Michelle went shopping for some clothes and found a pair of slacks that cost

Mathematics

rjkz [21]3 years ago
7 0

Answer:

The sirt cost $7.5 before tax.

Step-by-step explanation:

Since the pair of slacks cost twice as much as the shirt, we have:

slacks = 2*shirt

And the total purchase was $22.5, so we have:

slacks + shirt = 22.5

We can create a system of equations such as:

slacks = 2*shirt

slacks + shirt = 22.5

If we apply the first formula on the second we can solve for the value of the shirt, we have:

2*shirt + shirt = 22.5

3*shirt = 22.5

shirt = 22.5/3 = 7.5

So the slacks cost:

slacks = 2*7.5 = 15

Help, i just need the answers and no need for explanations.

Answer:

The equation of the quadratic function shown is;

x^2+ 2x -3

Step-by-step explanation:

Here in this question, we need to know the quadratic equation whose graph was shown.

The key to answering this lies in knowing the roots of the equation.

The roots of the equation are the solution to the quadratic equation and can be seen from the graph at the point where the quadratic equation crosses the x-axis.

The graph crosses the x-axis at two points.

These are at the points x = -3 and x = 1

So what we have are;

x + 3 and x -1

Multiplying both will give us the quadratic equation we are looking for.

(x + 3)(x-1) = x(x -1) + 3(x-1)

= x^2 -x + 3x -3 = x^2 + 2x -3

Gina sells 216 cakes in ratio small : medium: large=5:7:12 The profit for one medium cake is twice the profit for one small cake
Hunter-Best [27]

Answer:

£1.31

Step-by-step explanation:

5+7+12=24

216÷24=9

Small=9x5=45

Medium=9x7=63

Large=9x12=108

2x= Medium, Large= 3x, Small=x

Small=45x, Medium= 63x2=126x, Large=108x3=324x

45x+126x+324x=495x

£648.45=495x

£648.45÷495=x

£1.31=x
