Y is six more than x divided by three <br><br> turn it into an expression (y=mx+b format)
Snowcat [4.5K]

We always start from right side in order of operation in any equation

we can set up equation as

step-1:

x divided by three

we can write as

=\frac{x}{3}

step-2:

six more than x divided by three

so, we get

=\frac{x}{3}+6

step-3:

y is six more than x divided by three

so, we get

y=\frac{x}{3}+6

and this is in y=mx+b form

so, we have

y=\frac{x}{3}+6...............Answer

Which of the following could not be a value of x?<br> a -10<br> b-9<br> c-10.5<br> d-9.5
maw [93]

We know that sum of two sides in any triangle must be greater than the measure of third (longest) side otherwise triangle will not be formed.

According to picture longest side is 18

So this triangle must follow inequality

9+x>18

or 9-9+x>18-9

or x>9

that means value of x must be more than 9.

choices a, c, d are greater than 9 except choice b

Hence choice B-9 is the final answer.
