Substiute<br> y=3x-15 <br>4x+2y=22
Nostrana [21]
You can solve it by replacing the Y in the 2nd equation with the solved Y in the first.

4x + 2(3x-15)= 22

that should give you...

4x + 6x - 30 = 22

then combine like terms...

10x - 30 = 22

now we need to get X alone so add 30 to each side....

10x = 52

now divide both sides by 10..
X = 52\10

both are divisible by 2...

X = 26\5

you should be done unless you need Y as well then go back to the first and plug in what you found for X...

Y = 3(26÷5)- 15

and that should give you Y.

a 2nd method you can make your own answer by making x = 0 ..

Y= 3(0) -15

Y= -15

now put that in the 2nd for Y...

4x+ 2(-15) = 22...

4x-30= 22

add 30 to both sides..

4x = 52

divide by 4....

X = 13

now take this to the first for x...

Y= 3(15) - 15

Y = 30

you can check your work by plugging in the two on top and see if the final is the same..

30 = 3(15) - 15

the 2nd way is faster though of course..

anyway X= 13 Y= 30

The Jones Company buys $1,500 worth of goods from the Acme Corporation on credit with a provision of 2.5/10, net 30. The Jones C
Zolol [24]
The '2.5/10' part means a 2.5% discount is available if paid within 10 days. (2.5% = 0.025) 
Amount of the discount: 
($1,500 x 0.025) = $37.50 
Amount needed to pay within 10 days is ($1,500 - $37.50) = $1,462.50

hope it helps

2. The variable expressions represent the angle measures of a triangle. Find the measure of each angle. Then classify the triang
Umnica [9.8K]

Answer:

Step-by-step explanation:

The triangle KLM is shown in the attached photo. The sum of the angles in a triangle is 180 degrees. It means that

angle K + angle L + angle M = 180 degrees. Since

m angle K=(10x+10). m angle L=(9x-3). m angle M=(7x-9), then

10x + 10 + 9x - 3 + 7x - 9 = 180

10x + 9x + 7x = 180 + 9 + 3 - 10

26x = 182

x = 182/26

x = 7

m angle K=(10x+10) = 10×7 + 10 = 80 degrees

m angle L=(9x-3) = 9×7 - 3 = 60 degrees

m angle M=(7x-9) = 7×7 - 9 = 40 degrees.

The triangle is an acute triangle because each angle is lesser than 90 degrees

The triangle is scalene triangle because non of the sides are equal.

If they have 362 roles of wrapping paper and they sold 4,706$ of wrapping paper how much was one role?
Ivenika [448]

Answer: $13

Step-by-step explanation:

From the question, we divide the number of 362 roles by the amount sold.

That is if 362 roles = $4706

1 role = $4706/362 = $13

1 role costs $13

I hope this helps, please mark as brainliest.
