Please help me for algebra
In-s [12.5K]
Step by step solution:

The clothes are hung on the middle so the angles opposite to angle x is equal....1)

As we know that the sum of all the angles is 180°

let us take angle y which is opposite to angle x

Therefore,
angle x + angle y + 158°= 180°
2 angle x + 158°=180°(by 1)
2 angle x = 180°-158°
2 angle x = 22°
angle x = 22/2
angle x = 11°

Hope it helps you....

Find the value of y in parallelogram QRST.
Arturiano [62]
<h2>Answer:</h2>

y = 5

<h2>Step-by-step explanation:</h2>

<em>Solution:</em>

7y = 5y + 10

7y - 5y = 10

2y = 10

\frac{2y}{2} = \frac{10}{2}

y = 5

<em>Checking:</em>

7y - 5y = 10

7(5) - 5(5) = 10

35 - 25 = 10 ✓

Micky is trying to solve the following problem but, he missed the lesson. In complete sentences, describe how you woukd solve th
frez [133]
We must solve for x.  Let's simplify this equation by dividing both sides by 6:

|2x-14|=7, which is the same as 2|x-7|=7.

First, assume that x-7 is already positive, so that we don't need the absolute value operator.  Then x-7=7/2.  Adding 7 to both sides results in x = 21/2.

Next, find the other solution:

Assume that x-7 is negative.  Then |x-7|=-(x-7).  Then -(x-7) = 7,

and -x + 7 = 7.  Thus, x = 0.

The solution set is {0, 21/2}.
