You have to prove your work. It can be difficult... But I believe in you! The way to do it, is to do the math out. If you have 2 different exponents, then you'll have to create multiple equations to solve, and use them to find what Y or X is.
Example:
4y + 8x = 112
Lets do y first. In order to do this, you need to get Y alone.
4y = 112 - 8x
Then, we divide.
y = 28 - 2x
Then insert your y value into the equation: 4(28 - 2x) + 8x = 112
Solve that, and you will have your x value! Then plug in your x value to find the y value. After that, insert both to check your work. There you go! That's the answer to finding the x. Then plug in your new x value, and complete the equation! Make sure to show all of your work!

These are the first four terms of a sequence.

Answer:

2+3n

Step-by-step explanation:

This question is based on a topic called sequence and series,under which we have the arithmetic progression

The formula for arithmetic progression is a+(n-1)d

In which a is the first number,n is the nth term and d is the difference

Back to the question

a=5,n=it's not given,d=3

Using the general formula

a+(n-1)d

5+(n-1)3

Open the bracket first

5+3n-3

Collect like terms

5-3+3n

2+3n

The answer is 2+3n

And it can be solved further only if we are given the value of n...the question even stated that we should solve in terms of n

Therefore the answer is 2+3n

Phillipe has 320 pieces of

tankabanditka [31]

The number of candies that will be left over after giving everyone an equal amount is equal to 23.

Given the following data:

Total number of candy = 320 pieces

Number of classmates = 27 classmates

To calculate the number of candies that will be left over after giving everyone an equal amount:

In this exercise, you're required to determine the number of candies Phillipe would have as left over after giving everyone in his class an equal amount of candies.

<h3>How to solve this word problem.</h3>

Thus, we would find the number of times 27 would divide 320 without any remainder.

$\frac{320}{27} = 11 \frac{23}{27}$
