Step-by-step explanation:
-7(-3r+2)=3r-6
Distribute the - 7
21r-14=3r-6
Add 14
21r=3r+8
Subtract 3r
18r=8
Divide 18r by 8
2.25 should be the answer to r.
It’s letter d
since m and n are parallel the measure of b will be equivalent to the angle 35 degrees
C. 32in. >> 10+10+6+6=32.
You have no choices listed but here's the answer:
(85 + 91 + x) / 3 = 94
Multiplying both sides by 3
85 + 91 + x = 282
x = 106
In order for her to get a 94 average she would need a mark of 106 on her next test.
