Answer:

x=12, y=30

Step-by-step explanation:

to find x:

in a equilateral triangle, all three sides are congruent, so:

4x-4=3x+8

x-4=8

x=12

to find y:

in an equilateral triangle, all the angles are 60°, so:

2y=60

y=30°

X + 2y = 7<br> 3x - 2y = -3

Use Subtraction

1. Subtract
x+2y=7
3x-2y=-3
-------------
4x+0y=4 SIMPLIFY 4x=4

2. DIVIDE

4x=4
x=1

Substitute that into either of the original equations to get x=1, y=3

jenny is comparing the cost of two packages of socks. one package has 8 pairs for $12. Another package has 3 for $6. Are the rat

Ainat [17]

In order to solve this we need to make on part of both statements equal.

Since 12 is divisible by 6 lets do that.

Multiply everything in the second package by 2.

It then becomes 6 pairs for $12.

So now have have 6 or 8 pairs for $12.

You are getting a different amount for the same price therefore they are not proportional.
