Hey don’t worry about that grade just keep practicing maths and honestly at one point you’ll start understanding the concepts trust me. Just do it a lot.
So here are my explanations
Question: 2{4x - 3(x + 5) + 10} + 3(x - 2)
Steps
1. Expand 4x - 3(x + 5) + 10 = x - 5
= 2(x - 5) + 3(x - 2)
2. Expand 2(x - 5) = 2x - 10
= 2x - 10 + 3(x - 2)
3. Expand 3(x - 2) = 3x - 6
= 2x - 10 + 3x - 6
4. Then, simplify:
Add 2x + 3x = 5x
Add -10 - 6 = -16
5. Plug it in:
5x - 16 <-------------- Answer
Hope this helped!!!!
Answer:
m = 2
Step-by-step explanation:
m m+3
----- = ----------
4 10
Using cross products
10m = 4(m+3)
Distribute
10m = 4m+12
Subtract 4m from each side
10m-4m = 4m-4m+12
6m = 12
Divide by 6
6m/6 = 12/6
m = 2
