15. x ≤ -24
x + 19 ≤ -5
x ≤ -24
16. z > -12
3z > -36
z > -12
17. 185 + c > 410; c > 225
18. C.
x - 6 ≥ 1
x ≥ 7
Divide 3 from both sides to get a=57/3 then a=19
Answer:
Step-by-step explanation:
47+34=9k
81=9k
k=81/9=9
k=9
Assuming that is a 24 the answer would be 24[10] = 240 but if that is the question 2 and the number is just 4 the answer is just 40
M= 2.8
Alternate form:
14/5 or 2 4/5
