Samantha Cruz has 200 coins (quarters and dimes). She has $44.00. Write a system of equations and determine how many quarters= and dimes= she has

Step-by-step explanation:

how many coins:  d + q = 200

value of the money  .10d + .25q = 44

(ten cents for each dime and 25 cents for each quarter)

Now to solve by elimination:

1)multiply the first row by -10 so that the dimes will cancel out.

-.10d + -.10 q = 20   (don't do anything to second row)

.10d +  .25q = 44

2) now add those up.

the dimes cancel out.

.15 q = 64

that does not divide evenly so there is something wrong with this problem.

it's

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
