13r+23r=-2-1
36r=-3
r=-3/36
r=-1/12
Answer:
32
Step-by-step explanation:
Because if you put the lack of other side to the other side, it will complete.
One roll = 4
eight rolls = 4 × 8 = 32
Answer:
The fourth option - t = 3, y = 5
Step-by-step explanation:
-8 + t becomes -5, thus t is 3 since -8 + 3 = -5.
-12 becomes -2y - 2, so we can set these equal to each other as -2y - 2 = -12 and solve from there. Add 2 to both sides, -2y = -10, then divide by -2 on both sides, y = 5.
.05n + $28 = $50.50
(.05n = $22.50)100
5n = 2250
n= 450 calls
