Answer:
Step-by-step explanation:
8x + 34 = 130 <u>(Vertical Angles are Equal)</u>
Subtract 34 to both sides
8x = 130 - 34
8x = 96
Divide both sides by 8
x = 96 / 8
x = 12

Answer:
Division can be represented with ÷ as well.
So do
25x16=400
this shows how many raffle tickets were sold all together
Then do 400x$15 =$6000
So all together they raised $6000
Answer:
Step-by-step explanation:
9 * 44 =
9 (40 + 4) =
9(40) + 9(4) =
360 + 36 = 396
Your equation: 4x² - 100 = 0
Factor the left side: (2x + 10) · (2x - 10) = 0
This equation is true if either factor is zero.
-- One factor: 2x + 10 = 0
Divide each side by 2: x + 5 = 0
Subtract 5 from each side: x = -5 .
-- The other factor: 2x - 10 = 0
Divide each side by 2: x + 5 = 0
Add 5 to each side: x = 5 .
