matt has answered 20 of 25 of the questions on a test. what percentage of the test questions has matt answered

Answers

The percentage of questions Matt has answered is 80 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Number of questions Matt has answered = 20

Total number of questions = 25

Let the percentage of questions Matt has answered = x


Number of questions Matt has answered / Total number of questions = x %

Percentage of questions Matt has answered = ( Number of questions Matt has answered / Total number of questions ) / 100

                                                                    x    = ( 20 x 100 ) / 25

                                                                    x    = 20 x 4

                                                                    x    = 80 %

Hence, the percentage of questions Matt has answered is 80 %

A track is 200 meters long. How many times must Julius run around the track to run 3 kilometers ?

Answers


Here is how you would do this: If there are 1000 meters in one kilometer, and you know that this track is 200 meters long, then you can find how many times Julius must run around the track in order to reach ONE kilometer:

1000 meters / 200 meters = 5 times in around the track for ONE kilometer.

To find how many times Julius would need to run around to reach THREE kilometers you simply do the following:

5 x 3 = 15 ---> Julius would need to run around the track 15 times in order to reach 3 kilometers.

2x +3y =12 Dan 3x-1y=7

Answers

2x+3y=12
3x-y=7

use subsituttion
make one of the equations equal to a placeholder
3x-y=7
subtract 7
3x-7-y=0
add y
3x-7=y
subsisute 3x-7 for y in first equation

2x+3(3x-7)=12
2x+9x-21=12
11x-21=12
add 21 to both sides
11x=33
divide both sides by 11
x=3

subsitute x for 3 in any equation
3x-7=y
3(3)-7=y
9-7=
2=y


x=3
y=2
2x+3y=12
3y=-2x+12
y=-2x/3+4

3x-1y=7
-1y=-3x+7
y=3x-7
