Step-by-step explanation:
250 x 0.35 = 87.5
Answer:
2
Step-by-step explanation:
To solve this question, we can do it both ways. we can get rid of the 7 by dividing it, or we can distribute it to the parenthesis. let's do this the distribution way.
63=7(5+7b)
When distributing, the number behind (7) goes to both and all terms in the parenthesis.
63=7(5)+7(7b)
Multiply.
63=35+49b
Subtract 35.
28=47b
Divide by 49.
0.57=b
Solve for m:
(-3 m)/7 = 12
Multiply both sides of (-3 m)/7 = 12 by -7/3:
(-7 (-3) m)/(3×7) = (-7)/3×12
(-7)/3×(-3)/7 = (-7 (-3))/(3×7):
(-7 (-3))/(3×7) m = (-7)/3×12
(-7)/3×12 = (-7×12)/3:
(-7 (-3) m)/(3×7) = (-7×12)/3
(-7)/7 = (7 (-1))/7 = -1:
(-3-1 m)/3 = (-7×12)/3
(-3)/3 = (3 (-1))/3 = -1:
--1 m = (-7×12)/3
(-1)^2 = 1:
m = (-7×12)/3
12/3 = (3×4)/3 = 4:
m = -74
-7×4 = -28:
Answer: m = -28
