What is 37+8x=4(7-x)

Mathematics
1 answer:
nadezda [96]3 years ago
7 0
Simplifying
37 + 8x = 4(7 + -1x)
37 + 8x = (7 * 4 + -1x * 4)
37 + 8x = (28 + -4x)

Solving
37 + 8x = 28 + -4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '4x' to each side of the equation.
37 + 8x + 4x = 28 + -4x + 4x

Combine like terms: 8x + 4x = 12x
37 + 12x = 28 + -4x + 4x

Combine like terms: -4x + 4x = 0
37 + 12x = 28 + 0
37 + 12x = 28

Add '-37' to each side of the equation.
37 + -37 + 12x = 28 + -37

Combine like terms: 37 + -37 = 0
0 + 12x = 28 + -37
12x = 28 + -37

Combine like terms: 28 + -37 = -9
12x = -9

Divide each side by '12'.
x = -0.75

Simplifying
x = -0.75

jack wants to buy the same number of hats for 3 of his friends. he has 57 dollars and each hat cost $5. what is the largest numb
saw5 [17]

Answer: 3

Step-by-step explanation:

You know that he has $57 and 3 friends, so first lets figure out how much money each person gets. To do this, we have to take 57 and divide it by 3. 57÷3= 19.

Now that you know that each person gets $19 and you know that each hat costs $5, all you have to do it divide 19 by 5.

19÷5=3.8.

Since you can't have 0.8 of a hat, each person can only get 3 hats.

I hope this helps. ;)

Hey there! :)

3 - (-2) = ??

Let's keep in mind that a negative times a negative is always a positive!

In addition, let's also remember that parenthesis mean multiplication - so that's how we know that we're multiplying!

So, since a negative times a negative equals a positive, then we know that this question is essentially just asking us what 3 + 2 is!

In case we aren't sure how to do this, let's look at our fingers! We start out with 3 fingers, and add 2 more fingers to it! So, 3 fingers to 2 fingers equals 5 fingers!

Therefore, our answer is 5.

3 -(-2) = 5

~hope I helped~

What is the answer for x? 7/9 - x/9 = 1/3 Please answer ASAP!!!!!
Maksim231197 [3]

Answer:

x=4

Step-by-step explanation:

7/9 - x/9 = 1/3

I like to get rid of fractions so I will multiply each side by 9

9*(7/9 - x/9) = 1/3*9

7 - x = 3

Subtract 7 from each side

7-x-7 = 3-7

-x= -4

Multiply each side by -1

x =4
