100 notes were altogether
<em><u>Solution:</u></em>
Given that ratio of the number of $2 notes to the number of $5 notes was 4 : 1
number of $2 notes : number of $5 notes = 4 : 1
Let 4x be the number of $ 2 notes
Let 1x be the number of $ 5 notes
Given that total value of notes is $ 260
Therefore,
$ 2 (number of $ 2 notes ) + $ 5(number of $ 5 notes ) = $ 260
$ 2(4x) + $ 5(1x) = $ 260
8x + 5x = 260
13x = 260
x = 20
<em><u>Thus number of notes altogether is given as:</u></em>
4x + 1x = 4(20) + 1(20) = 80 + 20 = 100
Thus 100 notes were altogether
7 games.
18×7=126
483+126=609
21×7=147
462+147=609
After 7 games each will have 609 points.
Answer: 0
To find this answer, we replace x with 0 in the g(x) function
g(x) = -2x
g(0) = -2*0
g(0) = 0
2x+3=3
I you're looking for x...
2x+3=3
-3 -3
2x=0
/2 /2
x=0
