(? x 3) - 3 = 15<br><br>help pls and i need the steps :/​
marishachu [46]

Answer:

4

Step-by-step explanation:

Lets make x be the ? in the equation.

That becomes (x x 3) - 3 = 15.

First you have to add 3 on both sides. After doing that it gets to (x x 3) = 15 - 3.

Then you simplify it to 3x = 12.

Now you divide 3 on both sides. That gets to x = 4 after doing it.

Hope this helped! If not, please let me know! <3

What is 1/5 in mixed number and can 1.50 be divided into 0.3
musickatia [10]
Hello. 

1/5 in a mixed number is 5. There isn't any mixed number. It's just a whole number. 1.5 divided by 0.3 = 5.

Have a great day! :)

Solve the following inequality for w then simplify <br> -w+9&gt;6w+8
Alla [95]

Answer:

\displaystyle (-\infty,\frac{1}{7})

Step-by-step explanation:

<u>Inequalities</u>

To solve the inequality:

-w+9>6w+8

We need to perform the required operations on both sides of the inequality to have the variable w isolated.

First, we subtract 9:

-w+9>6w+8

-w>6w+8-9

Subtracting 6w:

-w-6w>+8-9

Operating:

-7w>-1

Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:

\displaystyle w

Operating:

\displaystyle w

Solution:

\mathbf{\displaystyle (-\infty,\frac{1}{7})}

Alicia is writing the program for a video game. For one part of the game, she uses the rule
astra-53 [7]

As the mapping suggests, the first (x) coordinate is decreased by 3, and the second (y) coordinate is increased by 2. So, given the inputs, you have

(-2,0) \mapsto (-2-3, 0+2) = (-5,2)

(3,-4) \mapsto (3-3, -4+2) = (0,-2)

And yes, this rule is a function: it has a starting set (the domain), which is all possible couples (x,y), and a landing set (the codomain), which is again composed by the couples (x,y). Since for every point in the domain you have one and only one output, this rule is a function.
