You need to write an essay that has at least 500 words. You have written 280 words so far. Write and solve an inequality that represents the number of words w that you have left to write.

500=280-w     w=−220

Step-by-step explanation:

Let's solve your equation step-by-step.

500=280−w

Step 1: Simplify both sides of the equation.

500=280−w

500=280+−w

500=−w+280

Step 2: Flip the equation.

−w+280=500

Step 3: Subtract 280 from both sides.

−w+280−280=500−280

−w=220

Step 4: Divide both sides by -1.

-w/-1=220/-1

w=−220

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
