Express 40 over 16 as a mixed number in simplest form

We want to find out how many times 16 goes into 40.

It goes into 40 twice, with 4 leftover.

tim is choosing between two cell phone plans that same amount of free minutes. Cingular plane charges 39.99 per month with addit

VMariaS [17]

Answer:

100 minutes

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the total cost of the plan

we know that

<em>Cingular Plan</em>

$y=0.45x+39.99$ -----> equation A

<em>Verizon Plan</em>

$y=0.40x+44.99$ -----> equation B

To find out how many additional minutes will it take for the two plans to cost the same

Solve the system of equations A and B

Solve by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (100,84.99)

see the attached figure

therefore

For x=100 minutes

The cost for both plans is $84.99

Ava makes bead necklaces. She has a total of 6,048 beads. Each necklace has 24 beads. Her friend Maria says that’s the greatest

Andrews [41]

Answer:

She made the 6 into a five to make the 0 a 1 too early, because 24 can go into 60 twice, but in order to subtract the 8, you would then have to make the 6 into a 5 as well as the 0 into a 1.

Step-by-step explanation:

6048 divided by 24 is 252
