Answer:

(17-3)/2=7 games

Step-by-step explanation:

So she paid $3 for shoes so we can take away $3 from $17 then we can take that answer and divide it by 2 (because it is $2 per game) and we will get our answer. The equation would be:

(17-3)/2

17-3 is in () because we have to do that first and parenthesis are the p in order of operations (pemdas). Now to solve:

parenthesis first:

(17-3)/2=

14/2=

Mr. Stein is purchasing a 2.25 pounds of meat that cost $2.80 per pound. How much will he receive if he pays the cashier $20.00

antoniya [11.8K]

He will receive $13.70.

You would have to multiply 2.25 by 2.80 to get 6.30, which is the total cost due. Subtract 6.30 from 20 to get your answer, 13.70, or the change Mr. Stein will receive.

Find the domain of each function using interval notation. (Please help I have an exam tomorrow and I’m really stuck)

stellarik [79]

Answer:

For number 9)

Interval notation $(-\infty,3]$

For number 10)

Interval notation: $(-\infty,\frac{-1}{2}) \cup (\frac{-1}{2},\infty)$ .

Step-by-step explanation:

On square roots you have to make sure the inside is positive or zero.

So the domain of the first one will come from solving

$6-2x \ge 0$

Subtract 6 on both sides:

$-2x \ge -6$

Divide both sides by -2 (flip inequality when divide both sides by negative):

$x \le 3$

The domain is less than or equal to 3.

Interval notation $(-\infty,3]$

On fractions you have to watch out for dividing by 0.

The domain is all real numbers except when 4x+2=0.

4x+2=0

Subtract 2 on both sides:

4x=-2

Divide both sides by 4:

x=-2/4

Reduce:

x=-1/2

The domain is all real numbers except when x=-1/2

Interval notation: $(-\infty,\frac{-1}{2}) \cup (\frac{-1}{2},\infty)$ .

Which of the following statements explains how to solve for l using the formula A = lw, when A = 28 and w = 2? Divide 28 by 2. D

igor_vitrenko [27]

Answer:

Divide 28 by 2

Step-by-step explanation:

When the variable of interest is multiplied by something, you undo that multiplication by dividing the equation by that something.

Here, l is multiplied by 2, so the solution is found by dividing ...

... 28 = l·2

by 2 to get ...

... 28/2 = l

That is, you divide 28 by 2 to find l.
