-9=4+11x+20solve for x.step by step

2 answers:

8 0

So first step: simplify like terms. Since you have two like terms on the same side then you just add them together. Your equation now looks like this: -9=11x+24. Then you subtract 24 from both sides to get -33=11x. Divide both sides by 11(the coefficient of x), and you get -3=x. I hope my steps are clear enough and this is helping you. If you really don’t get it you should ask your teacher. It would really help you.

-9 = 4 + 11x + 20

Combine like terms on the right side of the equation.

-9 = 24 + 11x

Subtract 24 from both sides.

-33 = 11x

Divide both sides by 11.

x = -3

Please Help Evaluate 5c - 3d + 11 when c=7 and d=8

allochka39001 [22]

The answer would be 22.

You would use the order of operations to solve this problem,

First you do the parenthesis, there are none so you skip this

Then the exponents, none so skip it

Then you do multiplication and division from left to right

5•7 is 35, 3•8 is 24

So the problem is now
35-24+11

After multiplication comes addition and subtraction from left to right

35-24 is 11
11+11 = 22

So the answer to (5x7)-(3x8)+11 is 22

Last Month, Levi had written 125 words of his book. This month,he is up to 12,580 words. About how many times more words has he

VladimirAG [237]

Answer:

He has written about 100 times as many words.

Step-by-step explanation:

In order to find this, we first need to find the number that he has written this month. In order to do so, we need to subtract the previous month from the current total.

12,580 - 125 = 12,455

Now that we have that number, we can divide it by the previous month to see how many times more words he wrote in the second month.

12,455/125 = 99.64 times more, or rounded, about 100 times more.

What value will make the equation true? Y + 2 + 6 + Y = 86

g100num [7]

Answer:

Step-by-step explanation:

you need to work backwards

86-2-6=78

therefore, 78 = 2y

y = 2y/2, so 78/2 = 39
