Answer:

2(2x + 1) = 30 \\ 4x + 2 = 30 \\ 4x = 30 - 2 \\ 4x = 28 \\ x =  \frac{28}{4}  \\ \boxed{ x = 7}

  • <u>x = 7</u> is the right answer.

X plus 1/3 equals nine enter your answer in the box in simplest form
LekaFEV [45]


= > x + \frac{1}{3} = 9



\text{Add} \: - \frac{1}{3} \: \text{ on both sides ,}



= > x + \frac{1}{3} - \frac{1}{3} = 9 - \frac{1}{3} \\ \\ \\ \\ = > x = \frac{(9 \times 3) - 1}{3} \\ \\ \\ \\ = > x = \frac{27 - 1}{3} \\ \\ \\ \boxed{ \bold{= > x = \frac{26}{3} }} \\ \\ \\ or , \boxed{ \bold{ \: x = 8. \bar{6}}}




Hence,


Value \: \: \: of \: \: x \: \: is \:  \frac{26}{3} \: \: \: or \: \: \: 8. \bar{6}

How do I do this activity, help is appreciated
Kitty [74]
This is fairly easy, all you need to do is write the ordered pairs for each graph, for these there are 5 ordered pairs for both.

In order to create the ordered pair all you need is this 'formula' of (x, y)

In the first graph 'input' would be the x value and output is the y value. So all you do is plug them into the formula.

(-10,-20)
(-5,-10)
(0,0)
(5,10)
(10,20)

Those are all the ordered pairs for graph A. Now just do the same thing for graph B.

Use properties of equality to find the value of x in the equation 12(5x-4.5)=36
lukranit [14]

Answer:

x= 1.5 Hope that helps!

Step-by-step explanation:

1. 12(5x-4.5)=36 First Divide both by 12 5x-4.5-36/12 = 3

2. 5x-4.5=3 add 4.5 to both sides

3. 5x= 3+4.5 = 7.5

4. 5x=7.5 divide both sides by 5 x=7.5/5= x=1.5

So, x=1.5 would be your answer. Can you make me Brainliest Please
