Answer:
x = 1
Step-by-step explanation:
6(x+4)=30 (divide both sides by 6)
(x+4) = 30/6
x+4 = 5 (subtract 4 from both sides)
x = 5 - 4
x = 1
Data set 1: 14,15,17,18,21
mean: (14+15+17+18+21)/5 = 85/5 = 17
mad
17-14 = 3
17-15 = 2
17-17 = 0
17-18 = 1
17-21 = 4
(3+2+0+1+4)/5 = 10/5 = 2
17/2 = 8.5 is the means-to-mad ratio
Data set2: 15,16,17,20,22
mean = (15+16+17+20+22)/5 = 90/5 = 18
mad
18 - 15 = 3
18 - 16 = 2
18 - 17 = 1
18 - 20 = 2
18 - 22 = 4
(3+2+1+2+4)/5 = 12/5 = 2.4
18/2.4 = 7.5 means to mad ratio
Answer:
m = -2
Step-by-step explanation:
<em>Distribute first.</em>
24 = -6(m+1) + 18
24 = -6m - 6 + 18
<em>Then you combine like terms.</em>
24= -6m + 12
<em>Then you still combine like terms. You subtract 12 from each side.</em>
24 = -6m + 12
-12 - 12
12= -6m
<em>Then divide by -6 to isolate the variable.</em>
12 = -6m
/-6 /-6
-2 = m
