16 is the original distance her dance class was from home
The y intercept is when x = 0 so it is:-
8(0) + y = 8
0 + y = 8
y = 6 <------- y-interdept
x intercept is when y = 0 so:-
8x + 0 = 8
x = 1 <-------- x intercept
you divide 29:11= 2 7/11
so you have 2 full vans and one with 7 students.
so yes the answer is 7
First, to make things easier, let's turn 5/4 into a decimal given a second is equal to 1000 milliseconds.
5/4 = 1,25
1,25 * 1000 = 1250 milliseconds = 1.25 seconds
So, we've found that 45 yards can be covered in 1.25 seconds. Now we'll use the rule of 3:
45 - 1.25
80 - x
Now we solve:
(80 * 1.25) / 45 = x
100 / 45 = x
2,22... = x
So, according to our answer, 80 yards can be covered in 2,22 seconds, which in fractions would be:
