2X+2Y=48<br> 3X+Y=40 <br><br> What is X and Y
marshall27 [118]

Answer:

x=8

y=16

Step-by-step explanation:

2x+2y=48

3x+y=40

Ther is many ways to solve this, one of them is clearance:

WE CLEAR AN UNLOCKED (X) AND REPLACE IT IN THE OTHER

x= (40-y)/3

2[(40-y)/3] +2y=48

(80-2y)/3 +2y=48

(80-2y+6y)/3=48

80+4y=48(3)

4y=144

y= 144/4

y=16

x=(40-y)/3

x=(40-16)/3

x=24/3

Question:<br> Image Below
konstantin123 [22]

Answer:

The answer will be: C: 2<em>t </em>+ 10

Step-by-step explanation:

You can check the answer by replacing <em>t </em>with any number.

Example:

I want to find the perimeter for 3 triangles. Here's how I would write the equation.

2(3) + 10 = 6 + 10 = 16

We can check by adding all the sides for three triangles.

2 + 2 + 2 + 5 + 5 = 16

Hope this helped :)
