We let x the distance traveled by Car A and y the distance traveled by car B. The speed of car A can be represented as x/2.4 and for Car B is y/4. From the statement given, we can write an equation relating the speed of both cars.
x/2.4 = 22 + y/4
Since y = x, then:
x/2.4 = 22 + x/4
Solving for x, we obtain:
x= 132 meters traveled by both cars
Therefore, Car A has a speed of 55 mph.
Answer:
The solution set is {-8, 5}.
Step-by-step explanation:
a^2 + 3a – 40 = 0 .
We need 2 numbers whose product is -40 and whose sum is +3.
They would be + 8 and - 5, so we have the factors:
(a + 8)(a - 5) = 0
Now either a + 8 = 0 or a - 5 = 0, so:
a = -8 or 5.
Answer:
Player 1's position is Player 2's position reflected across the y-axis; only the signs of the y-coordinates of Player 1 and Player 2 are different
Step-by-step explanation:
Answer:
A= ( 5 x 3 ) x [(9-5)x3 divided by 2]
15+6
=21
P= 5+5+3+9
=22
