Answer:

x = 21

General Formulas and Concepts:

<u>Geometry</u>

  • Corresponding Angles - Angles that are congruent to each other and occur with parallel lines

Step-by-step explanation:

<u>Step 1: Identify</u>

We see that the measures given are Corresponding Angles

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

  1. Set up equation:                         8x - 7 = 9x - 28
  2. Subtract 8x on both sides:         -7 = x - 28
  3. Add 28 on both sides:               21 = x
  4. Rewrite:                                       x = 21

Emily and Sarah had a total of $80. after Sarah spent 1/3 of her money and Emily spent $17, Emily had twice as much money as Sar
Phoenix [80]
<span> SO in total, Emily and Sarah had a total of 80 dollars in which Emily had twice as much as Sarah.
Let’s solve to find out how much their Money is.
=> Since the ratio of the given data is 2:1, 2 + 1 =3, so let’s divide 80 by 3
=> 80 / 3 = 26.667 ,
=> Emily has twice as this.
=> 26.667 * 2 = 53.33
=> Sarah has 26.67
Now, Sarah spent 1/3 of her money
=> 26.67 / 3 = 8.89 – her remaining money
Emily spent 17 dollars of her money
=> 53.33 – 17 = 36.33</span>

How do you solve the math equation
GalinKa [24]
First of its y-y1 = m(x-x1)
m is the slope, what it is increasing by. 
y1 is the y intercept of your pair. 
X1 is the x intercept of your coordinate pair, plug them in. If you dont know slope the formula to find it is:
y2-y1/x2-x1

X = 7W? + 4w - 6<br> Y =w2 - 11w +13<br> X-Y<br> Your answer should be a polynomial in standard fom.
svp [43]

Answer: w^2-22w+19

Step-by-step explanation:

X=7w+4w-6\\Y=w^2-11w+13\\

(7w+4w-6)-(w^2-11w+13)\\7w+4w-6-w^2+11w-13\\(7w+4w+11w)+(-6-13)-w^2\\22w-19-w^2\\-w^2+22w-19

Normally we wouldn't have our square variable be negative, so in order to get rid of that negative sign without changing the equation is by multiplying by -1

-1(-w^2+22w-19)\\=w^2-22w+19
