Simplify the expression: 2(5a - 4a ) + 6a
miv72 [106K]

Hello from MrBillDoesMath!

 

Answer:     8a

Discussion :

Let's study the expression:

2(5a - 4a) + 6a

The boldfaced term simplifies to "a"  as 5 = 4 = 1. So the expression becomes

2a + 6a

As 2 + 6 = 8,  2a +  6a = 8a.

Four more than a number is more than 13
Pepsi [2]
X > 9 is the answer. This is the correct answer because you would subtract 4 from each side of the equation, which would leave X on one side and nine on the other. The inequality remains the same since you are not dividing at all by any negative numbers

How do you do this?? <br> explain it well please!
Nesterboy [21]
First you want to combine like terms. on the first equation we can combine 2x+x=3x. So now we have 3x-3. On the right side we can combine 12+1 so we now have -x+13. Now we will take add an x to -x so it's 0 but we have to do it to the other side as well so now we have 4x-3=13. now we will add three to -3 to make it 0 but again we have to do it to the other side. Now we have 4x=16. We want to figure out what x is so we now divide 4x by 4 so we are just left with x but we need to do it to the other side so your answer is x=4
