56/-2=-2

Answer:

I think it is D!

Step-by-step explanation:

I'm not exactly for sure so if I'm wrong I'm sorry! But when writing an equation they don't have + or - and my conclusion is if you divide 750 by 3 it equal out to be 250 per minute. But I'm not for sure:(

Answer:

1)13/3 2)-1/2 3)5/6

Step-by-step explanation:

1) Determine the sign(since there is 2 negatives it turns positive)

Then you simplify the complex fraction to 4/3+3

Then you calculate

2) Determine the signs you get to -6+4/-1+5

calculate -2/4

then solve

3) multiply everything to get 8-(5+(-12))/16+2

Then you calculate 8-(5-12)/18

Calculate again8-(-7)/18

Answer:

Number 2

Step-by-step explanation:

The reason is because you are multiplying 10 by 5 and three this what it would look like

10(5+3)

10( Times) 5= 50

10(times) 3 = 30

50+30

Answer: I think the answer would be 10( 5 + 3)

Step-by-step explanation:

first you add 5 and 3 together and you get 8

the multiply 8 times 10

and you get 80

And lastly to check your answer you add 50+30 together and u also get 80

Answer:

You would go 1/4 of the 1 then you would go to 2 and there you go.

Step-by-step explanation:

Answer:  these are in "slope-intercept form"  y = mx + b

m is the slope.  b is the y-intercept

Start with the y- intercept, the "constant" on the right side of the equation. Plot a point there on the y-axis. Then use the slope to plot another point or two to find our where to draw the line. If there is no number for m, it is an implied 1. That means from your first point, go up 1 then 1 to the right to plot the next point

Step-by-step explanation:

When the slope is a fraction, use the denominator to find out how far to go to the right.

If the slope is negative, move down first then to the right to plot the next point.

Answer:

100 boxes are packed in 4 minutes

Step-by-step explanation:

If you take a look at the graph, for example, y equals 50 and x equals 2, which means that the constant of proportionality is 25. 25 x 4 = 100

Answer:

The answer is 1620 seedlings.

Step-by-step explanation:

The rate is that every one week, there is an increase of 324 seedlings. If it continued for 5 weeks, the total amount of seedlings will be 1620 seedlings. The equations I used to solve this are 648-324=324. 324x5=1620.

Step-by-step explanation:

Amanda makes 45 biscuits in 30 minutes which is determined by the ratio.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that Amanda makes 3 biscuits in 2 minutes.

Let the number of biscuits would be x

To determine the number of biscuits can she make in 30 minutes.

According to the given question, we can write the ratio as:

3 biscuits : 2 minutes = x biscuits : 30 minutes

⇒ 3 / 2 = x / 30

Apply the cross-multiplication operation

⇒ x = (30 × 3) / 2

Apply the multiplication operation

⇒ x = 90 / 2

Apply the division operation,

⇒ x = 45

Therefore, she makes 45 biscuits in 30 minutes.

#SPJ2

Answer:

48 professors

Step-by-step explanation:

First, add 11 + 6 = 17

Here is what I did after that,

136 / 17 = 8

I divided 136 by 17 because for every 11 lecturers there are 6 professors, and to get the total amount of how many times there are 6 professors and 11 lecturers.

After that, you would multiply 8 * 6, since there are 6 professors.

So, the answer that I got would be 48.

Hope this helps :)

Answer:

7 (w-6)

Step-by-step explanation:

I dont know if there is any more answers

Answer:

-6 is the slope

Step-by-step explanation:

In order to find the slope you need to do put it in slope intercept form

y2-y1/x2-x1 is slope-intercept  form

(-7 - (-1))/4-3 = (-7 +1)/1 = -6/1 = -6

Answer:

The slope in -2

Step-by-step explanation:

to graph this use the slope-intercept form of y=-2x+1

Answer: The first and third choices are deductions that Mr. Davis can make from the data displayed.

Step-by-step explanation:  The last choice is partly true. The highjest individual score was a student in third period, but most schools consider failing to be somewhere below 60 to 67%. There are several of scores below those numbers. The dots at the left end are "outliers."  

The second choice may be true, but the data is about the scores on the test, not the number of students in the classes.
