Answer:

Nancy fits the equation.

Step-by-step explanation:

I think they're asking which gorilla fits the equation.

2b - 15 = 605

<em>Add 15 to both sides</em>

2b=620

<em>Divide both sides by 2</em>

b=310

The only gorilla who weighs 310 pounds is Nancy.

An office supply company sells two types of fax

Phantasy [73]

14 of the machine that cost $150 was sold and 8 of the machine that cost $225 was sold.

To solve this problem, we would write a system of linear equations.

Let x represent the machine that cost $150

Let y represent the machine that cost $225

We can proceed to write our equations now.

$x + y = 22...equation(i)\\150x + 225y = 3900...equation(ii)$

From equation 1

$x+ y = 22\\x = 22 - y...equation (iii)$

<h3>The Value of Y</h3>

put equation (iii) into (ii)

$150x + 225y =3900\\x = 22-y\\150(22-y)+225y=3900\\3300-150y+225y=3900\\3300+75y=3900\\75y=3900-3300\\75y=600\\75y/75=600/75\\y=8$

<h3>The Value of X</h3>

Since we know the number of y, we can simply substitute it into equation (i) and solve.

$x + y = 22\\x + 8 = 22\\x = 22-8\\x = 14$

From the calculations above, 14 of the machine that cost $150 was sold and 8 of the machine that cost $255 was sold.

Sandra is a real estate agent and rams 5000 commission on the selling of a 62,000 house. what is the percent of commission she r

sveta [45]

To find a percent, you use this simple formula:
5000/62000 = x/100

In this case, x is going to be your percent of commission.

So, to find this, you first divide 5000 by 62000, which is about equal to 0.08.

Now your equation looks like this:
0.08 = x/100

Next, you multiply both sides by 100 to reverse the operation. Now, your equation will look like this:

8 = x

So, the answer is 8%.
