<h2><u>
PROPORTIONAL EQUATION</u></h2><h3>Exercise</h3>
Apply the means-extremes property of proportions: this allows you to cross multiply:


Apply the distributive property:



Add 24 to both sides:


Substract 3x to both sides



<h3><u>Answer</u>. The value of x = 24.</h3>
Answer:
I would assume $10 is the cost of the booth and 5 is how much she earns for each T-Shirt, so the equation would be 5x-10=65. Assume $65 is what she earned.
Therefore, the equation may be: (your question did not specify) 5x-10=65. so x is 15. Therefore, she sold 15 T-Shirts.
Correct Form:
_-_
_
7(x - 2) - 3(3 + X) greater than 1
7 X - 14 - 9 - 3 x greater than 1
4 x -23 greater than 1
4 x greater than 1 + 23
x is greater than 6
Answer:
f = -5, s = -6
Step-by-step explanation:
F= first number
S= second number
4f - s = -14
f + 3s = -23
3(4f - s = -14)
12f - 3s = -42
+ f + 3s = -23
13f = -65
————
13
f = -5
4f - s = -14
4(-5) - s = -14
-20 - s = -14
+20 +20
-s = 6
———
-1
s = -6
Move all terms that dont contain y to the right side and solve and you get:
y=4x/3-7
Hope this helps
