Can you guys answer like this in algebra
Total is 18
There are three people Gaston, Kari and Soonja
Kari gets 2 times Gaston, Sonja gets 3 times Gaston, Gaston is unknown
Let Gaston be y
Kari is double Gaston which is 2y
Soonja is triple Gaston which is 3y
The equation will be: y + 2y + 3y = 18
Solution add all the y 6y = 18
Y = 18 ÷ 6
Y =3,
Answers
1)no.of cups of flour nedded=7 cups
Mary has cups of flours=4 cups
still the no.of cups needed=x
x+4=7
x=7-4=3 cups
2)12-7=5 more roses
3)14×x=168
14x=168
x=12
4)x+47=83
x=83-47=36
5)let x be the smallest number
x+x+2+x+4==105
3x+6=105
3x=99
x=33
x+2=35
x+4=37
6)let x be the smallest number
x+x+2+x+4==135
3x+6=135
3x=129
x=43
x+2=45
x+4=47
7)for one hour bike rent=15+8=23 dollars
Mary paid=47 dollars
no.of hours the bike rented=x
=x×23=47
=23x=47
=x=2.04
=2 hours 4 minutes
9)let the no.of games played by Alex in the last weekend=x
no.of games played by Sam in the last weekend=x+4
total no.of games they played in the last weekend=12
x+x+4=12
2x+4=12
2x=8
x=4
Alex played 4 games in the last weekend.
Sam played 8 games in the last weekend.
10)let the normal rate be x
over time worked rate=x×5/4=5x/4
joel worked 40 hours at normal rate and 12 hours over time
So his salery=(40×x)+(12×(5x/4))=660
40x+15x=660
55x=660
x=12
So,his normal rate for 1 hour= $12
Hope it helps you.
