Answer:

10( 3/4x  * 9/500y ) = 10  

Step-by-step explanation:

We know 18% can also be found

when we take the x amount 75 x 0.18 = 13.50

We thereafter find 75-13.50 = 61.50 for Janella's hair cost plus $13.50 tip.

But for x = 750 x 9/500 = 10

We find  13.50 = 10

x= 1.5

18% coincidentally is 13.5 and 13.5 x 1.5 = 18

So we could redesign and use 18 in the equation

A quadratic equation is shown: x2 + 18x + 76 = 0 Which of the following is the first correct step to write the above equation in
tia_tia [17]

Answer:

  x^2 + 18x + 76 + 5 = 0 + 5

Step-by-step explanation:

The first step is to determine the constant that is needed to be able to write the expression in the desired form. That constant is the square of half the x-term coefficient: (18/2)^2 = 9^2 = 81.

The constant that is present is 76, which is 5 fewer than the needed constant, so the "first step" is to add 5 to both sides of the equation:

  x^2 + 18x + 76 + 5 = 0 + 5

Then the next step would be to write the left side as a square:

  (x +9)^2 = 5 . . . . . . . p = -9; q= 5

In a right-angled triangle, the hypotenuse is 113 and a leg is 112.
melomori [17]

Answer: 15

Step-by-step explanation: Use the formula: a^{2}+b^{2}=c^{2}

Remember c^{2} should always be the hypotenuse or the longest side.

112^{2}+b^{2}=113^{2} ---> evaluate the exponents

12544+b^{2}=12769 ----> subtract 12544 to the other side

b^{2}=225 ---> take the square root of both sides

b=15
