If f(x) = 3x +9 x when f(x) = 30

den301095 [7]

Answer:

$x=5/2$

Step-by-step explanation:

When $f(x)=30$ , we have $3x+9x=30$ .

Combining like terms on the right side, we have $12x=30$ .

Finally, dividing by $12$ we get $x=30/12$ .

We note that $30=6*5$ and $12=6*2$ , so $30/12=5/2$ .

So, $\boxed{x=5/2}$ and we're done!

Jesse is saving the money he earns in his piggybank. He had already earned

spin [16.1K]

Answer:

Jesse will have $120.

Step-by-step explanation:

First you need to set up your equation. We know Jesse has $60 already and that he charges $15 per lawn. Your equation will look something like this:

15x+60=?

Then you plug in the 4 lawns he did:

15(4)+60=

Then you solve and get 120! :)

PS Parenthesis mean you are multiplying. Same thing as saying

15 x 4 + 60= 120

Can anyone help me solvethis problem its dealing with solving two-step equations. (If you know the answer please help me thank y

amid [387]

Answer:

Your answer will be x=11/2

Step-by-step explanation:

What you want to do first is

Subtract 1 from both sides

2x+1-1=12-1

Simplify

2x=11

Divide both sides by 2

$\frac{2x}{2} =\frac{11}{2}$

Simplify

$x=\frac{11}{2}$
