Answer:
I am about 95% sure that this is what they want. P.s (sorry I cant put the divide symbol)
<u><em>The variable is the number of shirts she bought or x</em></u>
and the equation is <u><em>(375+50) divided by (15+2) = x</em></u>
in the solve spot put
<em><u>(375+50) divided by (15+2)=x</u></em>
<em><u>425 divided by 17=x</u></em>
<em><u>x=25</u></em>
Then your answer would be <u><em>25</em></u>
Step-by-step explanation:
first add 50 to 375 so you get the full price which will give you 425. then to find out how many shirts she bought you must add 2 to 15 to get 17. then divide 425 by 17 which is 25. so she bought <em><u>25 shirts</u></em>.
Answer: X means you have to times
Step-by-step explanation: So you will have to do 3x3x3
1. Let's call:
x: the width of the walkway.
b: 2x+16 (there is a widht "x" of the walkway on each side).
h: 2x+32 (there is a widht "x" of the walkway on each side).
A: 924 ft^2 ( the area of the pool of including the walkway).
2. The area of a rectangle is:
A=(b)(h)
b: the base of the rectangle (2x+16)
a: the height of the rectangle (2x+32)
3. Then, we have a quadratic equation:
924=(2x+16)(2x+32)
4x^2+64x+32x+512-924=0
4x^2+96x-412=0
4. We apply the quadratic formula to find the value of "x":
x=(-b±√(b^2-4ac))/2a
x=3.71
The answer is: The width of the walkway is 3.71 ft
Solution= x=5
Alernative form= 21 x - 105= 0<span />
The answer would be 680 because 20% of 850 is 170 so 850-170=680.
