Answer:
- 2x - 31
Step-by-step explanation:
Given
- 3(4x + 5) - 2(- 5x + 8)
Multiply the terms in the first parenthesis by - 3 and the terms in the second parenthesis by - 2
= - 12x - 15 + 10x - 16 ← collect like terms
= (- 12x + 10x) + (- 15 - 16)
= - 2x - 31
Answer:
Elgas is 9 years old.
Step-by-step explanation:
Alvin: 3 x Elgas
36: Alvin + Elgas
36 / 4 : 9
Elgas: 9
Alvin: 27
To check: 27 + 9= 36
Answer:8.5
Step-by-step explanation:
Pythagorean Theorem
A
a^2 + b^2 = c^2
3^2 + 8^2 = c^2
9 + 64 = c^2
73 = c^2
C= Sqrt (73)
C = 8.5
Answer:
a = 50t
Step-by-step explanation:
The graph goes through (0,0) so the y intercept is 0
a=5t
a=50t
a=50 + t not it
a=10t
The slope is y/x since the y intercept is 0
m = 50/1 = 50
The equation for the line is
y = 50x+0
y = 50x
Using the variables given
a = 50t
