Ok, so you know that we can't divide fractions no matter what. The first thing you do is keep the first fraction, then change the divide sign to multiplication ( opposite of division is multi. ) and finallly flip the last fraction to 7/1 .
Here's a video to help you understand that method more ...

Step-by-step explanation:
Answer: a package of cookies cost $ 5 and each bag of chips cost $5
Step-by-step explanation:
Let x represent the cost of a package of cookies and y represent the cost of a bap of chips ,then from the first statement :
4x + 4y = 40
dividing through by 4 , we have
x + y = 10 ........................... equation 1
From the second statement
3x + 5y = 40 ..................... equation 2
Solving the system of linear equation by substitution method , from equation 1 , make x the subject of the formula , that is
x = 10 - y ................... equation 3
substitute x = 10 - y into equation 2 , we have :
3 (10 - y ) + 5y = 40
30 - 3y + 5y = 40
30 + 2y = 40
subtract 30 from both sides
2y = 40 -30
2y = 10
y = 5
substitute y = 5 into equation 3 , equation 3 becomes
x = 10 - 5
x = 5
Therefore ; a package of cookies cost $ 5 and each bag of chips cost $5
According to a center for disease control. We can’t compute the probability.
<u>SOLUTION:
</u>
Given that, According to a center for disease control,
The probability that a randomly selected person has hearing problems is 0.157.
The probability that a randomly selected person has vision problems is 0.096.
We have to find whether we can compute the probability of randomly selecting a person who has hearing problems or vision problems by adding these probabilities or not?
The answer is no, because hearing and vision problems are not mutually exclusive.
So, some people have both hearing and vision problems.
These people would be included twice in the probability.
Hence, we can’t compute the probability.
