adult ticket = 10
child ticket = 4
Step-by-step explanation:
for example…
- adult ticket = x
- child ticket = y
so that we get a system of equations
9x + 5y = 110…Equation 1
x + y = 14…Equation 2
solve the system of equations, this time I will use the Elimination and Substitution method
9x + 5y = 110
x + y = 14 (multiplied by 5)
↓↓↓↓↓↓↓
9x + 5y = 110
5x + 5y = 70
___________ _
4x = 40
<u>x = 10</u>
to find value of y subtitute x to one of Equation. for example from second Equation…
x + y = 14
10 + y = 14
y = 14 - 10
<u>y = 4</u>
∴ So, the number of each ticket was she bought is <u>10 adult ticket</u> and <u>4 child </u><u>ticket.</u>
Answer:
V= 175 centimeters cubed
V= 126 inches cubed
Step-by-step explanation:
<u>1st question:</u>
V1=2×5×5= 50cm cubed
V2=2×5×5= 50cm cubed
V3= 5×3×5= 75cm cubed
V= 175 centimeters cubed
<u>2nd question:</u>
V1=3×3×2= 18in cubed
V2= 2×3×2= 12in cubed
V3= 6×8×2= 96in cubed
V= 18+12+96
V= 126 inches cubed
