Answer:
Part A : 4 (m+3+5m) = 4(6m+3) = 24m+12
Part B: 4 (m+3+5m) combine like terms
4 (6m+3)
24m + 12 Distribution
Part C: m = 3 random number
4 (3 + 3 + 5(3)) = 24(3)+12
4(21) = 72 + 12
84 = 84

Answer:
Step-by-step explanation:
m = number of minutes
$ 8 monthly fee + 19 cents per minute
the expression for this is : 8 + 0.19m
$ 25 monthly fee and 14 cents per minute
the expression for this is : 25 + 0.14m
to find out when they will be equal, just set them equal to each other and solve for m, the number of minutes
8 + 0.19m = 25 + 0.14m .....subtract 0.14m from both sides
8 + 0.19m - 0.14m = 25......subtract 8 from both sides
0.19m - 0.14m = 25 - 8.....combine like terms
0.05m = 17...divide both sides by 0.05
m = 17 / 0.05
m = 340 <==== they are both the same at 340 minutes
I could be wrong but 20.5 and 7.5
Answer:d
Step-by-step explanation:
Answer:
11.true 12. a > c 13. if x > or < c that means x is ALL numbers greater or less than c. numbers are infinitely positive and negative so all numbers greater or less than c go up to infinitely or down to negative infinity amount
Step-by-step explanation:
11. replace x with 2, 112/8 + 2 ≥15 + 4(2) -7. solve 14+2≥15+8-7 , 16≥23-7, 16≥16 true
12. if a is greater than b we can assume a is greater than c as well because b is greater than c
