Answer:

5 shirts

Step-by-step explanation:

Step one:

given data

Each shirt costs $15.00 including tax.

A one-time shipping fee of $3.25

The total cost of Jill's order is $78.25

Step two:

let the number of shirts be x

so

y=15x+3.25

for y= $78.25, let us find x

78.25=15x+3..25

collect like terms

75= 15x

divide both sides by 15

x=75/15

x=5

sorry sir i dont really know

Answer:10

Step-by-s First of all, note that 15 is the same as 15/1 since 15 divided by 1 is 15. Therefore, start by setting up the problem like this

Step 2: Multiply

Multiply the numerators together (15 x 2 = 30) and multiply the denominators together (1 x 3 = 3) and make it into one fraction like so:

Step 3: Minimize

The greatest common factor of 30 and 3 is 3. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:

Step 4: Convert

Convert the improper fraction above to a whole number to get the answer:

That's it! Now you know how to calculate 15 times 2/3.

Answer:

y + 2 = (x - 2)

Step-by-step explanation:

From the graph, you can see that when y = 0, x = 2, and vise versa. Taking this into consideration, if y = 4, x = 2, so, the answer is y + 2 = (x - 2)

Answer:

C

Step-by-step explanation:

Given the 2 equations

5x + 2y = 29 → (1)

x + 4y = 13 → (2)

Multiplying (1) by - 2 and adding to (2) will eliminate the y- term

- 10x - 4y = - 58 → (3)

Add (2) and (3) term by term to eliminate y

- 9x + 0 = - 45

- 9x = - 45 ( divide both sides by - 9 )

x = 5

Substitute x = 5 into either of the 2 equations and solve for y

Substituting into (2)

5 + 4y = 13 ( subtract 5 from both sides )

4y = 8 ( divide both sides by 4 )

y = 2

Solution is x = 5, y = 2 → C

Answer:

c) x = 5, y = 2

Answer:

  A.  3/13

Step-by-step explanation:

The slope formula is ...

  m = (y2 -y1)/(x2 -x1)

Using the given points, this is ...

  m = (-4 -(-1))/(-8 -5) = -3/-13 = 3/13

Answer:

length of each edge = (x + 3)

Step-by-step explanation:

The surface area of each face of the cube = ([tex]x^{2}[/tex] + 6x + 9) [tex]m^{2}[/tex]. But the surface of a cube has the shape of a square. So that,

Area of a square = length x length

                            = [tex]l^{2}[/tex]

By factorizing the area,

[tex]x^{2}[/tex] + 6x + 9 = [tex]x^{2}[/tex] + 3x + 3x + 9

                  = ([tex]x^{2}[/tex] + 3x) (3x + 9)

                  = x(x +3) + 3(x + 3)

                  = (x + 3)(x + 3)

                  = [tex](x + 3)^{2}[/tex]

[tex]x^{2}[/tex] + 6x + 9 = [tex](x + 3)^{2}[/tex]

Thus,

[tex](x + 3)^{2}[/tex] = [tex]l^{2}[/tex]

find the square root of both sides

l = (x + 3)

length of each edge = (x + 3)

Answer:

Y=−3x2+6x+9

Step-by-step explanation:

Answer:

(3x-5) + 2x = 90

Step-by-step explanation:

We know that there are 180 degrees in a triangle. We also know that one angle is 90 degrees.

This means that (3x-5) + 2x = 90.

Answer:

D -2/5

Step-by-step explanation:

So first you count up or down from a point, that's 2

then you'll count side to side that's 5

2/5

but this is a negative slope because it's pointing up to the left

-2/5 is the slope

Answer:

-2 tiles

Step-by-step explanation:

In each figure, 5 tiles are added.

Subtract 5 from how many tiles are in Figure 2 (8 tiles) & you get 3.

3 is how many tiles are in Figure 1, meaning you need to subtract 5 again to see how many are in Figure 0! 3-5 = -2.

Answer:

Rhion did better in maths test.

Step-by-step explanation:

Given that:

Rhion scored 14 out of 17.

We will find percentage and then compare them.

Percentage = [tex]\frac{Score}{Total\ marks}*100[/tex]

Percentage = [tex]\frac{14}{17}*100[/tex]

Percentage = 82.35%

Rhion scored 31 out of 39.

Percentage = [tex]\frac{31}{39}*100[/tex]

Percentage = 79.48

On comparing,

82.35 > 79.48

Hence,

Rhion did better in maths test.
