Answer:
(a) The grass is not green.
(b) Nothing can be concluded about squirrels.
Step-by-step explanation:
(a) If squirrels cannot fly, then the you can conclude that the grass is not green, because if the grass was green, then squirrels would be able to fly.
(b) By discovering that the grass is not green, nothing can be concluded regarding squirrels. The statement says that squirrels can fly if the grass is green which doesn't necessarily mean that they can't fly if the grass is not green.

The first one 2/5
Step-by-step explanation:
Answer:
<h2>-4/3</h2>
Step-by-step explanation:
3x-12=12x
-12=12x-3x
-12=9x
-12/9=x
-4/3=x
x=-4/3
Answer:
Step-by-step explanation:
Let x represent the time that they spent biking at the first speed.
If the ride was six hours long, it means that the time they spent biking at the other speed is (6 - x) hours.
Distance = speed × time
For the first part of the ride, they biked at a speed of 7 mph. This means that the distance travelled during the first part of the ride is
7 × x = 7x
For part of the ride, they biked at a speed of 11 mph. This means that the distance travelled during the second part of the ride is
11(6 - x)
Since the total distance that the kids traveled is 54 miles, then
11(6 - x) + 7x = 54
66 - 11x + 7x = 54
11x - 7x = 66 - 54
4x = 12
x = 12/4 = 3
They spent 3 hours biking at the first speed.
They spent 6 - 3 = 3 hours biking at the other speed.
Answer:
12 vans
7 Buses
Step-by-step explanation:
I tried multiple versions but I finally got it right.
Since the buses can hold 25 students at a time I multiplied it by 7.
7 x 25 = 175
Then you'll need to find the remainder.
259-175 = 84
This number would be used to find the students going in the van
84/7= 12
So in total there would be 12 vans
and 7 buses
I hope this helps
