There are many ways to do this, if you wanted to write a numerical expression for: Lauren had $7 she babysits for three hours and earned $8.50 per hour, you would write 7+3x8.50=M. It is much shorter and makes much more sense to write this expression than to write a whole story
2x = 15 + x
First, our goal is to get 'x' to equal something by itself. To do so, we will have to do everything on one side. Let's subtract 'x' from each sides.

Second, our next step is to subtract '2x - x'. Since 'x' is basically considered (1), it will equal 'x'.

Answer:
Answer:
Round off to closest value.
Step-by-step explanation:
In order to remove the requirement for change, every time the client buys a product for $0.20 the random number that lies between 0 and 1 would be produced also the same would be rounded to the closest value i.e. 0 or 1. In the case when 0 arise so the customer would not have to pay any amount but if 1 arise so the customer have to pay $1. So this type of method would remove the requirement for a minor change
(4,10) im 70% sure its true lol
Distribute (2x+y) throughout (4x^2-2xy+y^2). You should get
8x^3-4x^2y+2xy^2+4x^2y-2xy^2+y^3
Simplify and collect like terms and you should get 8x^3+y^3
