Substitution would be the best method for solving which system?
O x = 6
2x - 3y = 8
3x - 2y = 18
4x + 5y = 60
O x + y = 7
x - 4y = 12
O y = 2x
x + y = 28

Answers

Answer:

The last one

Step-by-step explanation:

Because it tells you what y is

Answer:

Assuming its asking which is the easiest one to use substitution its the last one: y= 2x : x + y = 28

Step-by-step explanation:

Because y and x are already one opposite sides you can substitute y in the 2nd equation with 2x. So you'll get 3x = 28 so x = 9.333333334. Then you plug your answer for x in the original equation to get y = 18.666666667

Relative to Stacy's goal, her average aerobics time over the last five weeks will be 0.09.

What is the average rate change?

It is the average amount by which the function varied per unit throughout that time period. It is calculated using the gradient of the line linking the interval's ends on the graph depicting the function.

Stacy likes to do heart-stimulating exercises 10 hours every week to remain in shape. She tracks how much time she does heart-stimulating exercise every week compared with her goal. The table shows the information throughout the previous five weeks.

The table is given below.

Week                                          1              2            3              4            5

Aerobics time (hours)              2.8          −2           1 ³/₄          0           −3

Then relative to Stacy's goal, her average aerobics time over the last five weeks will be given as

⇒ (2.8 − 2 + 1 ³/₄ + 0 − 3) / 5

⇒ (0.45) / 5

⇒ 0.09

Relative to Stacy's goal, her average aerobics time over the last five weeks will be 0.09.

Find the slope please!

Answers

Answer:  1/2

Explanation:

The two points (0,0) and (2,1) are on the line. Apply the slope formula to them to get the following

m = (y2-y1)/(x2-x1)

m = (1-0)/(2-0)

m = 1/2

This indicates that each time you go up 1 unit, you must move to the right 2 units.

Slope = rise/run = 1/2

Mrs. Davis is building a storage shed that is 12 feet long and 8 feet wide. Construct a scale drawing of the shed. Use a scale of 1/2 inch = 8 feet

Answers

Answer:

3/4 inch by 1/2 inch (length - width)

Step-by-step explanation:

If 1/2 inch equals 8 feet on the scale drawing, this means that 1/4 inch on the scale drawing equals 4 feet, by dividing 2 on both sides.

The storage shed is 12 feet long, and 4 feet on the scale drawing equal 1/4 inch. By multiplying the scale of 1/4 inch = 4 feet by 3 on both sides, we get 3/4 inch = 12 feet. This means that the length of the storage shed can be represented by 3/4 inch.

Since 1/2 inch equals 8 feet and the width of the storage shed is 8 feet, the width can be represented by 1/2 inch on the scale drawing.

Marlo uses 252 lb of gravel to cover a garden plot of 36 ft2. How many pounds of gravel does it take to cover one square foot? How large an area could be covered with 315 lb of gravel?

Answers

The area and the amount of gravel are illustrations of proportions.

7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.

The given parameters are:

[tex]252\ lb= 36ft^2[/tex]

The number of pound for an area of 1 square foot is calculated as follows:

[tex]x = 1ft^2[/tex]

So, we have:

[tex]x = 1ft^2[/tex]

[tex]252\ lb= 36ft^2[/tex]

Cross multiply

[tex]x \times 36 = 252 \times 1[/tex]

Divide both sides by 36

[tex]x = 7lb[/tex]

The area to be covered with 315lb gravel is calculated as follows:

[tex]315lb = y[/tex]

So, we have:

[tex]315lb = y[/tex]

[tex]252\ lb= 36ft^2[/tex]

Cross multiply

[tex]y \times 252 = 36 \times 315[/tex]

[tex]y \times 252 = 11340[/tex]

Divide both sides by 252

[tex]y = 45[/tex]

Hence, 7 lb will cover an area of 1 square foot, while 315 lb will cover an area of 45 square feet.
