Answer:
your mom
Step-by-step explanation:
-1/2x < -12
(divide both side by -1/2, or -0.5 )
x > 24
A)
160c / 20m
1c / (20/160)m
therefore, he takes 1/8 minutes to burn 1 calorie
b)
m = rise/run = 20/160 = 1/8
The complete question in the attached figure
we know that
the ratio is 1:3
that means
(1+3)=4 liters
To prepare 4 liters of fruit punch use 1 liter of orange juice and 3 liters of <span>pineapple
so
</span><span>to Make 3 Liters of fruit punch
</span><span>the proportion to find the pineapple liters will be
3/4=x/3------> x=9/4-----> 2.25 liters of </span><span>pineapple
</span>
the answer is2.25 lt pineapple
That's a pretty confusing one. I think it's 10 minutes.
