Answer:
r = 1
Step-by-step explanation:
Use the distributive property to multiply −6 by −3+5r.
18−30r=−5−7r
Add 7r to both sides.
18−30r+7r=−5
Add −30r and 7r to get −23r.
18−23r=−5
Subtract 18 from both sides.
−23r=−5−18
Subtract 18 from −5 to get −23.
−23r=−23
Divide both sides by −23.
r=−23/−23
Divide −23 by −23 to get 1.
r=1
You can just guess numbers that could be x, I tried 80 and it got me 32 so I tried 60 and it got me 28 I tried 70 and it got me 30=16+1/5(70)
Answer:
d
Step-by-step explanation:
if she connects it to any other point angle would be more the 30 degree
X - the price of each pair of shoes;
3 x + 7.50 + 0.06 * 3 x = 126.81
3 x + 0.18 x + 7.50 = 126.81
3.18 x = 126.81 - 7.50
3.18 x = 119.31
x = 119.31 : 3.18
x = 37.52
