The answer would be B) 6, 4
mark me brianliest if i was correct!
1. 5x= -80. x= -16
2. x - 73 = 129. x = 202
3. x/-8 = 22. x = -176
4. 2x + 8 = 8. 2x = 0. x = 0
5. 3x - 7 = 40. 3x = 47. x = 47/3
Answer: 16 red velvet cupcakes.
Step-by-step explanation:
To solve this problem you can apply the following proccedure:
- Let's call the number of red velvet cupcakes in a box that has 24 chocolate cupcakes: 
- Based on the information given in the problem, you can set up the following proportion and Solve for
<em>:</em>

There are 16 red velvet cupcakes in a box that has 24 chocolate cupcakes.
Answer:
x = 24
Step-by-step explanation:
Since this is a right angle, we can use the Pythagorean Theorem to find x. In the formula, a^2 + b^2 = c^2, variables a and b represent the lengths of the legs, and variable c represents the length of the hypotenuse.
a^2 + b^2 = c^2
18^2 + x^2 = 30^2
324 + x^2 = 900
x^2 = 576
x = 24
Zero × anything is zero, so no... you'll never see 0x. If for some reason you do, just rewrite the equation without it... because it's zero. :)
