The answers are b and c hope this helps
Answer: r=-7/6y+7/2
Step-by-step explanation:
Step 1: Add -5 to both sides.
6r+5+−5=−7y+26+−5
6r=−7y+21
Step 2: Divide both sides by 6.
6r/6=-7y+21/6
Answer: Rectangle
If you let
P = (0,0)
Q = (0,b)
R = (a,b)
S = (a,0)
you'll be able to find that
PQ is a vertical line with undefined slope
QR is a horizontal line with slope 0
so PQ and QR form a right angle as they are perpendicular lines
You'll find this with the other line pairings as well. We'll have four right angles
1 gal + 2 qt + 3 pts
1 gal + 3 qt + 7 pts
1 gal + 3 qt + 3 pts
----------------------------add
3 gal + 8 qt + 13 pts
1 gal = 4 qts
1 gal = 8 pts
1 pt = 1/2 qt
13 pts = 6.5 qts
now we have 3 gal + (8 + 6.5) = 3 gal + 14.5 qts
12 qts = 3 gal
now we have : 6 gal + 2.5 qts or 6 gal + 2 qts + 1 pt <=== answer
The correct answer is A.
That is because the whole paragraph talks about a model car that they are testing but this student is wondering about roller coasters.
Hope this helps :)
