3/x=15/40
solve for x
multiply both sides by x
3=15x/40
multiply both sides by 40
120=15x
dvide both sdies by 15
8=x

the answer is 8

or you could simplifyy 15/40 to get 3/8

How would you graph the solution set of x - 6 < -3?

mezya [45]

Answer:

Draw an open circle on 3 and shade to the left.

Step-by-step explanation:

Given:

The inequality given is:

$x-6$

In order to solve for 'x', we add 6 on both sides of the inequality. This gives,

$x-6+6$

Therefore, the solution is 'x' less than 3.

So, 'x' includes all the values that are less than 3 and excluding 3 as the inequality sign is less than.

So, on a number line, the values that are less than 3 are to the left of 3. So, we shade to the left. Also, 3 is excluded from the solution. So, we use an open circle as shown below.

So, the first option is the correct option.
