To rent a moving truck for the day it cost $33 +1 dollar for each mile driven.
Answers
Answer:
A) y=x+33 or 33+m (m = miles)
B)$333
Step-by-step explanation:
A is, y = the total cost, x = miles driven , 33 = cost for the day you rent it
B is, $1x$300 = $300 + $33 (base cost) = $333
Write an expression for the cost to rent the truck.
33 + x = y
You rive the truck 300 miles. How much do you pay?
33: initial rent fee
300: miles
One mile equals one dollar so the answer would be.
33 + 300 = 333
Hope this helped!
Find the next two terms. 2, 10, 50, ?, ?
Answers
Hi there!
The next 2 terms are 250 and 1,250.
We have a geometric sequence, which means we use multiplication or division to get to the next term.
Here, we multiply by 5 to get to the next term.
So we multiply 50 by 5:
50*5=250
We multiply 250 by 5 to get to the next term:
250*5=1,250
And we're done!
Therefore, the next two terms are: 250 and 1,250.Hope this helps!

Answer:
250, 1250
Step-by-step explanation:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 5 gives the next term.

Working together, Edward and Frances can wallpaper an apartment in 12 hours. It would take Frances 30 hours to do the same job by herself. How long would it take Edward to do it alone?
Answers
Answer:
Step-by-step explanation:
Givens
together: 12 hours
Frances: 30 hours
Edward: x
Formula
The formula is an odd one that shows up in physics as well.
1/Frances + 1 / Edward = 1/Together.
Solution
1/30 + 1/x = 1/12
LCD for 12 and 30
12: 2 * 2 * 3
30:3 * 2 * 5
LCD: 2*2*3*5
LCD: 60
2/60 + 1/x = 5/60 Subtract 2 / 60 from both sides
1/x = 5/60 - 2/60
1/x = 3/60 Cross Multiply
3x = 60*1 Divide by 3
3x/3 = 60/3
x = 20
So Edward (doing it alone) takes 20 hours to do the job.

1.) I'm trying to see if I got this answer right. If not, correct me.
Answers
Step-by-step explanation:
The constant of proportionality (or constant of variation), denoted by "k," represents the constant proportion or ratio that exists between two variables, y and x, such that y = kx.
The given problem asks for you to identify the constant of proportionality and what it represents in context of the problem.
In the equation, y = 4.75x:
y = total cost in dollars earned
x = number of bracelets
The constant of proportionality, k = 4.75, represents the increase in total cost earned for every x number of bracelets sold. In other words, the total increases by 4.75 for every bracelet sold.
Thus, since Liv made x = 2 bracelets, then her total cost will equal to $9.50 because:
y = 4.75x
y = 4.75(2)
y = 9.50

..A teacher is buying T-shirts for her algebra class.
- Long-sleeve T-shirts (x) cost $16 each.
- Short-sleeve T-shirts (y) cost $10 each.
The teacher wants to buy at least 24 T-shirts, and she wants to spend no more than $300 in all. Which system of inequalities represents this situation?
Answers
Answer:
[tex]240\leq 10x+16y\leq 300[/tex]
Step-by-step explanation:
Let short-sleeve be x and long-sleeve be y
So, the least amount she could spend buying at least 24 shirts is $240 because the cheapest shirt is $10/shirt. The max amount is already given.
