Answer:
8 = y
Step-by-step explanation:
In order to find a solution to an algebraic equation such as this one we simply need to isolate the variable. We do this by applying the opposite operation to each side in order to get rid of the other factors and get the variable alone. Like so...
20 = y + 12 ... we need to subtract 12 from both sides to get rid of the 12 on the right side with the variable y.
20 - 12 = y + 12 - 12
8 = y
Finally, we can see that the value of the variable y is 8
Too hard for me. I'm only in 5th grade
She would make 3.00 dollars
50(10) - 20(10) = (10)(50 - 20)
500 - 200 = (10 * 30)
300 = 300
(10)(50 - 20) = 30(10)
(10 * 30) = 300
300 = 300

Now to solve this square equation we need to find Descriminant

As Descriminant D is greater than 0 then we have 2 solutions which we can calculate by this formula

Answer:
x=12
Step-by-step explanation:
Since AB=BD, they have equal length. 15x+4=2x+160, 13x=156, x=12
