To determine the cost of each item, we need to set up equations. From the problem statement, we have three unknowns so we need three equations. We set up equations as follows:
let x cost of small pizzas
y cost of soda
z cost of salad
two small pizzas, a liter of soda, and a salad cost $14
2x + y + z = 14
one small pizza, a liter of soda, and three salads cost $15
x + y + 3z = 15
three small pizzas, a liter of soda, and two salads cost $22
3x + y + 2z = 22
Solving for x, y and z, we will have:
x = $ 5
y = $ 1
z = $ 3
Answer:
B. JK is longer than JL
Step-by-step explanation:
JK is 6, JL is 5. Therefore, JK is longer than JL.
Answer: t = 11.57s
The time taken for the Boxster to catch the Scion is 11.57s
Step-by-step explanation:
Given;
Speed of the boxster = 26.4m/s
Speed of the Scion = 15.6m/s
Assuming the starting point of 0 for the boxter, the starting point of the Scion would be 125.0m.
Given that;
Distance = speed × time
For the Boxster the distance travelled is;
d = 0 + 26.4t
For the scion the distance travelled is ;
d = 125 + 15.6t
Where t is the time.
Equating the two distance;
26.4t = 125 + 15.6t
26.4t - 15.6t = 125
t = 125/(26.4-15.6)
t = 11.57s
