ANTONII [103]3 years ago
3 0

Answer:

If my memory serves me correctly, then you just have to multiply the variable 3 by whatever number you are facorting it by, in this case 6 and 3.

So, the answer would be y = 18x

Solve, using linear combination. <br> 5x + y = 2 <br> 4x + y = 4
Jet001 [13]
5x+y=2
4x+y=4

5x+y=2
-1( 4x+y=2)

5x+y=2
-4x-y=2

your y'all cancel out so you r left with

x=-2
then you plug the x in to one of the equations
5(-2)+y=2
-10+y=2
then add 10 to both sides
y=12

Answer: x = -2 y = 12

there's the work and all its simple you just have to figure out how to get rid of y or x ( which ever is easier) and you can figure it out after that

If 25 students took an exam and 4 of them failed, what percent of them passed?
lisabon 2012 [21]

If 25 students took an exam and 4 of the students that took the exam failed, what percent of the students passed?

To find out how many students passed, we can subtract 4 from 25 and we will get a difference of 21.

The fraction \frac{21}{25} represents the number of students who passed the exam out of all the students.

To find out what percent of the students passed, we can turn \frac{21}{25} into a percent.

21 ÷ 25 = 0.84

0.84 × 100 = 84%

Therefore, 84% of the students who took the exam passed.
