My math problem went from 10a+15=65 to 10a+15-15=65-15. Explain what happened in this step.

Answers

Answer 1
You subtracted 15 from both sides so you can isolate 10a.
Answer 2

Answer:

You are subtracting 15 from both side to isolate 10 a it would look like this afterwards:

10a=65-15

And you continue to solve

A rectangular field is 90 yards long and 60 yards wide.Give the length and width of another rectangular field that has the same perimeter but a larger area.

Answers

Answer:

The length and width of another rectangular field with same perimeter but a larger area is 80 m by 70 m

Step-by-step explanation:

The perimeter of the existing field is

2(l + b)

= 2(90 + 60) = 2(150) = 300 yards

So we want another field having the same perimeter but a larger area

The area we have here is 90 * 60 = 5,400 square yards

If we had 80 by 70

Perimeter will still be 2(70 + 80) = 150

But the area will be 80 * 70 = 5,600 square yards

Peter is replacing five broken sections of the picket fence around his house. The length of each section is between 7 and 9 feet, and the height of each section is between 3 and 5 feet. Peter estimates the area of the five sections that need to be replaced to be 200 square feet. Is this a reasonable estimate?

Answers

In this question, we want to evaluate how reasonable is an estimate made by Peter.
To do this, we need to have a range , with the boundaries of the range being the lowest expected area and the highest expected areas respectively.
The lowest expected area would take into recognition the lest length and height which is just 3 by 4 . The area of a section here is thus 3 * 4 = 12 sq.feet
Since there are 5 sections, the total area here is thus 12 * 5 = 60 sq.feet. This is the minimum total area of the sections
For the maximum, we compute the area of the sections using the highest length and height. This is 5 by 6. The area here would be 5 * 6 = 30 sq.feet . Since there are 5 sections, the total area here would be 30 * 5 = 150 sq.feet
Hence, we have the area falling between 60 sq.feet and 150 sq.feet
Since the estimates fall between the boundaries and in fact is closer to the maximum, it is a good estimate

7/2

Step-by-step explanation:

Firstly lets put them all in common denominators (LCM) 3,2,4 and 8 re all divided by 24.

17/8 x 3/3 = 51/24

7/2 x 12/12 = 84/24

9/4 x 6/6=54/24

10/3 x 8/8= 80/24

Now lets see which one is greatest: 7/2 or 84/24

Answers

Answer:

5 sessions

Step-by-step explanation:

For this problem, we will simply take the total cost for each gym and set them equal to each other with the missing amount of sessions represented as x.

25 + 30x = 75 + 20x

Now, we will solve for x to find how many sessions it would take for these two total costs to be equal.

25 + 30x = 75 + 20x

10x = 50

x = 5

So after 5 sessions, Ms. Pictum will have spent the same amount at both gyms.

What is the equation of the line that passes through the point (2,−1) and has a slope of 3/2

Answers

Answer:

y=3/2x-4

This is the answer.

Given :-

A line having a slope of 3/2 passes through (2,-1) .

To Find :-

The equation of the line .

Answer :-

According to the question ,

m = 3/2

Point = (2,-1)

We know Point slope form of the line as ,

y - y¡ = m ( x - x ¡ )

Substitute ,

y - (-1) = 3/2 ( x - 2 )

y + 1 = 3/2x - 3/2*2

y +1 = 3/2x - 3

2( y +1) = 3/2x *2 - 3*2

2y + 2 = 3x - 6
