Answer:
a) 4w + 16 = 50.
Step-by-step explanation:
The garden's length is obviously 8 feet longer than the width. If width were represented by w, the length would be w + 8.
We are calculating the perimeter, which is 2 times the length plus 2 times the width. That adds up to be 50.
2(w) + 2(w + 8) = 50
2w + 2w + 16 = 50
4w + 16 = 50
So, the answer is a) 4w + 16 = 50.
Hope this helps!

Answer: A) 3(10 - 5y) + 6y =12
Step-by-step explanation:
As per the question , the given system of linear equation :
Here , To solve the system of equations using substitution , Johanna isolates x in the second equation and writes
As per the substitution method , the next step is to substitute the isolated value of 'x' in first equation , thus the next step will become
Hence, the correct option is A) 3(10 - 5y) + 6y =12
Answer:
With this ratio in 12 h the amount of people that will watch the movie is 1,440.
Step-by-step explanation:
In order to compute how many people will see the movie in 12 hours we need to find the ratio per hour of people watching the movie. We were given the information that 360 people watched the movie in 3 h, to convert this value to people per hour we can divide the amount of people that watched the movie on that time by the total amount of time that passed. We have:
ratio = 360/3 = 120 people/h
We now multiply the ratio of people watching the movie by the length of time that we want to know, that is 12h. So we have:
amount of people = time*ratio = 12*120 = 1440
So you divide 50 by 2 so there are 25 before him
