Sue is correct.
When you plug in the values for x you find that Mark's answer for y should be 32/3 and Sue's answer for y should be 8 which is the answer she has.
Answer: X = 3 and Y = 0 3,0
The shadow lengthened by 2.25 ft.
<u>Step-by-step explanation:</u>
Height of the lamppost is not needed here.
We can write the ratio as,
5 /4 = x/5
25 = 4x
x = 25/ 4
Now it is not needed to find the length of the new shadow, and so, we need to find the length of the added shadow.
25 / 4 - 16/ 4 = 25 - 16 / 4 = 9/4 = 2.25 ft
Length of the new shadow is 25/ 4 = 6.25 ft
So length of new shadow - length of old shadow = 6.25 - 4 = 2.25 ft shadow lengthened
Answer:
It would cost $160 for 15 people to rent the bowling alley
Step-by-step explanation:
First, let's identify what we know:
1) It costs $100, just to rent the bowling alley.
2) We have to add $4 dollars, for every extra person.
3) The total cost can be found by using the expression 100 + 4n = x (n equals number of people, x equals total cost, 100 equals intial rent charge, and 4 equals the charge for each individual person)
So, just input 15 into the equation!
100 + 4(15) = x
100 + 60 = x
x = $160
