Answer:
p + 4p
5p
Step-by-step explanation:
Problems Vicki solved = p
Tamra worked 4 times as many problems as Vicki = 4 x p = 4p
total problems solved by both of them =4p + p
= 5p
Answer:
Height(h) = 24in
Area = 204in²
Step-by-step explanation:
we would use the heron formula because we have all the sides to calulate the area
S = (A+B+C)/2 = (25 + 17 + 26)/2 = 68/2 = 34
area = √s(s-a)(s-b)(s-c) = √34(34-25)(34-17)(34-26) = √34(9)(17)(8) = √34x9x17x8 = √41616 = 204
area= (1/2)bh
204 = (1/2)bh b= 17, h =?
204 = (1/2)17h
204 x 2 = 17h
408 = 17h
h = 408/17 = 24in
Height(h) = 24in
Area = 204in²
Answer:
Step-by-step explanation:
Simplifying
5(x + 3) = 45
Reorder the terms:
5(3 + x) = 45
(3 * 5 + x * 5) = 45
(15 + 5x) = 45
Solving
15 + 5x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-15' to each side of the equation.
15 + -15 + 5x = 45 + -15
Combine like terms: 15 + -15 = 0
0 + 5x = 45 + -15
5x = 45 + -15
Combine like terms: 45 + -15 = 30
5x = 30
Divide each side by '5'.
x = 6
Simplifying
x = 6
