The total cost of her haircut was 28 dollars
step by step:
(percentage) 15 x 6 = 90
4.20 x 6 =25.2
(perscentage) 15 divided by 3 = 5
4.20 divided by 3 = 1.4
1.4 + 1.4 = 2.8
25.2 + 2.8 =28
Answer:
x=6,-4
Step-by-step explanation:
Ok so we know the 2 angles are congruent so you need to set them equal to each other. x^2+5x=7x+24. Then get the x's together so you subtract by 7x to get x^2-2x=24. You would then get 24 on the other side so subtract by 24 to get x^2-2x-24. You then would need to factor the equation out. The factored form would be (x-6)(x+4). Then set it equal to 0 to get 6 and -4.
Answer:
9
Step-by-step explanation:
24 divided by 2
12-3
9
Well we know that
15/60 can be reduced to 1/4
And 1/4 can be turned into a percent as 25%
So your answer is 25%
Good Luck! :)
