Answer:

A) on edge2020

Step-by-step explanation:

The greatest amount of time when they worked together is 2.4 hours.

Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.

Given:

Randy at most 4 hours to clean the offices.

Trey at most 6 hours to clean the offices.

If they work together, they will clean

1/4 + 1/6 = 5/12 of the offices.

Let x be the greatest amount of time it would take them to clean the offices together.

Thus,

5*x/12=1

5x=12

x= 12/5

x= 2.4 hours.

Answer:

37/6

Step-by-step explanation:

The improper fraction is 37/6.

What is improper fraction?

An improper fraction is defined as a fraction whose numerator is greater than the denominator. Suppose, x/y is an improper fraction, such that x > y. It is therefore, the improper fraction is always greater than one.

Fractions have two parts, numerator and denominator. If  ⅓ is a fraction, then 1 is the numerator, and 3 is the denominator. An improper fraction has a numerator greater than the denominator. For example, 3/2 is an improper fraction.

Given fraction is [tex]6\frac{1}{6}[/tex]

firstly we will multiply 6 by 6 and then we will add 1

(36+1)/6

= 37/6

Which is improper fraction.

Answer: Slope = -7/5

=========================================================

Explanation:

Pick any two rows you want. I'll select the first two rows.

Each row represents an (x,y) point

The first row means (-8,55) is one point and the second row means (2,41) is another point.

Use these two points in the slope formula to get

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

m = (41-55)/(2- (-8) )

m = (41-55)/(2 + 8)

m = -14/10

m = -7/5 is the slope

The negative slope means the line goes downhill as you move from left to right.

Specifically, every time it drops 7 units the line moves over to the right 5 units.

slope = rise/run = -7/5

rise = -7, negative rise means we go down 7 spaces

run = 5 means we move to the right 5 spaces

For A, the answer is D, y=-x+2, and for B, the answer is C, (2,1)

Step-by-step explanation:

The answer for question A is justified by the fact that the graph is negative, so x is -x, but there is a positive y-intercept so it is a +2 y-intercept. For question B, I just graphed it on desmos and looked for all the points , and (2,1) is the only one on the line.

Answer:

Yes, we agree with her prediction.

Step-by-step explanation:

Given:

Number of sample student = 60

Number of total student = 600

Number of student plan to go college = 675

Sample of student plan to go college = 75%

Find:

Prediction is correct or not

Computation:

Number of student plan to go college in sample = 60 × 75%

Number of student plan to go college in sample = 45

Number of student plan to go college = Number of student plan to go college in sample [900 / 60]

Number of student plan to go college = 45[900 / 60]

Number of student plan to go college = 45[15]

Number of student plan to go college = 675

So,

Yes, we agree with her prediction.

Answer:

x = 53

Step-by-step explanation:

22 - 3 ( x - 70 ) = x + 20 Multiply out

22 - 3x + 210 = x + 20

22 + 210 - 3x = x + 20

232 - 3x = x + 20

232 - 3x + 3x = x + 3x + 20

232 = 4x + 20

232 - 20 = 4x + 20 - 20

212 = 4x

212/4 = 4x/4

212/4 = x

x = 53

Answer:

Step-by-step explanation:22-3(x-70)=x+20

22-3x+210=x+20

22+210-3x+3x=x+3x+20

232=4x+20

4x=232-20

X=53
