Answer:
Number of minutes per lap = 2.25 minute
Number of lap per minute = 0.444 lap (Approx)
Time taken for 15 lap = 33.75 minutes
Step-by-step explanation:
Given:
Number of laps = 4
Time taken = 9 min
Computation:
Number of minutes per lap = 9 / 4
Number of minutes per lap = 2.25 minute
Number of lap per minute = 4 / 9
Number of lap per minute = 0.444 lap (Approx)
Time taken for 15 lap = 15 x 2.25
Time taken for 15 lap = 33.75 minutes
To solve this problem, you'll want to substitute the variables for the values you are given and follow the order of operations. Let's substitute first, shall we?
xz becomes 4 times 1.
4y becomes 4 times 2.
2z becomes 2 times 1.
Now that we have everything substituted in, we have our new equation.
4*1(4*2 - 2*1) With the asterisks representing the multiplication sign.
Now, solving those first easy problems as the first step, we get..
4(8-2)
Remember to follow order of operations! Do the problem in the parentheses first, 8-2.
Now we have 4(6).
Assuming the problem is exactly how you wrote it and you are supposed to multiply the two numbers, your answer is 24.
Answer:
44+22=x or x-22=44
Step-by-step explanation:
X is the unknown, and so x decreased (minus) 22 is(equals) 44, so x-22=44.
