Answer:
133.33 mph
Step-by-step explanation:
The small trick is to notice the time. Is it 8:00 AM the same day. We don't know, but we will assume it is.
So the truck was on the road for 2 hours.
The car was on the road for 2 - 1/2 = 1 1/2 = 1.5 hours.
The distance travelled was 200 miles
Solution
d = r * t
200 = r * 1.5
200/1.5 = r
r = 133.33 miles / hour
The noise you hear is a siren trying to catch up to the car.
The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.
<h3>Inequality functions</h3>
Inequality are expressions not separated by an equal sign, Given the inequality;
2.1 + (-1.2x) ≥ 8
The sign ≥ means greater than or equal to
The expression 2.1 + (-1.2x) ≥ 8 can also be expressed as 2.1 - 1.2x ≥ 8
The best interpretation is that the sum of 2.1 and –1.2 times a number is greater than or equal to 8.

Answer:
x = - 1, y = - 1
Step-by-step explanation:
- 6x + 5y = 1 (1)
6x + 4y = - 10 (2)
Add (1) to (2) sides by sides
9y=-9
Dividing both sides by 9
y = -1
Substitute y = -1 into equation (2)
6x + 4(-1) = - 10
6x = -6
x = - 1
