Answer:

Just to help you out in how to solve this just plug in every x of an equation -6, and in every y, -1. Plug these two number in every equation and see if it equal each other.Example:

y =4x +23

-1 = 4(-6) + 23

-1 = -24 + 23

-1 = -1

it shows that (-6,-1) is a solution to this equation

Letter A is one answer, let's see if you can find the others

the three sides of a triangle are n, 3n+2, and 4n−4. If the perimeter of the triangle is 54cm, what is the length of each side?
taurus [48]

The lengths of the sides are 7, 23 and 24.

In order to find this, we need to add all of the side lengths together and set equa to 54. This will allow us to solve for n.

n + 3n + 2 + 4n - 4 = 52

8n - 2 = 52

8n = 54

n = 7

This gives us the length of the first side. To solve for the others, plug 7 into the equations.

3n + 2

3(7) + 2

21 + 2

23

Then the next one.

4n - 4

4(7) - 4

28 - 4

24

Using appropriate properties find: <br> 6/5 × -5/7 -3/4 -5/7 × 4/5​
VARVARA [1.3K]

Answer:

1 and 4/35

Step-by-step explanation:

Use distribution property to solve:

6/5 × -5/7 -3/4 -5/7 × 4/5​ = -5/7 ( 6/5 - 3/4 ) x 4/5 = -5/7 ( 24/20 - 15/20 ) x 4/5 = -5/7 (-39/20) x 4/5 = 780 / 700 = 1 4/35
