Step-by-step explanation:
The point-slope form of a line is given by

where
is the point on the line. So we can write the equation as

We can add the fractions together to compare with how much sugar she needs.

So Juvi has
cups of sugar.
She needs
cups, so let's make the denominators the same and compare.


Since
>
, she has enough sugar to make 4 batches of brownies.
Hope this helps.
頑張って!
Answer:
Sue = 25.75
Dave = 29.5
Tom = 19.75
Sue = s
Tom = t
Dave = d
Step-by-step explanation:
s+t+d = 75
s-6=t
d +16 = s+t
d+16+d= 75
2d = 59
d = 29.5
t = s-6
t+s = 45.5
s-6+s= 45.5
2s = 51.5
s= 25.75
t= 19.75
Answer:
- 150 short-sleeved shirts
- 100 long-sleeved shirts
Step-by-step explanation:
Let S and L represent the numbers of short- and long-sleeved shirts ordered.
The expected earnings were ...
5S +10L = 1750
The number sold was ...
(1/3)S + (1/2)L = 100
We can multiply the first equation by 1/5 and the second equation by 6 to put the equations into standard form:
Subtracting the second equation from twice the first gives ...
2(S +2L) -(2S +3L) = 2(350) -(600)
L = 100 . . . . . . simplify
2S +3(100) = 600
S = 150
150 short-sleeved and 100 long-sleeved shirts were ordered.
It is more appropriate to round to the nearest tenth inch because inches are normally whole numbers and when you are rounding off inches, you want to make sure that your answer is as simplified as possible so it is easier to calculate in the long run.
