Answer:
Pauli's pizzeria make more money per pizza
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find out the slope of the graph of Leo's pizzeria
looking at the graph take the point (2,24)
The graph show a proportional relationship (the line passes through the origin)
The slope is m=y/x
we have
For x=2, y=24
substitute
m=24/2=$12 per pizza sold
The linear equation is
y=12x
step 2
Compare the slopes
<em>Pauli's pizzeria</em>
we have
y=15x -----> slope m=$15 per pizza sold
<em>Leo's pizzeria</em>
we have
y=12x -----> slope m=$12 per pizza sold
$15 per pizza sold > $12 per pizza sold
therefore
Pauli's pizzeria make more money per pizza
Answer:
B
Step-by-step explanation:
To find the constant of proportionality between y and x, divide 
for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
Using the method above, you should get:
Chart A = 2/5
Chart B = 1/5 (Correct Answer!)
Chart C = N/A
Hope this helps!
Answer:
35 [$]
Step-by-step explanation:
1) if Peter's sum is p and Jacky's is j, then the ratio 5:2 in the condition can be written j/p=5/2;
2) the phrase 'after Jacky gave 15 dolls to Peter, they have an equal number of dolls' can be written as j-15=p;
3) using the two above it is possible to make up the system of two equations:
4) finally, the have together 10+25=35 doll-s.
Correct answer:
X = 5
Y = -2
Answer:
Step-by-step explanation:
So first let us break how much trinkets one worker can make and find out the time frame. So the first two workers each can make a trinket in 90 seconds, 90/2 is 45 (seconds) for 1 worker. And the third worker takes 10 seconds longer, so 45+10 is 55 seconds for the third worker to make 1 trinket. There are 60 minutes in a hour, 60x60(seconds) is 3600 seconds in an hour. But here we will have to do 3600/100, because we forget about the individual time and focus on the combined time. So we add 10 more to 90, and now get 3600/100, which gives us out result of 36 trinkets made in an hour
sorry it took long i burnt my brain for this one
