Answer:

5x - 4 = 56

2x + 3 = 27

Step-by-step explanation:

2(5x - 4 + 2x + 3) = 166

10x - 8 + 4x + 6 = 166

14x - 2 = 166

     + 2     +2

14x = 168

divide both sides of the equal sign by 14

12

5(12) - 4 = 60 - 4 = 56

2(12) + 3 = 24 + 3 = 27

A salesperson is paid a base salary of $300 a week plus a 5% commission on the sales he generates. Which inequality best represe
Damm [24]
The expression can be written as the inequality:

300+0.05s≥500

300$ is made per week, so we start off with

300

He also makes 5% or 0.05 from his sales, so we add in the expression 0.05x (where s is equal to his sales volume for the week)

300+0.05s

If he wants to make at least 500$ weekly, then the total of the base salary plus the commission has to be 'greater than or equal to 500.

300+0.05s≥500

Lets solve for s now...

300+0.05s≥500
subtract 300 from both sides
0.05s≥200
Divide both sides by 0.05
s≥4000

A. Y would be 14 since 2w would equal -8, and -8+14=6.
B. Y would be -14 because 2w would equal 20 and 20+(-14)=6

What is value of the digit 5 in the number 75
ycow [4]
First, think of your places. You have the ones places, tens places, hundreds places, and so on. 

The first number starting from the right is the ones, and as you keep going left, the value of each given digit becomes higher.

Since 5 is in the ones place, its value would be just 5. If it were in the tens place, it would be 50. If it were in the hundreds place, it would be 500, and so on. 

Think of it this way;

Ones is just one. If a number is in the 'ones' place, its value would be a single digit. If it were in the tens place, its value would be two digits. 
That's how it would be for each place going left. 
Every number you move to the left, its value gains a one.

So here's an example: 
5555

The value of 5 in the ones place "5555" is simply 5.

In the tens place, you end up adding one zero, so the value of the second five to the left would be, "50"

So with that said, the value of the digit 5 in the number 75 is <em>5.

</em>
Haha, hope this cleared up any confusion, and have a <em>wonderful </em>day! :)<em>

The big rectangle has a base of 16 and a height of 7 (subtract 12-5=7 for height) Multiply base*height to get area of big rectangle:

16*7 = 112 in

The small rectangle has a base of 10 and a height of 5. Mulitply base*height to get area of small rectangle:

10*5 = 50 in
