Answer:
The answer to your question is 9 adults and 2 children
Step-by-step explanation:
Data
adult ticket = $22
children ticket = $15
Total people= 11
total cost = $228
Number of adults = x = ?
Number of children = y = ?
Process
1.- Write equation to solve the problem
x + y = 11 Equation l
22x + 15y = 228 Equation ll
-Solve Equation l by x
x = 11 - y Equation lll
-Substitute equation lll in equation ll
22(11 - y) + 15y = 228
-Solve for y
242 - 22y + 15y = 228
-Simplify like terms
-7y = 228 - 242
-7y = -14
y = -14/-7
y = 2
-Find x
x = 11 - 2
x = 9
2.- Conclusion
There were 9 adults and 2 children.
Answer:
Step-by-step explanation:
Two angles that are directly across from each other when two lines intersect are called vertical angles. Vertical angles are ALWAYS congruent to each other. Very good thing to know when it comes to proving triangle congruency.
We have to set up 2 equations:
A) x + y = 10 liters
B) .05x + .25y = 10 * .10
Multiply equation B) by -4
B) -.2x - y = -4 then add to equation A)
A) x + y = 10 liters
.8x = 6 liters
x = 7.5 liters of 5%
y = 2.5 liters of 25%
Hey there, 2 out of 5 is 2/5. There are a lot of fractions that is equivalent to 2/5, so I am only going to give you 3, 2/5=4/10, 6/15, and 8/40, 2*2=4 and 5*2=10.
