<em><u>Answer:</u></em>

x = 2

<em><u>Step-by-step explanation:</u></em>

In the equation 7.2x = 14.4, to find x, we first want to isolate the variable.

It would be a little easier if there were no decimals so:

7.2x = 14.4

We could multiply both sides by 10 to get rid of the decimals

7.2x * 10 = 14.4 * 10

72x = 144

We then can divide both sides by 72

72x/72 = 144/72

<u><em>x = 2</em></u>

= 16 · 1

1 · 8

= 16

= 2 · 8

1 · 8

= 2

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(16, 8) = 8

Subtract: 26 - 2 = 24

Given the functions f(x) = 7x + 13 and g(x) = x + 2, which of the following functions represents f[g(x)] correctly?
ololo11 [35]

Answer:

f[g(x)]= 7x + 27

Step-by-step explanation:

g(x) = x + 2,

f(x) = 7x + 13,

f[g(x)] means you substitute the value of g(x) into the variable of f(x);

Which is 7( x+2) + 13 = 7x +14 +13

= 7x + 27

What is 469.82 plus 8.5 sales tax
alekssr [168]
Hey!


The first step to solving this problem would be to multiply 469.82 by 0.085.

<em>New Equation :</em>
469.82 × 0.085 = ?

<em>Solution {New Equation Solved} :</em>
469.82 × 0.085 = 39.9347

Ignore the forty seven at the end of the solution. You're only going to need 39.93. Now we'll add 469.82 and 39.93. This is the sales tax plus the regular price. Which will then bring us to our total.

<em>New Equation :</em>
469.82 + 39.93 = ?

<em>Solution {New Equation Solved} :</em>
469.82 + 39.93 = 509.75

<em>So, 469.82 plus 8.5 sales tax is</em>  509.75.

Hope this helps!
