3m=5(m+3)-3 How do I solve it
2 answers:
Simplifying
3m = 5(m + 3) + -3
Reorder the terms:
3m = 5(3 + m) + -3
3m = (3 * 5 + m * 5) + -3
3m = (15 + 5m) + -3
Reorder the terms:
3m = 15 + -3 + 5m
Combine like terms: 15 + -3 = 12
3m = 12 + 5m
Solving
3m = 12 + 5m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-5m' to each side of the equation.
3m + -5m = 12 + 5m + -5m
Combine like terms: 3m + -5m = -2m
-2m = 12 + 5m + -5m
Combine like terms: 5m + -5m = 0
-2m = 12 + 0
-2m = 12
Divide each side by '-2'.
m = -6
Simplifying
m = -6
Answer:
m = -6
Step-by-step explanation:
First you distribute 5 into (m+3) so it would 5m + 15
The equation now would be:
3m = 5m + 15 - 3
3m = 5m + 12
3m - 5m = 5m -5m + 12
-2m = 12
-2m/-2 = 12/-2
m = -6

Step-by-step explanation:
because look at the tail
1) 4/5 + 4/5 = 1 3/5
2) 4/5 + 2/5 + 2/5 = 1 3/5
A = allowance
(1/2)a = what have left after Monday
(1/2(1/2)a = what you have after Tuesday
(1/2)(1/2)(1/2)a = what you have after Wednesday.
Doing the multiplication.
(1/8)a = what you have left.
You have 1/8 of what you had at the start.
2 flowers are 5.5 feet tall and 4 are 7 feet tall, you subtract 2 from 4 and get 2.
2 flowers is the answer.
