ex15.95+.73x=173.63
.73x=173.63-15.95
.73x=157.68
x=157.68/.73
x=216 miles driven.
PROOF;
15.95+.73*216=173.63
15.95+157.68=173.63
173.63=173.63
Answer: Keith drove the truck for 123 miles
Step-by-step explanation:
17.99+0.97m=137.30
Subtract 17.99 on both sides:
17.99-17.99+0.97m=137.30-17.99
0.97m=119.31
Divide 0.97 on both sides:
0.97m/0.97=119.31/0.97
m=123 miles

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.
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

Greg currently has 30 and receives a new one every 4 months. As a competition, Mark wants to start collecting ties as well. He buys a tie every month until he has the same amount as Greg. How many months until Mark has the same amount? How many ties are there? Hint: use one variable for “# of months” and one for “# of ties”.
9514 1404 393
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.

A farmer has a crop of 2,000 orange trees at the beginning of this year. Each year,
the farmer plans to plant 250 new trees. Assuming all of the trees from one year
live into the next, which explicit formula below can be used to determine the total
number of orange trees, a.,, on this farm at the end of the nth year?
a, = 2,250+250(n-1)
a, = 2,000 + 250(n-1)
a, = 2,250+250(n + 1)
a, = 2,000 + 250(n + 1)

How do you solve linear equations with substitutions?
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
2. The angle measures of a triangle are shown in the diagram.
What is the value of X
Answer: The angles inside a triangle are called interior angles. ... The three interior angles in a triangle will always add up to 180°. At each corner the exterior and interior angles are on a straight line, so at each corner these two angles add up to 180°.
Step-by-step explanation:
Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral.

Are the ratios 4:6 and 6:9 equivalent?
Answer: No
Step-by-step explanation:
Yes, the two ratios 4:6 and 6:9 are equal to 2:3.
What is a ratio?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.
Given that there are two ratios 4:6 and 6:9. The equivalence of the two ratios will be calculated as:-
4 : 6 = ( 2 x 2 ) ÷ ( 2 x 3 )
4 : 6 = 2 : 3
6:9 = ( 2 x 3 ) ÷ ( 3 x 3 )
6: 9 = 2 : 3
4 : 6 = 6:9 = 2:3
Therefore, the two ratios 4:6 and 6:9 are equal to 2:3.

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.
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
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.
