a) 3x + 5y =  26  

b) 2x + 2y = 12

First, we need to find a way to equate either the x terms or the y terms in each equation. a)  6x + 10y = 52

                          b) 6x + 6y = 36

Then take equation b) from the equation a) to eliminate the x component.

a) 6x + 10y = 52

- b) 6x + 6y = 36

   0x    + 4y = 16

            y = 4 ?

Then substitute the value of y into either equation to find the value of x.

b) 2x + 2y = 12

   2x + (2x4) =12

   2x + 8 = 12

   2x = 4

   x = 2

I hope this new information i read helps you maybe understand it and as an example!

A triangle has a 90° angle, and the other two interior angles are congruent. Explain how to find the measure of one of the two c
Salsk061 [2.6K]

Answer:

45 degrees

Step-by-step explanation:

Think of it like this the sum of the angles in a triangle are the always the same 180 degrees.

So now, we do 180 - 90 = 90 this is the sum of the other angles.

We shall assume that they are the same and divide 90/2 = 45 degrees each

Ok here are some things to understand while solving!

  • If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.
  • If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
  • If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
  • If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
  • If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.
  • Without knowing at least one side, we can't be sure if two triangles are congruent. (which we do!)

Hope this helped!

Study hard!

Find c to complete the perfect trinomial<br><br> x2 + 4x + c
sladkih [1.3K]

Answer:

4

Step-by-step explanation:

I assume that is supposed to be x squared. A perfect trinomial is the product of a perfect square, (x times a number) squared. With these trinomials, you can look at them as: ax squared times bx + c. When a is 1, the fastest way to get c to make a perfect square is to divide b by 2. In this case, it's 4/2 = 2. The last step is to square that number. 2 squared = 4.
