Answer:
3 47/50
Step-by-step explanation:
You have to make the denominators be the same, in this case, it would be easy to make it 100.
Then the expression would look like 3 24/100 + 70/100
The answer is 3 94/100
When simplified, itI is 3 47/50.
Hope this helps!!
Let me know if I'm wrong...
The distance the bird has flown by the time Alice and Bob meet is 40 feet.
Given that the distance between Alice and Bob is 1000 feet and their running speed is 10 feet per second and the speed of bird is 20 feet per second.
Distance equals speed multiplied by time.
Distance between Alice and Bob=1000 feet.
Distance between the bird and Bob=1000 feet.
Speed of Alice and Bob=10 feet per second.
The combined speed of Alice and Bob=20 feet per second.
Since the two are running directly toward each other the distance each will cover at the meeting point is 50 feet (1000/20)
The time covered at the meeting point=20 second (1000/50)
Speed of the bird=20 feet per second.
The distance covered by the bird towards Bob at their meeting point is 40 feet(20 feet*20 seconds).
Hence the distance the bird has flown by the time Alice and Bob meet is 40 feet.

Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
Step 1: Write equation
-72 = 3(-4x - 8)
Step 2: Solve for <em>x</em>
<u>Distribute 3:</u> -72 = -12x - 24
<u>Add 24 to both sides:</u> -48 = -12x
<u>Divide both sides by -12:</u> x = 4
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-72 = 3(-4(4) - 8)
-72 = 3(-16 - 8)
-72 = 3(-24)
-72 = -72
