Answer: 
Step-by-step explanation:
We need to apply the following identity:
Then, applying this, you know that for 
:
We need to remember that:
and 
Therefore, we need to substitute these values into .
Then, you get:
X + 4x = 40
5x = 40
5x/5 = 40/5
x = 8
1x 8 = 8
4x 8 = 32
Check=
8 + 32 = 40
The numbers are 8 and 32
X=2t
y=1-t
t=x/2
y=1-x/2
y=(-1/2)x+1
Answer:
81.75
Step-by-step explanation:
75*1.09 = 81.75
If you have 1/5 and 2/3, you need a common denominator to even do anything. So three and five both go into 15, so then you do 2 times 5, cause 3 times 5 is 15. And 1 times 3, cause 3 times 5 is 15. So you end up with 3/15 as produce, and 10/15 as vegetables. So, then you divide the fractions, 1/5 divided by 10/15, which is the same as 1/5 times 15/10. So your answer is 3/10 of the produce is vegetables.
