harina [27]

Answer:

Haircuts cost $50.33

Hair Color costs $80.33

Step-by-step explanation:

Let haircut be cost "a"

coloring be cost "b"

2 haircut, 4 coloring equals 422, we can write:

2a + 4b = 422 {Equation 1}

5 haircut, 4 coloring, equals 573, we can write:

5a + 4b = 573 {Equation 2}

We now multiply equation 1 with -1 and add it with Equation 2 to get:

-1(2a + 4b = 422) = -2a - 4b = -422

Now,

-2a - 4b = -422

5a + 4b = 573

----------------------

3a = 151

a = 151/3 = $50.33

Now, to find b, we plug in this value into any equation and solve for b:

2a + 4b = 422

2(50.33) + 4b = 422

4b = 422 - 100.66

b = $80.33

Haircuts cost $50.33

Hair Color costs $80.33

Is the value of the fraction 7−2y/6 greater than the value of the fraction 3y−7/12 ?
Sveta_85 [38]

Complete Question:

Is the value of the fraction 7−2y/6 greater than the value of the fraction 3y−7/12 ?  For what values?(Make sure to use an inequality)

Answer:

y < 3

Step-by-step explanation:

The given two fractions are:

\frac{7-2y}{6} and \frac{3y-7}{12}

We have to tell for which range of values is the value of first fraction larger than the second fraction. This can be done by setting up an inequality as shown:

\frac{7-2y}{6} >\frac{3y-7}{12}

The range of y which will satisfy this inequality will result in first fraction of larger value as compared to the second fraction.

Multiplying both sides of inequality by 12, we get:

12 \times \frac{7-2y}{6} > 12 \times \frac{3y-7}{12} \\\\  2(7-2y)>3y-7\\\\ 14-4y>3y-7\\\\ 14+7>3y+4y\\\\ 21>7y\\\\ 3>y\\\\ y

This means, for y lesser than 3, the value of first fraction is larger than the second one.
