Answer:
80 students.
Step-by-step explanation:
Since there were 50 students, and 20 students wanted the chocolate icecream, that makes a proportion of 2/5. Then, there are 200 students in this whole seventh grade, and imagine that they have the same proportion of the 50 students. So, you should do 2/5 × 200, and the answer is 80.
I hope this helps you! ;)

Answer:</h3>
A. Slope = -0.4, Y-intercept = 6.4 ft
<h3>
Step-by-step explanation:</h3>
The "hours" numbers in the table are all 1 unit apart, so the difference of any adjacent "level" numbers is the slope:
(5.6 ft - 6 ft)/(2 h -1 h) = -0.4 ft/h . . . . . the slope
Backing that up one hour to 0 hours, we would add 0.4 to the level at 1 hour:
6 ft + 0.4 ft = 6.4 ft . . . . . . level at 0 hours (the Y-intercept)
Answer:
11 miles
Step-by-step explanation:
Do 8+3 or just count the number of spaces on the number line
Farmer Brown has 5 cows and farmer Green has 7 cows
Step-by-step explanation:
Let the no. of cows farmer brown has be 'b'
Let the no. of cows farmer green has be 'g'
Given that,
B+1 = G-1
G = B + 2
G+1 = 2(B-1)
G+1 = 2B - 2
G = 2B -3
B + 2 = 2B - 3
2 + 3 = 2B - B
B = 5
G = B +2
G = 5 + 2
G = 7
Farmer Brown has 5 cows and farmer Green has 7 cows
