2 step equations are equations that require 2 steps to solve it.
For example, 2x + 5 = 3x + 6
To solve for x, we must isolate it.
First subtract 2x on both sides, which is ONE step.
2x + 5 = 3x + 6
-2x -2x
5 = x + 6
The we must subtract 6 from both sides of the equation, which makes is the second step.
5 = x + 6
-6 -6
-1 = x
-1 would be the answer and we only used 2 steps to solve it.
Answer: 4
Step-by-step explanation:
Perpendicular lines have reciprocal slopes
Your answer would be option B. 2y² - y - 6 = 0. This is because if you were to substitute x = y² - 1 into the equation 2x - y = 4, you would get 2(y² - 1) - y = 4, which expands into 2y² - 2 - y = 4, and then simplifies to 2y² - y - 6 = 0.
I hope this helps!
Answer:33.3
Step-by-step explanation: a mile is 1000×3 so it's 3000/90
Longest book: 396 Shortest book: 1/4×396=99 Middle book: 3×99= 297
<span>
If the book in the middle of her shelf has three times the number of pages of the shortest book then how many pages does the middle book have?
Answer: 297</span>
