Answer:
Step-by-step explanation:
0.9*2b = 1.8b
0.9*-1 = -0.9
So far we have 1.8b-0.9. It can't be simplified further.
Then, we add the 2nd part, -0.5b+1.
We have:
1.8b-0.9-0.5b+1. Next we combine like terms.
1.8b-0.5b = 1.3b.
-0.9+1 = 0.1
Then we put it together.
1.3b+0.1 is our answer.
Hope this helped! Have a nice day :D
Answer:
- 13a - 85
Step-by-step explanation:
Given
- 5a - 86 - 8a + 1 ← collect like terms
= (- 5a - 8a ) + (- 86 + 1)
= - 13a + (- 85)
= - 13a - 85
Answer:
x = 45/13, also x = 3 6/13
Step-by-step explanation:
is = equal sign
of = multiply
<u>Equation:</u>
To do this, you could easily do communitive property of multiplication, but to make it more understandable I will use reversing.
1. Simplify. Multiply - Divide.

2. Factor out common term 5.

3. Multiply both sides by 3.

4. Expand.

5. Add <em>10x</em> to both sides.

Simplify. <em>3x + 10x = 13x.</em>

Divide both sides by 13.

Mixed Number =
.
You can also use distributive property. The formula for this problem is:
.
Are the two middle ones minus or negatives
