We can answer the problem using a rule of three, simple, direct proportion and also using fractions. First the rule of three:
8 apples ------> 15 min
16 apples ----> x
x = (16)(15)/8
x = 30
therefore he can eat 16 apples in 39 minutes.
We can also equate fractions like so:
8/15 = 16/y
and solve for y:
y = 15*16/8
y = 30
the same answer
I think it is D) because the 2x is really the x-axis. But im not sure... A and B are crossed out bc there negatives. Sooo.. its C or D.
H=Hours he an skate; T=total cost
T=$7.00+($1.50/hr)H
T-$7.00=($1.50/hr)H
(T-$7.00)/($1.50/hr)=H
For T=$19:
($19.00-$7.00)/($1.50/hr)=H
$12.00/($1.50/hr)=H
8hrs=H
ANSWER: Jon can skate 8 hours for $19.00.
Hope this helps!
Answer: The answer would be letter A
slope (m)=-9/2
intercept on x-axis=56/9
intercept on y-axis=28
Explanation:
18x+4y=112
(18x)/112+(4y)/112=1
(x/1)/(56/9)+y/28=1
intercept on x-axis=56/9
intercept on y-axis=28
now, 4y=-18x+112
y=-9/2x+28
so, slope (m)=-9/2
Step-by-step explanation:
Move all terms that don't contain y to the right side and solve.
y
= 28 − (9
x)
/(2)
Answer:
self realization, confidence
Step-by-step explanation:
also these concepts are used in real life jobs but most people think otherwise because you dont use them in a grocery store... yeah people think that, but also its so these concepts that were figured out thousands of years ago dont fade away with the newer generations
