Answer:
40 months
Step-by-step explanation:
Let t represent the number of months. Then Greg's tie count (g) will be ...
g = 30 + t/4 . . . . . . average rate of tie accumulation is 1/4 tie per month
And Mark's time count (m) will be ...
m = t . . . . . . . . . . . . average rate of tie accumulation is 1 per month
We want these numbers (g, m) to be equal:
g = m
30 +t/4 = t . . . . . substitute the equivalent expressions
30 = 3/4t . . . . . . subtract t/4
40 = t . . . . . . . . . multiply by 4/3
After 40 months, Mark and Greg will have the same amount of ties.

Zoe owns a food truck that sells tacos and burritos. She only has enough supplies to
make 113 tacos or burritos. She sells each taco for $3 and each burrito for $6. Zoe
must sell at least $510 worth of tacos and burritos each day. If 53 tacos were sold,
determine all possible values for the number of burritos that Zoe must sell in order to
meet the requirements. Your answer should be a comma separated list of values. If
there are no possible solutions, submit an empty answer.
Answers
Answer:
58.5
Step-by-step explanation:
If you take 53 times 3 = 159
take 510 - 159 = 351
then take 351 divided by 6 = you get 58.5

How do you solve linear equations with substitutions?
Answers
Answer:
The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Step-by-step explanation:
Solve the following system by substitution.
2x – 3y = –2
4x + y = 24
The idea here is to solve one of the equations for one of the variables, and plug this into the other equation. It does not matter which equation or which variable you pick. There is no right or wrong choice; the answer will be the same, regardless. But — some choices may be better than others.
For instance, in this case, can you see that it would probably be simplest to solve the second equation for "y =", since there is already a y floating around loose in the middle there? I could solve the first equation for either variable, but I'd get fractions, and solving the second equation for x would also give me fractions. It wouldn't be "wrong" to make a different choice, but it would probably be more difficult. Being lazy, I'll solve the second equation for y:
4x + y = 24
y = –4x + 24
Now I'll plug this in ("substitute it") for "y" in the first equation, and solve for x:
2x – 3(–4x + 24) = –2
2x + 12x – 72 = –2
14x = 70
x = 5

How many diagonals can be constructed from one vertex of an n-gon? State your answer in terms of n and, of course, justify your answer.
Answers
Polygon Diagonals. The number of diagonals in a polygon = n(n-3)/2, where n is the number of polygon sides. For a convex n-sided polygon, there are n vertices, and from each vertex you can draw n-3 diagonals, so the total number of diagonals that can be drawn is n(n-3).

you plan to open a lemonade stand near where you live. The cost to buy the wood is $60 and the cost to make the lemonade is $3 per cup. You plan to sell each cup pf lemonade for $5. Let x be the number of cups of lemonade sold. Write a function P(x) that represents the total profit you earned from selling x cups of lemonade
Answers
Answer:
P(x)=2x-60
Step-by-step explanation:
From the information provided, the function P(x) would indicate that the total profit you earned from selling x cups of lemonade is equal to the result of multiplying the price per cup for the number of cups minus the total cost. This cost is the result of adding up the cost of buying wood plus the cost per cup for the number of cups:
P(x)=5x-(60+3x)
P(x)=5x-60-3x
P(x)=2x-60
According to this, the function is: P(x)=2x-60.
