Answer: x<17.5
Step-by-step explanation:
Subtract from both sides: x+2.5-2.5<20-2.5
Simplify the arithmetic: x<20-2.5
Simplify the arithmetic: x<17.5
Hope it helps!
Answer:
D, E, F
Step-by-step explanation:
The first step I would do is distribute the original equation. After distributing, the equation is now 8x² + 16xy. The first answer I see that matches this is D.
Then, after already eliminating A, B, and C, I look at E. I distribute the x and find out it is also equal to 8x² + 16xy.
Then, I look at F. After distributing again, it is also equal to 8x² + 16xy.
Answer:
y = 5
Step-by-step explanation:
This is a multi-step equation, so you can solve for the variable 'y' by using a series of steps:
1. Combine like terms:
-4y - 3 = 5 - 3y + 6 -19 or -4y - 3 = -3y - 8
2. Isolate the variable using inverse (opposite operations):
Add 8 to both sides: -4y - 3 + 8 = -3y - 8 + 8 or -4y + 5 = -3y
Add -4y to both sides: -4y + 5 + 4y = -3y + 4y
3. Solve for 'y'
5 = y
