Answer:
Step-by-step explanation:
3(m-2)+2(m-2)
3m-6+2m-4
3m+2m-6-4
5m-6-4
5m-10
The expressions 3(m-2)+2(m-2) and 50m-2 are not equivalent expressions.
After simplifying the first expression 3(m-2)+2(m-2) in part (a), we got 5m-10, which is different from the second expression, 50m-2.
Answer:
Ok and, what is the question
Step-by-step explanation:
We have 20% and 60% solutions and need 80 ml of 50%
A) x + y = 80
B) .20x + .60y = (80 * .5)
Multiplying A) by -.2
A) -.2x -.2y = -16 Then adding this to B) we get
.4y = 24
y = 60 ml of 60%
x = 20 ml fo 20%
