Equality Properties

Step-by-step explanation:

<u>Step 1: Define Inequality</u>

3x + 1 < 10

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Subtract 1 on both sides:                    3x < 9
  2. Divide 3 on both sides:                       x < 3

Here we see that any value <em>x</em> smaller than 3 would work as a solution to the inequality.

Please help! :) Need answer fast!

Answer:

x = 3

y = 2

Step-by-step explanation:

When 2 triangles are congruent, they will have exact same 3 sides length and exact same 3 angles measure.

So we can say:

-2x + 6y = 6

and

-7x + 8y = -5

Let's multiply first equation by 7 and 2nd equation by -2, to get:

7 [-2x + 6y = 6] = -14x +42y = 42

and

-2 [-7x + 8y = -5] = 14x - 16y = 10

Now adding these 2 new equations and solving for y:

-14x +42y = 42

14x - 16y = 10

----------------------

26y = 52

y = 52/26

y = 2

Now we put y = 2 into 1st equation (or any other) and solve for x:

-2x + 6y = 6

-2x + 6(2) = 6

-2x + 12 = 6

6 = 2x

x = 6/2

x = 3
