Answer:
x=−y−3
Step-by-step explanation:
x+y=−3
Step 1: Add -y to both sides.
x+y+−y=−3+−y
x=−y−3
Answer:
B.distance = speed × 90
Step-by-step explanation:
We know that distance = rate * time
We know the time is 90 minutes
distance = speed * 90
Answer:
The distance from the flagpole to the tree is 27 ft
Step-by-step explanation:
Given equation: 3(x + 4) + 2 = 2 + 5(x – 4).
<em>First step is to distribute 3 on left side and 5 on right side of the equation,</em> we get
3x + 12 + 2 = 2 + 5x – 20
<em>Second step is combining like terms, 12+2=14 and 2-20=-18.</em>
We get
3x +14 = 5x -18.
<h3>Third step, we need to get rid 18 from right side and 3x from left side.</h3>
<em>Adding 18 on both sides and subtracting 3x from both sides</em>, gives
32 = 2x.
<h3>Fourth step , we need to get rid 2 from right side from 2x.</h3>
<em>We need to divide both sides by 2</em>, we get
16=x.
