Answer: the number of adult tickets sold is 400
the number of student tickets sold is 200
Step-by-step explanation:
Let x represent the number of adult tickets sold at the play.
Let y represent the number of student tickets sold at the play.
Adult tickets to a play cost $1.75 each and student tickets cost $1.25 each. If the income from the play was $1,700, it means that
1.75x + 1.25y = 1700 - - - - - - - - - -1
Suppose there are twice as many student tickets sold as adult tickets. This means that
y = 2x
Substituting y = 2x into equation 1, it becomes
1.75x + 1.25 × 2x = 1700= 1700
1.75y + 2.5y = 1700
4.25y = 1700
y = 1700/4.25 = 400
x = y/2 = 400/2 = 200
Answer:
Width of 6ft and length of 9ft
Step-by-step explanation:
The sandbox has a ratio of 2:3. If you plug the numbers in with the ratio, you can find the actual dimensions.
Let x be the length
Let y be the width
(Length)
2in / 3ft = 6in / (x)ft
2in / 3ft = 6in / <u><em>9ft </em></u>
(Width)
2in / 3ft = 4in / (y)ft
2in / 3ft = 4in / <em><u>6ft</u></em>
