many pages she will read in 1 hour.
The sum of the inside angles of a 5 sided figure needs to equal 540 degrees.
Add all the angles together to equal 540 and solve for x. Once you have the value for x you can use that to figure out all the angles.
X-8 + 3x-11 + x + 8 + 2x + 7 + x = 540
Simplify by combing like terms:
8x - 4 = 540
Add 4 to both sides:
8x = 544
Divide both sides by 8:
X = 68
Now replace x with 68 in each angle and solve:
U = 68-8 = 60
V = 3(68)-11 = 204-11 = 193
W = 68 + 8 = 76
Y = 68
Z = 2(68) + 7 = 136 + 7 = 143
Answer:Yes. The standard deviation is the square root of the variance, and the variance is the average of (distance from the mean) squared.
