Answer:

6.24

Step-by-step explanation:

A= 18.42g, B = 5.8g,C = 0.75g

Total = 18.42 + 5.8 + 0.75

What is 13x -4+100=180
Naddika [18.5K]

Answer: x = 6.46153846

Step-by-step explanation:

We are given the equation <em>13x - 4 +100 = 180</em>, and we must find the value of <em>x</em>. In order to do that get x on on one side by itself and a constant on the other side by itself.

This first step is to combine like terms. <em>13x</em> is by itself. <em>-4 + 100 = 96</em>. This gives us the equation <em>13x +96 = 180</em>.

In order to get <em>x </em>by itself, subtract 96 from each side of the equation. This gives us the equation 13x = 84.

Next, divide each side by 13 to find x. This gives us x = 6.46153846

13x - 4 +100=180

13x + 96 = 180

13x = 84

x = 6.46153856

Hope this helps! Have a nice day!

3a+11=7a-13 with shown work​
DaniilM [7]

3a+11=7a-13

move 7a to the other side

sign changes from +7a to -7a

3a-7a+11= 7a-7a-13( combine like terms)

3a-7a+11= -13

-4a+11= -13

move 11 to the other side

sign changes from +11 to -11

-4a+11-11= -13-11

-4a= -13-11

-4a= -24

divide both sides by -4 to get a by itself

-4a/-4= -24/-4

Answer: a= 6
