Given : Expression 2\times b or 2b.

To find : Create a model to show expression ?

Solution :

2\times b or 2b

Step 1 - First we create a model of b.

Ste 2 - The expression 2(b) tells us that we have 2 of the (b)’s.

Create a model that shows 2 groups of (b).

Step 3 - Count b’s i.e. 2b's

Step 4 - We grouped together the 2’s.

Step 5 - Write the expression as

2\times b=2b

Kim is painting the outside of her house, Joe will charge her $250 plus $14/hr. Bill will charge her $22/hr. How many hours the
prohojiy [21]

Answer:

Step-by-step explanation:

This is an inequality problem.  If we want Joe's service to be cheaper, then the inequality is set up like this:

14x + 250 < 22x

where x is the number of hours.

Solving we get

250 < 8x so

31.25 < x or equivalently,

x > 31.25

That means that all hours less than 31.25 would put Bill's as the cheaper service.  All hours greater than 31.25 would put Joe's as the cheaper service.

Maria can paddle her canoe 2 miles upstream against the current in the same time it would take her to paddle 6 miles downstream.
BigorU [14]
The answer is 2. Imagine Maria can paddle 4 miles in either direction if there was no current in 2 hours. But if we add the current then we would subtract 2 when she goes upstream so she would get 4-2 which is 2 miles. And would get an extra 2 miles going downstream. So 4+2= 6 miles.

So the speed of the current is 2 mph.

Hope this helps!
