Answer: y= 50

Step-by-step explanation:

The angles that are formed inside the two lines and on opposite sides of the transversal are known as alternate interior angles.

Consider the given figure , we can see that line b and line c are intersected by a transversal so by the definition of alternate interior angles,

The alternate interior angles formed = $y^{\circ}$ and $50^{\circ}$

Since we are given that two parallel lines are crossed by a transversal.

Then the alternative interior angles must be congruent.

$\Rightarrow\ y^{\circ}=50^{\circ}$

Hence, the value of y= 50

Can You Help Me With numbers 6-8

k0ka [10]

Hello,

Your answers and explanations are below.

6 - 5xy

5 times the product of x and y. The product of x and y means to multiply. That is where we get this: xy. 5 times that product is where we add 5 to it and get this: 5xy.

7 - 4x

We get this because we know he gets $4 an hour. We just do not know how many hours he babysat. The hours is X and we multiply that by 4.

8 - 5.5

Take 8.3 and subtract 2.8 to find x. Once we do that we get 5.5, and that is X.

9 - We can't see the problem. It's cut off

Good Luck,

- I.A. -

HELP PLEASEEE!!

Luden [163]

$\left[\begin{array}{ccc}2&6&3\\-5&1&4\end{array}\right]$

R1 ÷ 2 = $\left[\begin{array}{ccc}1&3&1.5\\-5&1&4\end{array}\right]$

R2 ÷ -5 = $\left[\begin{array}{ccc}1&3&1.5\\1&-0.2&-0.8\end{array}\right]$

R2: R1 - R2 = $\left[\begin{array}{ccc}1&3&1.5\\0&3.2&2.3\end{array}\right]$

R2 ÷ 3.2 = $\left[\begin{array}{ccc}1&3&1.5\\0&1&0.71875\end{array}\right]$

R1: R1 - 3R2 = $\left[\begin{array}{ccc}1&0&0.65625\\0&1&0.71875\end{array}\right]$

Answer: x = 0.65625, y = 0.71875

Solve for x - PLEASE NEED HELP, this is my 3rd time posting it.

Answer:

$x=58$

Step-by-step explanation:

First, remember that the maximum degree of an angle totals 360°.

Since we already have 294°, this means that what is left must total $360\textdegree - 294\textdegree= 66\textdegree$ .

Therefore, this means that our two smaller angles must equal 66°. So:

$(36)+(x-28)=66$

Solve for x. Add on the left:

$x+8=66$

Subtract 8 from both sides. Therefore, the value of x is:

$x=58$
