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

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:

a.  He used an incorrect time ratio converting hours to minutes.

d. He incorrectly concluded that she is not running fast enough.

Step-by-step explanation:

Looking at the Coach's method of conversion when converting time, he assumed that an hour had 15 minutes instead of 60 minutes. He therefore did not use the correct time ratio to convert hours to minutes.

The coach's calculations yielded an answer of 34 ft/s. This is way faster than 8.8 ft/ s so his deduction that she was not running fast enough to beat her fastest time is incorrect because at that inhumane speed, she did.

Answer: A.)He used an incorrect time ratio converting hours to minutes.

D.)He incorrectly concluded that she is not running fast enough.

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:

9d+3

Step-by-step explanation:

(6d+5)-(2-3d)

First, I like to put a 1 in front of the second grouping of numbers to help me with the distributing:

(6d+5)-1(2-3d)

Distribute the -1:

(6d+5)-2+3d

Remove parenthesis and combine like-terms:

9d+3

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:

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 + 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:

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.

[tex]\tt{ 6(4c-2) }[/tex]

[tex]\tt{ 24c-12 }[/tex]

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:

x = 41
