The cost of adult ticket is $7 and child ticket is $4.
Step-by-step explanation:
Let,
Price of one adult ticket = x
Price of one child ticket = y
According to given statement;
2x+7y=42 Eqn 1
3x+11y=65 Eqn 2
Multiplying Eqn 1 by 3
Multiplying Eqn 2 by 2
Subtracting Eqn 3 from Eqn 4
Putting y=4 in Eqn 1
Dividing both sides by 2
The cost of adult ticket is $7 and child ticket is $4.

Step-by-step explanation:
3 tickets = $16.50
1 tickets = $16.50/3
= $5.5
2 tickets = $2×5.5
= $11.00
There would not be two Y-Intercepts, so it is either B or C
Since you can determine the intercept through the equation y=mx+b and b in this equation is 600 so the answer is C
Answer:
Step-by-step explanation:
The graph below shows what you are given. The equation is actually y = x-4
.Answer:
The answer is below
Step-by-step explanation:
The patient loses 1 kg every week for 5 weeks.
1 kg = 2.2 lbs
Therefore the patient loses 2.2 lbs every week for 5 weeks.
a) The weight of the patient after 5 weeks = 245 lbs. - (5 weeks)(2.2 lbs per week)
The weight of the patient after 5 weeks = 245 lbs. - 11 lbs. = 234 lbs.
b) The weight of the patient after 5 weeks = 245 lbs. - 11 lbs. = 234 lbs.
1 kg = 2.2 lbs.
234 lbs. = 234 lbs. * 1 kg per 2.2 lbs. = 106.36 kg
