M*10-m*2=8
10m-2m=8
8m=8
Divide both sides by 8:
m=8
Fill in the m's:
1*10-1*2=8
10-2=8
8=8
Hope this helps :)

Mean:
a) 1+4+2+1 = 8/4=4
b)1+5+2+1 = 9/4= 2.25 (round to the nearest whole number = 2)
c) 1+5+1+0 = 7/4 = 1.75 (round to the nearest whole number = 2)
d) 1+4+1+0 = 6/4 = 1.5 (round to the nearest whole number = 2)
Answer:
B
Step-by-step explanation:
If you're looking for direct correlation, you're looking for a proportion for the second box. So you set the ratio of 2.5:5.5 up as a fraction. 2.5/5.5 and set it equal to the second box 3/x.
2.5 = 3
5.5 x
cross multiply
16.5=2.5x
and divide
16.5/2.5 and you get your answer
Answer:
√30
Step-by-step explanation:
We can find the value of x by using Euclidean theorem
x^2 = 3 × 10
if x^ = 30 then x = √30
Answer:
-8 > b
Step-by-step explanation:
94<-2(1+6b)
Distribute
94<-2-12b
Add 2 to each side
94+2<-2-12b +2
96 < -12b
Divide each side by -12, remembering to flip the inequality since we divide by a negative
96/-12 > -12b/-12
-8 > b
