Answer:
The car travel 44 feet during the driver`s reaction time.
Step-by-step explanation:
The sentence "If the driver`s reaction time was 34 of a second" has to be changed as "If the driver`s reaction time was 3/4 of a second"
If the driver drives at a speed of 40 miles per hour, it means s/he travels
40 × 5280 = 211200 feet per hour.
1 hour is 60 minutes and 1 minute is 60 seconds.
That is, 1 hour is 3600 seconds.
Therefore the driver travels
feet in a second.
And since the reaction time is
of a second, the car travels
feet during the reaction time.
Answer:
(3, - 1 )
Step-by-step explanation:
Given the 2 equations
x - 3y = 6 → (1)
2x + 2y = 4 → (2)
Rearrange (1) expressing x in terms of y by adding 3y to both sides
x = 6 + 3y → (3)
Substitute x = 6 + 3y into (2)
2(6 + 3y) + 2y = 4 ← distribute and simplify left side
12 + 6y + 2y = 4
12 + 8y = 4 ( subtract 12 from both sides )
8y = - 8 ( divide both sides by 8 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = 6 + 3(- 1) = 6 - 3 = 3
Solution is (3, - 1 )
