Answer:
-7
Step-by-step explanation:
-9x-3=60
add 3 to each side to cancel -3
-9x-3+3=60+3
simplify
-9x=63
divide by -9 to cancel the -9
-9x/-9=63/-9
simplify
x=-7
Answer:
r=3
Step-by-step explanation:
3(r - 7) = 4(2 - 2r) + 4
Distribute
3r -21 = 8 -8r +4
Combine like terms
3r -21 = 12 -8r
Add 8r to each side
3r +8r-21 = 12 -8r+8r
11r -21 = 12
Add 21 to each side
11r -21+21 =12+21
11r = 33
Divide each side by 11
11r/11 = 33/11
r = 3
Answer:
6 shirts
Step-by-step explanation:
she spent 56 in total
56-20 for the pants
36 left and she bought 6 shirts
36 divided by 6
6
The three consecutive integers are n, n+1, and n+2. They add up to -36 so n + n+ 1 + n+ 2 = -36. So 3n + 3 = -36. Subtract 3 from both sides. 3n = -39. Divide both sides by 3 to isolate n. N=-12. The integers are -12, -11, and -10. Good luck
Answer:
