Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis).
For this problem, let x be the number of children and y for adults. Formulate the equations: 1st equation, x + y = 3,200 and 2nd equation 5x + 9y = 24,000. Re-arrange 1st equation into x = 3200 - y. Then, substitute into 2nd equation, 5(3,200-y) + 9y = 24,000. Then, solve for y. The 16,000 - 5y + 9y = 24000. Final answer is, y = 2000 adults went to watch the movie.
It really depends on what month or year. but typically a month is 4-5 weeks so it's either 16 or 20 miles
Answer:
Step-by-step explanation:
(6 gal)/(4/7 fence) = (21/2 gal)/fence = (10.5 gal)/fence
Answer:
5/7
Step-by-step explanation:
3-1 2/7
3=21/7 (by multiplying denominator)
1 2/7=16/7 (by multiply 1 and 7. Then add to 2)
21/7 - 16/7 = 5/7
