Answer:

x=8

y=13

Step-by-step explanation:

This shape is a parallelogram, and in a parallelogram, the diagonals bisect eachother. So then, you can write to equations:

2x=y+3

x+5=y

This is equal to:

2x-y=3

x-y=-5

Then, you can subtract the two equations, making it:

2x-y=3

-x+y=5

Then the result will be:

x=8

Now that we know what x is, you can find y by plugging it in to either equation.

8-y=-5

-y=-13

y=13

Hope this was helpful!

When you multiply a number by 12 and subtract the product from 360, the difference is 216. Find the number.
tresset_1 [31]

The equation will be 12a – 360 = 216. Then the value of the variable a will be 48.

<h3>What is the solution of the equation?</h3>

The solution of the equation means the value of the unknown or variable.

When you multiply a number by 12 and subtract the product from 360, the difference is 216.

Let the number be a.

Then we have the equation

12a – 360 = 216

By solving the equation, we have

12a = 216 + 360

12a = 576

   a = 576/12

   a = 48

More about the solution of the equation link is given below.

Financial planners recommend that families save about 5% of their take-home pay. Ed and Sherrie save $90 each pay period from th
Ratling [72]

Answer:

Ed and Sheerie save 7.5%.

Step-by-step explanation:

This question can be solved using a rule of three.

Ed and Sherrie save $90 each pay period from their combined paychecks, which total $1200. What percent do Ed and Sherrie save?

How much of $1200 is $90? $1200 is 100% = 1, $90 = x. So

$1200 - 1

$90 - x

1200x = 90

x = \frac{90}{1200}

x = 0.075

Ed and Sheerie save 7.5%.

How do you know what angle degree goes on each corner?
Dahasolnce [82]

Let'sSo, we gave 2 parallel lines and 2 transversals, we have to match the angles.

Let's start with angle b,

\begin{gathered} b+65=180\text{ (angles in a straight line)} \\ b=180-65 \\ b=115^o \end{gathered}

Let's move on to angle e,

\begin{gathered} e=b\text{ (Vertically opposite angles)} \\ \text{but b = 115}^o \\ e=115^o^{} \end{gathered}

Let's move on to angle d,

d=110^o\text{ (V}ertically\text{ opposite angles)}

Moving to angle c, we have;

c=45^o\text{ (Vertically opposite angles)}

And, angle a;

\begin{gathered} a=b\text{ (Alternate angles)} \\ a=115^o \end{gathered}
