set up equations
daren is 3 years older than tom
D = 3 + T
3 years ago leah will be 14 less than 3 times darren's age
L - 3 = 3(D - 3) - 14
L - 3 = 3D - 9 - 14
L = 3D - 9 - 14 + 3
L = 3D - 20
5 years ago, leah was 2 years less than 2 times tom
L - 5 = 2(T - 5) - 2
L - 5 = 2T - 10 -2
L = 2T - 10 - 2 + 5
L = 2T - 7
find leah's current age
set L = 3D - 20 and L = 2T - 7 equal to each other
3D - 20 = 2T - 7
plug 3 + T into D using the equation D = 3 + T
3D - 20 = 2T - 7
3(3 + T) - 20 = 2T - 7
9 + 3T - 20 = 2T - 7
T = - 7 - 9 + 20
T = 4
plug T back into L = 2T - 7 to find leah's current age
L = 2T - 7
L = 2 * 4 - 7
L = 8 - 7
L = 1
leah's age 4 years from now
add 4 to leah's current age
1 + 4 = 5
b. Do you think it is possible for 15,000 to ride the thrill ride in 1 day? Explain.
Answer: a) The least number of rides needed for 15000 people is 1250.
b) No
Step-by-step explanation:
Since we have given that
Number of people an amusement park holds = 12 people per ride.
Number of people is needed for the least number of rides = 15000
Let the number of rides be 'x'.
a) So, our inequality will be
Hence,the least number of rides needed for 15000 people is 1250.
b) Do you think it is possible for 15,000 to ride the thrill ride in 1 day? Explain.
Since there is 1250 rides, and
If we assume that the amusement park is open for 8 hours.
Then, each ride takes
But each rides takes atleast 5 minutes.
So, it is not possible to ride the thrill ride in 1 day.
10 canoes will they need.
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Total candidates = 23+ 2 + 3 = 28
and, Each canoe can hold 3 people.
So, number of canoes will they need
= 28/3
= 9.333
Hence, 10 canoes will they need.
