X+y= 26 and 4.75x + 2.25y= 83.50
y=26-x( substitute this into second equation for y and solve for x)
4.75x + 2.25(26-x)= 83.50
4.75x + 58.5-2.25x= 83.50
x= 10
Now solve for y by substituting your answer for x
10+ y= 26
y=16
Therefore, 16 tickets were purchased for kids and 10 for adults.
Answer:
x =1/12(1-√(97) )
Step-by-step explanation:
Step-by-step explanation:
l = 3x - 5
w = 2x + 9
perimeter = 2l + 2w = 2(3x - 5) + 2(2x + 9) =
= 6x - 10 + 4x + 18 = 10x + 8
area = l×w = (3x - 5)(2x + 9) = 6x² + 27x - 10x - 45 =
= 6x² + 17x - 45
You would form this inequality:
52 + 2x < (or equal to) 180
Then, solve as you would in an ordinary equation.
Subtract 52 from both sides of the sign. 180 - 52 = 128.
So, 2x is less than or equal to 128.
Divide 128 into two to get 64.
The height of the frame must be 64 inches.
Answer:-800
Step-by-step explanation: 10 times 10 is 100 plus another 100 is 200-1000 is -800 which is x
