Ne4ueva [31]

Answer:

a = 3

Step-by-step explanation:

1) Simplify 5a - 9 + a to 6a - 9.

$6a - 9 = 9$

2) Add 9 to both sides.

$6a = 9 + 9$

3) Simplify 9 + 9 to 18.

$6a = 18$

4) Divide both sides by 6.

$a = \frac{18}{6}$

5) Simplify 18/6 to 3.

$a = 3$

Therefor, the answer is, a = 3.

Solve 4x - 3 = 18. Round to the nearest thousandth.

lorasvet [3.4K]

Answer:

$x=5.250$

Step-by-step explanation:

We have been given an equation $4x-3=18$ . We are asked to solve our given equation.

First of all, we will add 3 to both sides of our equation.

$4x-3+3=18+3$

$4x=21$

Now, we will divide both sides of our equation by 4.

$\frac{4x}{4}=\frac{21}{4}$

$x=5.25$

Upon rounding our answer to nearest thousandth (3 places after decimal) we will get,

$x=5.250$

Therefore, the solution for our given equation is $x=5.250$ .
