Answer:
x +(2x + 3) = 33
Step-by-step explanation:
two equations can be derived from the question
c = 3 + 2x equation 1
c + x = 33 equation 2
where :
c = cappuccinos
x = lattes
make c the subject of the formula in equation 2
c = 33 - x equation 3
equate 3 and 1
x +(2x + 3) = 33
Kn + 4f = 9f
kn + 4f - 4f = 9f - 4f
kn = 5f
kn/5 = 5f/5
kn/5 = f.
f = kn/5 or
f = 1/5 (kn).
The correct answer is

You can find this by first starting with the original question.

÷

Now to solve a division problem with fractions, you can always flip the second one and turn it into multiplying.

*

Now we can multiply numerator by numerator and denominator by denominator.

Then of course, we need to simplify. Since both are divisible by 3, we can divide both numbers by 3.
Answer:
Its the one on the left
Step-by-step explanation:
You first find the average of the first two test scores. When you find the average, you add the two numbers together and then divide by two which gives you 89. You then plug in different scores above the number 89 and find the average of those (89 and x) to see which gives you an average of 92. It’s mostly a guess and check type of problem.
