The answer is (1,3) because when you graph it you can see it is on the parabola.
Answer:
45 miles.
Step-by-step explanation:
Given that the:
Total distance covered = 390 miles
Total time = 8 hours
Let the distance covered along the local way = L
And the distance covered along the highway = H
Along with local way,
Speed = distance/ time
20 = L / T
T = L /20 .... (1)
Along the highway,
Distance covered H = 390 - L
Let the time = t
Speed = distance/time
60 = (390 - L)/t
t = ( 390 - L)/60
But total time = T + t
That is
8 = L/20 + (390 - L)/60
The LCM at right hand side will be 60
8 = ( 3L + 390 - L )/60
Cross multiply
480 = 2L + 390
Collect the like terms
2L = 480 - 390
2L = 90
L = 90/2
L = 45 miles.
Therefore, the distance Minato drive along local roads is 45 miles

Step-by-step explanation:
9x2 − 12x + 4 = 18 - 12x + 4 = 22 - 12x = 2(11 - 6x)
length of 1 side = ± sqrt 2(11-6x) (rej neg value)
Answer:
77 children and 186 adults
Step-by-step explanation:
After a LONG time testing out numbers, I finally found two numbers. What I did was used the equation 3x + 5.5y = 1254. I kept filling in two numbers that can add to 263. For example, I filled in the variables with 77 and 186. Like this: 3(77) + 5.5(186) = 1254. 77 times 3 equals 231 and 186 times 5.5 equals 1023. Add those two numbers together to get 1254. So, there were 77 children and 186 adults.
