Answer:
The number of shirts to be purchased for price to be same is 6 .
Step-by-step explanation:
Given as :
The price for cool shirt = $ 8
The shipping charge for cool shirt = $ 13
The price for Tees = $ 7.50
The shipping charge for Tees = $ 16
Now, Let The number of shirts = S
So , According to question
∵ price to be same for both companies
∴ $ 8 × S + $ 13 = $ 7.50 × S + $ 16
Or, $ 8 × S - $ 7.50 × S = $ 16 - $ 13
Or, 0.5 S = 3
∴ S =
I.e S = 6
Hence The number of shirts to be purchased for price to be same is 6 . Answer

<h3>
B(4, 7)</h3>
Step-by-step explanation:
<h3>
Explanation:</h3>
In the graph x-coordinate represents the number of wind chimes sold and y-coordinate represents the profit Madison earned. If a point is below the x-axis, means it has negative y-coordinate than it represents loss. Points above x-axis should have x-coordinate more than 6 as stated in the question that she started earning profit after selling her first 6 wind chimes. All the points having x-coordinate less than 6 should lie on or below the x-axis.
By the above statement point B is completely wrong. Point C and Point A are also wrong as they both x-coordinate more than 6 but still they are below x-axis.
Point D is the makes most sense here as it has x-coordinate more than 6 and it is above x-axis. This means that when Madison sold 7 wind chimes she was in a profit of $3.75.
Answer:
x = -10
Step-by-step explanation:
3(x+1) +5 = 2x -2
<em>Distribute the 3 to the x+1</em>
3x+3 +5 = 2x -2
<em>Combine like terms</em>
3x + 8 = 2x -2
<em>Subtract 2x from both sides</em>
x + 8 = -2
<em>Subtract 8 from both sides</em>
x = -10
Hope this helps!
Answer:
x = 10
Step-by-step explanation:
It says they equal each other so equal the two separate expressions together
-2x + 30 = 2x - 10
goal is to isolate variable x
add 2x to both sides (this cancels out the -2x on the left side)
30 = 4x - 10
add 10 to both sides (this cancels out the -10 on the right side)
40 = 4x
divide 4 by both sides (cancels out 4 on the right side)
10 = x
