Answer:
5(x-4y) or 5x-20y
Step-by-step explanation:
4(2x-5y)-3x
8x-20y-3x
Subtracting 8 and 3
5x-20y
Answer:
the goal is to try and get x alone. For the 1st problem, x=3.
Step-by-step explanation:
3x + 1 = 10 Subtract 1 both sides to cancel out the 1 on the left side. 10-1 = 9
3x = 9 To get x alone here, Divide 3 on both sides. 9/3 = 3
x = 3 Now x is alone, which means x = 3.
This is right because if you plug x with 3, the sum = 10.
(3*3) + 1 =10
9 + 1 = 10
So, that's how you know 3 is the right answer.
If the line is parallel to y-axis, then x is a constant for that line. x for the given point equals 2, so all other points of the line will have x=2.
An equation for the line that passes through the point (2, −9) and is parallel to the y-axis is x=2.
Break into 2 seperate shapes:
top section: 5 * 5 * 5 = 125
lower part" 5 * 20 * 5 = 500
500 + 125 = 625
answer is A
