Answer:
Nine
Step-by-step explanation:
3 dollars for children tickets : x
5 dollars for adult tickets: y
Equation is:
3x+5y=57
Where 57 is the total amount spent
x+y=15
where 15 is the total number of tickets bought
3x+5y=57
5(x+y)=5(15)
___________________
3x+5y=57
5x+5y=75
minus the equations top to bottom=
-2x= -18
x= -18/(-2)
x=9
He bought a total of 9 children tickets

here's the answer to the question
Answer: C and D
(the solution is r is less than or equal to 2)
Answer is:
8/9
4 goes into 32 8 times
4 goes into 36 9 times
The value of X assuming that all intersecting sides meet at right angles is 5 yards
The given shape is made up of two rectangles. From the shape, we can deduce that:
15 = 10 + X
Next is to get the unknown value of X
Subtract 10 from both sides
15 - 10 = 10 + X - 10
15 - 10 = X
5 = X
Swap
X = 5yards
Hence the value of X assuming that all intersecting sides meet at right angles is 5 yards
