4/5. To divide fractions, you multiply by the reciprocal (flip the second fraction). This gives us (-3/5) x (4/-3). Since there is a -3 on the top and the bottom, they cancel out. That leaves 4/5.

If 2x+y=5, then y=5-2x, so he substituted 5-2x correctly.
x+4x=5x, so he combined like terms correctly.
If 5x-10=10, then 5x=10+10 -> 5x=20, so he subtracted 10 from the right side instead of adding 10 to the right side.
The answer is C.
Here's the correct solution:
Writing equivalent equations help you solve system of equations because it sets it up for being broken down part by part.
Answer:
89 dollars
Step-by-step explanation:
47 and 53 cents make one dollar together. 12 dollars and 76 dollars make 88 dollars. 1+88=89
The inequality passing through (1, 4), (-2, -2), intersecting the y-axis at 2 units and intersects the x-axis at (-1, 0) to form shaded portions on the left side is y > 2x+2
<h3>What is an
