Jimmy wants a burger. It is $30 but he has a coupon for 10% off. How much does he spend?
The graph of a proportional relationship is shown. What is the
amount of savings per
week?
Money
470
376
A) $94/week
B) $47/week
C) $18.80/week
D) $23.50/week
Answer: B) $47/week
===========================================================
Explanation:
Because the graph goes through the origin, we can simply divide the y value over the x value. Do so for any point on the diagonal line.
For example, picking (x,y) = (2, 94) leads to k = y/x = 94/2 = 47 being the constant of proportionality and also the amount of savings per week.
You can think of it like this:
2 weeks = $94 in savings
2/2 weeks = $94/2 in savings ... divide both sides by 2
1 week = $47 in savings
leading to the savings rate of $47 per week
----------
Side note: This linear equation is y = 47x. It is in the form y = kx with k = 47. It is a direct proportion equation. The constant of proportionality is also the slope. All direct proportion equations are linear and go through the origin.

Step-by-step explanation:
The first thing you do here is convert 9 quarts to gallons. To convert from quarts to gallons you dvide by 4. So 9/4=2.25.
The next thing you do is divide this number by two to achieve your answer
2.25/2=1.125
So the final answer you would be after using half of his paint Gary is left with 1.125 gallons of paint

Answer:
x = 2/3
Step-by-step explanation:
cross multiply
-9(x-4) = 10(3x+1)
and then solve the equation
-9x + 36 = 30x + 10
36 = 39x + 10
26 = 39x
x = 2/3

Blake sold 17 verses for $3.25 each he spent $16.21 on materials to make the vases what is the profit
Answer:
We can calculate what did he get, as we know he sold 17 vasess for 3.25 dollars each of them, we can multiply:
17 * 3.25 = $55.25
Now, we know he got 55.25 dollars but he spent 16.21, so we substract:
55.25 - 16.21 = $39.04
His profit selling that is of 39.04 dollars..

Answer:
A= 60
Step-by-step explanation:
1/2*12*10
60
7 + 13а – 3- 20 + 2а
7 + 13а – 3- 20 + 2а
combine like terms
7+13a+2a-3-20
7+15a-3-20
then do -3-20
-3-20=-23
7+15a-23
7-23=-16
15a-16
answer:
15a-16 or -16+15a
can someone please help with this?!

Answer:
A
Step-by-step explanation:
A car covers a distance of 600 m in 2 minutes whereas a train covers a distance of 75 km in 50 minutes. Find the ratio of their speed.
answer
1:5
Step-by-step explanation:
To find speed use the formula
speed=distance/time
The car's speed is 600m ÷2mins(120secs)
(600÷120)
5m/s
The trains speed will be
speed=distance/time
=75÷50mins(5/6hrs)
=90km/hr
Ratio of their speed should be
first change the speed of the car 5 m/s to km/hr. 5×18/5 = 18km/hr
the speed of the train is 90km/hr
18:90 simplified it will be 1:5
What is the solution to the system graphed below?
Answer:
