Jo makes 170 minutes call. There are 150 free ones
170 - 150 = 20
20 minutes are "what Jo has to pay"
Jo sends 182 texts. There are 150 free ones
182 - 150 = 32
32 texts are "what Jo has to pay"

Monthly charge = 16p, 13p for each extra minute, 15p for each extra text.
13(20) = 260p
15(32) = 480p

480p + 260p + 16 = 740p + 16

740p + 16 is your answer (if p = pounds, add 16 to it, i'm not sure what p                                                  stands for though. If it is cents, divide 100 from                                                740 and take out the p, then add total to 16 to get                                            answer.)

hope this helps

Solve for a <br> 9a² = 16a<br> College Intermediate Algebra
Fed [463]

We want to solve 9a² = 16a for a.

Because the a is on both sides, a good strategy is to get all the a terms on one side and set it equal to zero. Then we apply the Zero Product Property (if the product is zero then so are its pieces and Factoring.

9a² = 16a

9a² - 16a = 0                <-----subtract 16a from both sides

a (9a - 16) = 0               <-----factor the common a on the left side

a = 0   OR   9a - 16 =0   <----apply Zero Product Property

Since a = 0 is already solved we work on the other equation.

9a - 16 = 0

9a = 16                        <----------- add 16 to both sides

a = 16/9                       <----------- divide both sides by 9


Thus a = 0 or a = 16/9

Steph needs to help her parents put a fence around their pool. They want the fence to be square and want each side to measure 6
marin [14]

Answer:

14 meters

Step-by-step explanation:

Each side of the square fence = 6 meters

Perimeter of the square fence = 4 × length

= 4 × 6

= 24 meters

They already have 10 meters of fencing

How many more meters of fencing should they buy?

= Total meters - available meters

= 24 meters - 10 meters

= 14 meters
