Answer:

C.   The answer can be simplified.

Step-by-step explanation:

5 2/3 x 3/4

(5 x 3) + 2 = 17/3

17/3 x 3/4 = 51/12

51 ÷ 12 = 4 3/12

4 3/12 = 4 1/4

So it is C.

Hope this helps you!!!!!!!! :D

Answer:

(4, 3)

Step-by-step explanation:

To solve:

First we have to move 3 units right. This means that we have to increase the x axis, because we move left and right on the x axis. This gets you to the coordinates (4, -3).

Now, to move six units up, add 6 to -3. Instead of counting, using the mathematical way makes it easier to calculate. This gets us a y axis point of 3, since the y axis runs from up to down. When we read the final point out loud, this gives us the answer of ...

(4, 3); 4 on the x axis and 3 on the y axis.

Answer:

x = 6

Step-by-step explanation:

you need to solve for x. so you have to get it alone

-1 = x - 7

add 7 to each side

6 = x

Answer:

x = 6

Step-by-step explanation:

Step 1: Flip the equation.

x−7=−1

Step 2: Add 7 to both sides.

x−7+7=−1+7

x=6

The solution is Option C.

The package of 24 ounce is the best buy because the unit rate per ounce is given by the equation C = $ 0.30

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the unit rate of the package = A

a)

A 9-ounce package costs $2.79

So , the cost of 1 ounce = 2.79 / 9

On simplifying the equation , we get

The cost of 1 ounce A = $ 0.31

b)

A 16-ounce package costs $5.12

So , the cost of 1 ounce = 5.12 / 16

On simplifying the equation , we get

The cost of 1 ounce B = $ 0.32

c)

A 24-ounce package costs $7.20

So , the cost of 1 ounce = 7.20 / 24

On simplifying the equation , we get

The cost of 1 ounce C = $ 0.30

Now , $ 0.30 < $ 0.31 < $ 0.32

Hence , the best package is the 24 ounce package which costs $ 7.20

Answer:

A) 14/16

Step-by-step explanation:

To solve 1 3/4 x 2/4, we need to:

Make 1 3/4 an improper fraction:

1 = 4/4, 4/4 + 3/4 = 7/4

Simplify 2/4:

2/4 = 1/2

Multiply Numerators:

7 x 1 = 7

Multiply Denominators:

4 x 2 = 8

Since the answer to 1 3/4 x 2/4 is 7/8, we know that 7/8 = 14/16.

Therefore, your answer is A) 14/16.

Answer:

1st one 1/3( 9+81) goes with 30 since 9 times 1/3 equals 3 and 1/3 times 81 equals 27, 27 +3 is 30

2nd one 0.5(2x +3) goes with x +1.5 since 2x times 0.5 equals 1x or x and 0.5 times 3 equals 1.5, x+1.5

3rd one 2(4x -2) goes with 8x-4 since 4x times 2 is 8 and 2 times -2 is -4, 8x-4

4th one -3( 2/3x-1) goes with -2x +3 since -3 times 2/3 is -2 the demoniator cancels out, and -1 times -3 is 3

5th one -5 (2x+3/5) goes with -10x-3 since -5 times 2x is -10x and 3/5 times -5 is -3 since the demonator cancels out

Answer:

$12,000

Step-by-step explanation:

We have been given that a salesperson works 40 hours per week at a job where he has two options for being paid. Option A is an hourly wage of $25. Option B is a commission rate of 8% on weekly sales.

First of all, we will find the amount earned by the salesperson with option A.

The salespersons earns $1000 through option A.

Let x be the number of weekly sales.  

8% of x should be equal to 1000 for a salesman to earn the same amount with the two options.

Therefore, the salesman needs to make a weekly sales of $12,500 to earn the same amount with two options.

Answer:

21.79

Step-by-step explanation:

use Pythagoras theorem.

50^2 =x^2 + 45^2

2500 =    x^2 + 2025

2500-2025 = x^2

475 = x^2

x = 21.79

Answer:

D. 30 kilometers

Step-by-step explanation:

Add all the given distances relative to the map together:

6.5 + 9.5 + 4 = 20

Multiply that by the scale to convert centimeters to kilometers:

20 x 1.5 = 30

Your answer is 30 kilometers.

You also could have gotten the same answer by multiplying each number by the scale and then adding those together but that is slightly more work so the way I showed is more convenient.
