First step: multiply the 5(x3) and it will give you x15 or most commonly written as 15x. you should now have 15x-(-20).

Second step: since you cannot subtract -20 from 15x because it has a variable, the final answer is just 15x-(-20), or 15x+20.

Say you have 3 cakes. How many cakes would you have eaten if you ate 1/3 of the three cakes? One, you have eaten one cake, out of the three you have.

How many cakes do you have left if you eat 2/3 of the three cakes? Two, you have eaten 2 cakes, and have 1 cake left.

It is a similar approach here, except the confusing part is working "forward", when you really have to work "backward". If you have driven 30 miles, and you have driven 2 parts out of the trip when there is 3 parts of the trip, how many miles have you driven? Hint: Dividing 30 by 2 gives you what fraction of the distance to Jeff's grandmother?

Write a number y divided by 6 as an expression.
Alina [70]

Answer:

y ÷ 6.

Step-by-step explanation:

An expression is a combination of a number(s) and a variable.

Here, we simply need to write the expression from the word problem in mathematical form.

"Number" is unknown.

Variables are used to represent an unknown value.

(The variable in this expression is y).

The word problem says a number y divided by 6.

This simply means: y ÷ 6.
