37x + 45y = 7940
75x + 45y = 10,410
Since 45y is in both equations we can more easily transfer from first equation to 2nd equation.
In the first equation, subtract 37x from each side and you have 45y = 7940 - 37x. Replace the 45y in the second equation with (7940 - 37x).
Now you have 75x + (7940 - 37x) = 10,410
Simplify by combining 75x - 37x and you have 38x + 7940 = 10,410
Subtract 7940 from both sides and you have 38x = 2470.
Divide both sides by 38 and you have x = 65
To solve for y, take you first equation (or even the second one) and substitute c for 65.
(37 x 65) + 45y = 7940
2405 + 45y = 7940
Subtract 2405 from each side.
45y = 5535
Divide each side by 45 and you have y = 123
Regular tickets = $65
VIP tickets = $123
Sorry but I can’t see the picture
Answer:
Step-by-step explanation:
That composite figure is made up of a square and a quarter of a circle. We will first find the area of the square. Then we will find the area of the circle and divide it by 4.
Area of square = 1.6 × 1.6
Area of square = 2.56 m squared
Area of circle = (3.14)(1.6²) In case you forgot, the area of a circle is A = πr².
Area of circle = 8.0384
Divide that by 4 to get 2.0096.
Add 2.0096 to 2.56 to get the total area, which is
4.5696 or 4.6 rounded (choice D)
4.
A. 3x + 1.50y the variables are x and y
B. If x = 73 wristbands and 47 buttons then:
3(47) + 1.50(47)
141 + 70.5 = 211.5
There you go!!
I think you mean "ratio", not "raito." Ummm... The answer is 30 models that were sold
