we know that
1) Mailyn can eat 32 cookies in an hour
1 hour is equal to 60 minutes
<u>Find how cookies eats Mailyn in one minute</u>
by proportion

2) Juan needs 3 hours to eat 32 cookies
<u>Find how cookies eats Juan in one minute</u>
by proportion

<u>3) Find how long will it take them to eat 40 cookies together</u>
we know that
Maylin and Juan eats in one minute together ---------> (0.53+0.18)=0.71 cookies
so
by proportion

therefore
<u>the answer is</u>

Answer:
4/9 and 5/18
Step-by-step explanation:
Total: 5+8+5=18
the probability of selecting a Republican is 8/18=4/9
the probability of selecting a Democrat is 5/18
Answer:
3/4 = 9/12 2/3 = 8/12
Step-by-step explanation:
To find the common denominator you multiply by the opposite ones
3 • 3 9
__ = __
4 • 3 12
2 • 4 8
_ = ___
3 • 4 12
Answer:
Option D. No solutions
Step-by-step explanation:
we have
-----> equation A
----> equation B
Multiply by -3 both sides equation A

-----> equation C
Compare equation B and equation C
Equation B and equation C are parallel lines with different y-intercept
<u><em>Verify</em></u>
For x=0
<em>Equation C</em>
----->
The y-intercept is the point (0,0.5)
Equation B
----->
The y-intercept is the point (0,-0.5)
therefore
Lines do not intersect
The system has no solution
