They sold 76 t-shirts and 24 warm up pants.
Step-by-step explanation:
Cost of one t-shirt = $20
Cost of warm up pants = $45
Total sold = 100
Worth of sold items = $2600
Let,
x be the number of t-shirts.
y be the number of warm up pants.
According to statement;
x+y=100 Eqn 1
20x+45y=2600 Eqn 2
Multiplying Eqn 1 by 20

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 25

Putting y=24 in Eqn 1

They sold 76 t-shirts and 24 warm up pants.

The slope of a line is given by the ratio of the rise to the run of the line.
The value of, y is <u>4</u>
Reasons:
The given points on the line are; (-4, y), and (5, 7)
The slope of the line, = 
Required:
To find the value of <em>y</em>
<em />
Solution:
The formula for the slope is given as follows;

Where;
(x₁, y₁) = (-4, y)
(x₂, y₂) = (5, 7)
Which gives;

3·(7 - y) = 1·(5 + 4) = 9
21 - 3·y = 9
3·y = 21 - 9 = 12

The value of, y = <u>4</u>

Answer:
she was left with 28$ I'm in high school i think I'm right
Step-by-step explanation:
Answer:
600
Step-by-step explanation:
So lets rememer the formula for volume of a pyramid to sovle this:
LxHxW/3
Now lets plug in our values, for L, H, and W.
15x12x10/3
So, 15x12x10 is 1800. That is the height times the length times the width.
Now, since this isnt volume of a cube, we must divide the total my 3. This is how you find the volume of a pyramid, as I said above.
So it should be:
1800/3
=
<u>600</u>
This is your answer.
I hope this helps : )
Good luck!
Z would equal 2 hope this helps!!
