Step-by-step explanation:
I hope this helps.
Answer:
15
Step-by-step explanation:
GH = (BC + FE) /2
9x-3 = (19+ 5x+1) /2
2* (9x-3) = 19+ 5x+1
18 x - 6 = 5x + 20
13x = 26
x = 2
GH = 9*2 - 3 = 15

Answer:
85%
Step-by-step explanation:
There are 4·5=20 boxes total.
4·4+1=16+1=17 of them are purple
17/20
17/20 as a decimal is 0.85
To convert a decimal into a percent multiply it by 100
0.85·100=85%
Answer:
4x+20=
6x-10
Step-by-step explanation:
Simplifying: 4x + 20 = 6x + -10
Reorder the terms: 20 + 4x = 6x + -10
Reorder the terms: 20 + 4x = -10 + 6x
Solving: 20 + 4x = -10 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation: 20 + 4x + -6x = -10 + 6x + -6x
Combine like terms: 4x + -6x = -2x: 20 + -2x = -10 + 6x + -6x
Combine like terms: 6x + -6x = 0: 20 + -2x = -10 + 0: 20 + -2x = -10
Add '-20' to each side of the equation: 20 + -20 + -2x = -10 + -20
Combine like terms: 20 + -20 = 0: 0 + -2x = -10 + -20: -2x = -10 + -20
Combine like terms: -10 + -20 = -30: -2x = -30
Divide each side by '-2': x = 15
Simplifying: x = 15
