F(2)= -3(2)+9 = 3
f(0)= -3(0)+9 = 9
3f(2)-2f(0)
= 3(3)-2(9)
= -9
Answer:
- <u>Faisal will receive $ 241</u>
- <u>Ahmed will receive $ 482</u>
- <u>Walid will receive $ 723. </u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Profit Ahmed, Walid and Faisal made from selling used books = $ 1,446
Ahmed to receive double amount of Faisal
Walid to receive triple amount of Faisal
2. How much does each one receive?
- Let x to represent the amount Faisal to receive
- Let 2x to represent the amount Ahmed to receive (double amount of Faisal)
- Let 3x to represent the amount Walid to receive (triple amount of Faisal)
Therefore, we have:
x + 2x + 3x = 1,446
6x = 1,446
x = 1,446/6
x = 241 ⇒ 2x = 482 ⇒ 3x = 723
<u>Faisal will receive $ 241, Ahmed will receive $ 482, and Walid will receive $ 723. </u>
It would be 910,000 because your rounding up.
Answer:
había 18 DVDs al principio
Step-by-step explanation:
si procedemos desde el final del problema , sabemos que :
total que le quedaba después de darle los CDs a Juan - lo que fue para la hermana = lo que le sobró
x - x/3 = 6
2/3*x = 6
x= 6 * 3/2 = 9
por lo tanto tenia x=9 DVDs después de entregarle a Juan los suyos
también sabemos que
DVDs que tenia al principio - lo que fue para Juan = 9 DVDs
y - y/2 = 9
y/2 = 9
y= 18
finalmente había y= 18 DVDs al principio
