Answer:
Ok so we can see for every 2 cups of medium coffee, the balance goes down 5.30$. So that means that for every coffee, her balance goes down 2.65$. Solving for the x-intercept means how many medium coffees can I get until my balance is 0. First, we have to find the y-int so it's easy. The slope is -2.65 because for every medium coffee, her balance goes down 2.65$. So we have y=-2.65x+b. Plugging in any point, I choose (4,14.40), we get 14.4 = -2.65 × 4 +b. Solving for b we get 25 for the y intercept, meaning the equation is y = -2.65x + 25 . To find the x intercept, we set y=0. So we have 0 = -2.65x+25. Solving for x we get approx. 9.4. We can't have decimals so we round down to 9. So the x int is ≈ 9.4 meaning we can only buy 9 coffee and have a little extra. But, if the problem said how many more coffees can she get, then here is how we do it. Since she already got 4 coffees, and the max is 9, we do 9-4 and we get 5, so she can buy 5 coffeed more.

Answer:
m = 2
Step-by-step explanation:
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
( - 4 , - 3 )
( - 5 , - 5 )
m = [tex]\frac{-5+3}{-5+4}[/tex] = 2

There are 9 people going on a trip. They purchased coach tickets for $160, and first class tickets for $1180. The total budget to spend was $4500. How many first class tickets did they buy? How many Coach tickets did they buy? Show your work.
Answer:
Step-by-step explanation:
Given
There are 9 people going on a trip
They purchased coach tickets =$160
first class tickets =$1180
total budget to spend = $4500
Let coach tickets=X
So first class tickets=9-x
160x+1180(9-x)=4500
160+10620-1180x=4500
160x-1180x=4500-10620
-1020x=-6120
X=6120/1020
X=6
So answer
Coach tickets=X=6
First class tickets=(9-x)
=3.
solve for r: q = p(r + s)
Answer:
[tex]r=\frac{q-ps}{p}[/tex]
General Formulas and Concepts:
Order of Operations: BPEMDASEquality PropertiesDistributive PropertyStep-by-step explanation:
Step 1: Define equation
[tex]q=p(r+s)[/tex]
Step 2: Solve for r
Distribute p: [tex]q=pr+ps[/tex]Subtract ps on both sides: [tex]q-ps=pr[/tex]Divide both sides by p: [tex]\frac{q-ps}{p} =r[/tex]Rewrite: [tex]r=\frac{q-ps}{p}[/tex]Step-by-step explanation: To solve for r, start by distributing the p
through the parentheses on the left side to get q = pr + ps.
Next, isolate the r term by subtracting ps from both sides to get -ps + q = pr.
Finally, to get r by itself, divide both sides by p and we have -ps + q/p = r.
1. Erik buys carrots and dip for a class snack. The carrots are $3.80, and the dip is $2.60. Erik has a coupon for 5% off his groceries. He does not need to pay tax. He gives the cashier $20. How much change does he receive back?
2. Liam buys a new TV that cost $360. The TV is on sale for 40% off, and the store is offering an additional 20% off all sale items. How much does Liam save on the TV?
Answer:
1. $3.80 + 2.60=$6.40 *.05=$5.08
$20.00-$5.08=$14.92
2. $360 x %40=$14,000
$14,000/100=144 360-144 = 216
$216 x %20 = $4,320/$100= $43.20
$216-43.20= $172.8
$360-$172.80=$187.20

Answer: 120
120
Step-by-step explanation:
I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)
P/w = part/whole = ?/400
%/100= percent/100 = 30%/100
These numbers are equivalent
If you don’t understand the top then here is how to do the work-
400x30=12000
12000/100=120
Therefore it’s 120

Answer:
x + 2x = 108
Step-by-step explanation:
Let x be the number of oranges sold on Thursday
The number of oranges sold on Friday is twice as many or 2 times x, 2x
The total sold on the two days is 108. Add the number sold on Thursday and Friday together and let it equal to 108
x + 2x = 108
Mrs. Kelly bought a bag of flour that holds 1623 cups of flour. Each loaf of banana bread uses 23 cup of flour.
How many loaves of banana bread can she make?
Answer:
69 loaves
Step-by-step explanation: (Sorry if you don't understand I am not that good at explaining)
First you need to divide 1,623 by 23 because each loaf is 23 cups of flour.
So 1,623 divided by 23 equals 70.56 but you can't have a fractioned number so it needs to be a whole loaf of bread so she can make 69 loaves of bread

How many ways are there to put 4 balls in 3 boxes if the balls are not distinguishable but the boxes are?
Answer:
15 outcomes
Step-by-step explanation:
the balls are all the same so the only differenciating thing is how many balls are in each individual box.
The boxes can have
0,0,4 3 possibilities
0,1,3 6 possibilities
0,2,2 3 possibilities
1,1,2 3 possibilities
So that are 15 unique outcomes
Solve 7(y + 2) – (4y – 10) = 44 – 2y + 5
A.y = -5
B.y = 5
C.y = -10
Answer:
y = 5
Step-by-step explanation:
7(y + 2) – (4y – 10) = 44 – 2y + 5
(7y+14) - (4y - 10) = 49 -2y
3y +24 = 49 -2y
5y +24 = 49
5y = 25
y = 5
Answer:
y=5
Step-by-step explanation:
7(y+2)-(4y-10) = 44-2y+5 distribute on the left and combine like terms on the right side of the equation
7y + 14 -4y +10 = 49 - 2y move every term with a variable on the left side with a change sign and the numbers on the right side
7y-4y+2y =49 -14 -10
5y = 25 divide both sides by 5
y5/5=25/5 so
y=5

Each pair of points lies on a line with the given slope. Find y.
Answer:
3/4
Step-by-step explanation:
If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in
1/4(x)=y
1/4(3)=y
3/4=y
And the other one is incorrect
1/4(x)=y
1/4(7)=y
1 3/4 =y
