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.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
3x + 2 = 17
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract 2 on both sides: 3x = 15
- [Division Property of Equality] Divide 3 on both sides: x = 5
Answer:
The first one is 1:4
The second one is most likely 0.2:1
Im not quite sure though. Hope you get a good grade!
