Answer:
x = 6y
Step-by-step explanation:
x = 3z and z=2y
Substitute the second equation into the first
x = 3 (2y)
x = 6y
It’s either B or D. I’m sorry I’m not so sure but I think it’s either one of those.
Answer:
An equation of a line with slope -3/2 and x-intercept (4,0) will be:

Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
Given
now substitute m = -3/2 and the point (4, 0) in the slope-intercept form of line equation



Add 6 to both sides

Simplify

Thus, the y-intercept b = 6
now substitute m = -3/2 and b = 6 in the slope-intercept form of line equation


Therefore, an equation of a line with slope -3/2 and x-intercept (4,0) will be:

Answer:

Step-by-step explanation:
By factorization, we get ----

Answer:
n = 12
Step-by-step explanation:
(n-8)x 7 = 28
n-8 = 4
n = 12
