Answer:
3?
Step-by-step explanation:
Answer:
4 in, 8 in, 15 in
Step-by-step explanation:
If x, y, z are the three pieces, then:
x + y + z = 27
y = 2x
z = 3 + 3x
Substitute the second and third equations into the first.
x + 2x + 3 + 3x = 27
6x + 3 = 27
6x = 24
x = 4
y = 8
z = 15
Answer:
x=−3
Step-by-step explanation:
Move all terms that don't contain
x to the right side and solve.
hope this helps !
The slope is the change in Y over the change in X.
Find 2 points on the line that cross X and Y that are easy to tell what numbers they are.
First point( 0,-4)
Second point (8,0)
The change in Y would be 0 - -4 = 0+4 = 4
The change in X would be 8 -0 = 8
The slope is 4 / 8 which reduces to 1/2
The answer is C.
