Answer: 16a +8
Step-by-step explanation:
Put g(a) in f(a) in place of a l;ike this:
4(4a + 3) -4 =16a + 12 - 4 = 16a + 8
Answer:Add 4.3x to both sides of the equation.
Step-by-step explanation:
The given equation is expressed as
3.7x - 18 = - 4.3x - 34
The main aim is to solve for x and x is on the left hand side and the right hand side of the equation. So the most efficient step would be to make all the terms containing x to be on the left hand side of the equation and the constants to be on the right hand side of the equation.
Therefore, the most efficient first step to solve for x in the equation would be
Add 4.3x to both sides of the equation.
Answer:
(10, -20).
Step-by-step explanation:
y= -5x + 30
x = 10
Substitute x = 10 in the first equation:
y = -5*10 + 30
y = -50 + 30
y = -20.
So the solution is (10, -20).
C-7 hours, 0 minutes because between 8 and 11 are 3 hours and between 12 and 4 are 4 hours. 3+4= 7 hours
