Answer:
6
Step-by-step explanation:
Note: f(x) = y
f(x) = 2x + 2 x = 2
Step 1: Plug in 2 into x.
f(x) = 2(2) + 2
Step 2: Then multiply 2 times 2.
f(x) = 4 + 2
Step 3: Add.
f(x) = 6
Let the distance of Judy from intersection is x and distance of Jackie from intersection is y.
We convert the given information to equations, step by step.
Point 1: When Jackie is 1 mile farther from the intersection than Judy.
This means y is 1 mile more than x.
So,
y = 1 + x
Point 2: The distance between them is 2 miles more than Judy’s distance from the intersection.
Distance between is x+ y.
So, x+y is 2 miles more than y.
x+y = y + 2
⇒
x = 2
From point 1 we have:
y = 1 + x = 1+ 2 = 3
So,
Distance of Judy from intersection is 2 miles and distance of Jackie from intersection is 3 miles.
Answer:
Step-by-step explanation:
Given:
For every 1/2 of an hour that the turtle is crawling, he can travel 3/20 of a mile
Question asked:
At what unit rate is the turtle crawling?
Solution:
As here<u> time taken is given</u> and the <u>distance traveled is also given </u>and hence we will apply speed and distance formula to find rate of crawling of turtle.
Time taken by turtle = 
Distance which can be traveled by turtle = 
Therefore, the rate at which the turtle is crawling is
