Question

Eight increase by the product of a number and 6 is at least 18?

Use the variable b for the unknown number.

Answer 1

Here it is given that the unknown variable is b. So its product with 6 is 6b.

And 6b increased by 8 is

`6b+8`

And it is atleast 18.

So we will get

`6b+8 \geq 18`

Now we have to solve for b. ANd for that, first we subtract 8 to both sides

`6b\geq 10`

Now we divide both sides by 6

`b \geq (10)/(6)`

`b \geq (5)/(3)`
