Solve by using elimination. Express your answer as an Ordered pair (-x +2y=3 3x-2y=7

Answers

Answer:

(5,4)

Step-by-step explanation:

-x+2y=3

3x-2y=7

Add the like terms( 2y and -2y)(-x and 3x)(3 and 7) together. Do this vertically. 2y and -2y cancel eachother out.

2x=10

Divide both sides by 2

x=5

To find y, substitute x in for y in one of the equations

-5+2y=3

add 5 to both sides

2y=8

Divide both sides by 2

y=4

Check:

-5+2(4)=33=3

TRUE or FALSE: If the variable is by itself, then it is understood to have a 1
as its coefficient.

Answers

When a variable is by itself the coefficient is 1

Answer:

True

Step-by-step explanation:

The same goes for denominators. If there is a whole number, decimal, or variable without a denominator, you can automatically say that the denominator is 1. Because a number multiplied or divided by 1 stays the same.

You need to find the WPM (words per minute) of each person.

Andre - 208 divided by 4 = 52

Noah - 342 divided by 6 = 57

You now know that Andre types 52 words per minute and Noah types 57 words per minute.

Answer: Noah types faster because he types 57 words per minute while Andre types 52 words per minute.

Answer:Noah types faster.

Step-by-step explanation: For Andre ,You do 208 divide 4 which gives you 52.For Noah, you do 342 divide by 6 which gives you 57.And since Noah  type more words which is 57  while Andre type 52, that means Noah types faster.
