Answer:
I know you said no guessing, but I'm assuming it's the first one, F.
Because Lilah runs 105 m in 35 s, her average velocity is
(105 m)/(35 s) = 3 m.s
In terms of distance versus time, the equation that models the velocity is
m = 3s
where
m = distance, m
s = time,s
If we create a table of distance versus time, it should look like this:
t (s) s (m)
---- ------
1 3
5 15
10 30
The answer choices given are
a. m = 3s
b. m = 35s
c. s = 3m
d. s = 35m
where m = distance, meters
s = time, s
Answer:
Choice a. agrees with our model, and it is the correct choice.
That is,
s: 1 5 10
m: 3 15 30
The cost of one pizza is $8.5
Step-by-step explanation:
Let,
Cost of one pizza = x
Cost of one bread stick = y
According to given statement;
3x+2y=29.50 Eqn 1
2x+3y=23 Eqn 2
Multiplying Eqn 1 by 2
Multiplying Eqn 2 by 3
Subtracting Eqn 3 from Eqn 4
Dividing both sides by 5
Putting y=2 in Eqn 1
Dividing both sides by 3
The cost of one pizza is $8.5
