Ok, so for this problem you want to get Y all by itself.
First you’ll want to move your X variables to one side. You do that by adding 2X to both sides of the equation. This will cancel out the -2X and it will turn the 16X into an 18X.
You’re equation is now,
18X+9=9Y
Next you’ll want to divide both sides by 9 so that you’ll get Y all by itself.
Your equation should look like this.
Y=2X+1!
And that’s your answer:) I hope this helped!

What is the ones digit of a number if its cube ends in 7
Ostrovityanka [42]

Well, I have never seen a question posed this way, but let's check it out by trial and error.

1^3 = 3

2^3 = 8

3^3 = 27 Hey! There's one. And the ones digit ends in 3.

Let's try another number that ends in 3 and see if it works as well.

13^3 = 2197 Wow. It works again. I never noticed this before, so you taught me something new.

I will test one more.

33^3 = 35937 Bingo. I think we have a winner.

For every 5 coins carmen gets ,she gives 2 to her brother Frankie.If carmen has 9 coins,howmany coins does Frankie have?
FrozenT [24]

Answer:

Frankie have 6 coins

Step-by-step explanation:

For every 5 coins Carmen gets ,she gives 2 to her brother Frankie

Out of 5 coins, Carmen given 2 to her brother Frankie

So Carmen has 3 coins and Frankie has 2 coins

Ratio of coins , Frankie to Carmen is

2: 3

We need to find the number of coins Frankie has if Carmen has 9 coins

ratio of Frankie to Carmen is x : 9

Now make a proportion and solve for x

\frac{2}{3} =\frac{x}{9}

Cross multiply it

2*9 = 3*x

18 = 3x

Now divide both sides by 3

so x= 6

Frankie have 6 coins

(3x – 1)(2x +9)<br> Multiplying polynomials
ad-work [718]

We can use the FOIL method to simplify.

= (3x – 1)(2x + 9)

= (3x * 2x) + (3x * 9) + (-1 * 2x) + (-1 * 9)

= 6x + 27x + (-2x) + (-9)

= 33x - 11

Hope This Helped! Good Luck!
