3x + 2y = $134
2x + 3y = $146
Using elimination to solve for x
9x +6y = 3*134 Multiplying 1st equation by 3
-4x -6y = -2*146 | Multiplying 2nd equation by -2
5x = 3*134 - 2*146
5x = $110
x = $22, the cost of the youth ticket
Put x= 22 Into An Equation Then Solve For y
3(22)+2y= 134
66+ 2y=134
Subtract 66
2y=68
Y= 34
CHECKING Answer ($34 being the cost of the adult ticket) y = (134-3*22)/2
3*$22 + 2*$34 = $66 + $68 = $134
Answer:
Y-12 + y =120 take 12 to the other side get 2 y = 132
Y=66 so y-12=x
X=54
Answer:
D(4) = 6
Step-by-step explanation:
Using the blue graph, find the y value when x =4
the y value is 6 when x=4
D(4) = 6
Answer:
1. 0.472
2. 0.25
Step-by-step explanation:
1. reduce the fraction with 3 = 1\4 + 2\9
write all numerators above the Least common denominator 36 =9 + 8\36
Add numbers = 17\36 and the alternate form is 0.472
2. Divide the numerator and denominator by three = 3 ÷ 3\12 ÷ 3 = 0.25
I can't do the others now I have an exam(sorry)
