Answer:

I will do a step by step explanation to help you.

First, subtract 16 from 31 so you can simplify what you need to find. We will call the unknown number X. So 5x = 15

15/5 = 3 so X = 3

Lets plug in X

3 x 5 + 16 = 31

Makes sense!

Hope this helps

Answer:

Step-by-step explanation:

So first, we'll have to do a quick equation.

31 - 16 = 15

Now, we can divide 15 by 5.

15 ÷ 5 = 3

So now we know that the sum of 5 times a number and 16 is 3 because:

3 x 5 = 15

15 + 16 = 31

So therefore, your answer is 3.

After the fraction x plus 1 all over 2 minus the fraction x plus 2 all over 3 x have been combined using the least common denomi

RoseWind [281]

If I've read this correctly, it looks like this.

$\dfrac{(x + 1)}{2 - \dfrac{(x + 2)}{3x}}$

If that is correct, then the first step is to put the top part of the denominator over 3x

$\dfrac{(x + 1)}{\dfrac{6x - (x + 2)}{3x}} = \dfrac{(x + 1)}{\dfrac{5x -2}{3x}}$

The next part is to flip a three tier fraction. I'm afraid I have to show what happens. My latex is not that strong.

What you get is

$\dfrac{3x*(x + 1)}{(5x - 2)}$

This is just about your final answer. You could write it as

$\dfrac{3x^2 + 3x}{(5x - 2)}$

You have decided to purchase a car for $22,346. 16. The credit union requires a 10% down payment and will finance the balance wi

Natali [406]

The amount that the credit union will finance is $24169.60

We have given that the cost of the car is $22,346. 16

and the credit union required 10% down payment

and sale tax=7.6%

The license and title charges are $125. 13.

We have to determine that the amount that the credit union will

finance Now we have sale tax 7.6% for $22,346. 16

Therefore, we get

$\frac{7.6}{100} \times 22,346. 16=1698.31$

<h3>What is the amount that the credit union finance ?</h3>

credit union finance=cost of car+sales tax+the license and title charges.

$=22346.16+1698.31+12.13\\=24169.60$

Therefore, the amount that the credit union will finance is $24169.60

A woman bought some large frames for $18 each and some small frames for $8 each at a closeout sale. If she bought 21 frames fo

IrinaVladis [17]

Answer:

8 large frames and 13 small frames

Step-by-step explanation:

Given:
$18 each = large frames

$8 each = small frames

To Find:

⇒ Bought 21 frames for $248, find how many of each type she bought

Solve:

1 Large frame costs = 18 $

Therefore, x large frames costs = 18x $

{where x is the number of large frames she bought}

1 Small frame costs = 8 $

Therefore, x Small frames costs = 8y $

{where y is the number of small frames she bought}

By the given condition :

18x + 8y = 248 {equation 1}

x + y = 21 {equation 2}

Solve these equations simultaneously, from second equation we get :

x = 21- y

18⋅(21−y)+8y= 248

378 - 18y+8y = 248

-10y = -130

y = 13

Put y = 13 in eq x = 21- y

x = 21 - y

x = 21 - 13

x = 8

So the woman bought 8 large frames and 13 small frames.
