Multiplication word problems arise in situations where we do repeated addition of the same number. Think of multiplication as a shortcut for adding the same number multiple times.

Answer:

B. $\frac{60 hours}{1} \times \frac{1 day}{24 hours}$

Step-by-step explanation:

Converting 60 hours to days:

24 hours = 1 day

60 hours = x day

Cross multiply

$24 hours \times x = 60 hours \times 1 day$

Divide both sides by 24 hours

$x = \frac{60 hours \times 1 day}{24 hours}$

Thus,

$\frac{60 hours \times 1 day}{24 hours} = \frac{60 hours}{1} \times \frac{1 day}{24 hours}$

The expression that shows how to convert 60 hours to days is:

$\frac{60 hours}{1} \times \frac{1 day}{24 hours}$

Answer:

x = 7, -7

Step-by-step explanation:

(2x-1)(3x+2)+x+292

3x - 2x +x = 2 - 1 + 292

(6)x - 294 = 6(x - 49)

Use communicative property of multiplication

Example: (A+B)(A-B)

$Ax^{2} -AB+BA-Bx^{2} =Ax^{2} -AB+AB-Bx^{2} =\\Ax^{2} -Bx^{2}$

49 is the square of 7

x square is the square of x to the power of 1

On a piece of paper, graph this system of inequalities. Then determine which region contains the solution to the system.

Mashutka [201]

we have

$y\leq \frac{1}{4}x+3$ ----> inequality 1

The solution of the inequality 1 is the shaded area below the solid red line

The solution is the region D and region C

$y\geq-x+5$ -----> inequality 2

The solution of the inequality 2 is the shaded area above the solid blue line

The solution is the region B and region C

The solution of the system is the common area

The solution is the region C

see the attached figure

therefore

the answer is the option C

Region C

Part A: Consider the equation x + 7 = 16. Which number from the set {5, 7, 9, 11} makes the equation true?

wel

Part A: Substitute/plug in each number into the equation to see which number will make the equation true.

x + 7 = 16 Plug in 5 into "x"

5 + 7 = 16

12 = 16 5 doesn't make the equation true because it equals 12 not 16

x + 7 = 16 Plug in 7 into "x"

7 + 7 = 16

14 = 16 7 doesn't make the equation true because it equals 14 not 16

x + 7 = 16 Plug in 9 into "x"

9 + 7 = 16

16 = 16 9 makes the equation true because it equals 16

Part B: Plug in 9 into "x" in the inequality to see if it still makes it true.

x + 7 < 16 [x plus 7 is less than 16]

9 + 7 < 16

16 < 16 [16 is less than 16] The same number would not make the inequality true because 16 can't be less than itself.

To figure out which numbers satisfy the inequality, plug it into the inequality:

x + 7 < 16 Plug in 5 into "x"

5 + 7 < 16

12 < 16 5 does satisfy the inequality because 12 is less than 16

x + 7 < 16 Plug in 7 into "x"

14 < 16 7 does satisfy the inequality because 14 is less than 16

x + 7 < 16 Plug in 11 into "x"

11 + 7 < 16

18 < 16 11 doesn't satisfy the inequality because 18 isn't less than 16
