Step-by-step explanation:
w = 3(2a + b) - 4
w = 6a + 3b - 4
6a = w - 3b + 4
a = 1/6 * (w - 3b + 4).
In order to find the equation of a line, you would have to use the equation y=mx+b.
First, find the slope:

There is (1,8) and (2, 16) so plug that in 16-8/2-1 = 8. That's your slope! (Or the m)
Next in order to find b, you have to plug in a point:
y=8x+b
Take (1,8) and plug it in for x and y:
8=8(1)+b
b=0
Your y intercept is 0 (which you can also see on the graph)
So your answer is: y=8x
Answer:
The bus travelled 60 miles in 1 hour.
Step-by-step explanation:
To solve this problem we need to calculate the average speed at which the bus travelled. This is given by the distance travelled divided by the time that they took to get there. So we have:
average speed = distance/time
average speed = 360/6
average speed = 60 miles/h
Therefore in 1 hour they travelled 60 miles.

The coefficient of the x term is -32.
Answer:
39
Step-by-step explanation:
6x-15+3x+6=90
Simplify: 9x-9=90
9x=99
x=11
3(11)+6
33+6
