Answer:

<u>Valterri's unit rate for Day 1 in minutes per lap is 3.5 or 3 minutes and 30 seconds.</u>

Step-by-step explanation:

Let's find Valterri's unit rate for Day 1 in minutes per lap, this way:

Total time = 1 hour, 13 minutes, and 30 seconds

Total time = 60 minutes + 13 minutes + 30 seconds

Total time = 73 minutes and 30 seconds

Total time = 73.5 minutes (30 seconds = 0.5 minutes)

Number of laps = 21

Valterri's unit rate for Day 1 in minutes per lap = Total time/Number of laps

Valterri's unit rate for Day 1 in minutes per lap = 73.5/21

<u>Valterri's unit rate for Day 1 in minutes per lap = 3.5</u>

Graph the system. Tell whether the system has one solution, no solution, or infinitely many solutions. y = –2x + 1 y = –2x – 3
Alchen [17]
Let's try the actual solution of the system

<span>y = –2x + 1
y = –2x – 3

Note that the slopes of the graphs of these two lines are the same:  -2.

That means that the lines are parallel to one another.

Only the y-intercepts (1 and -3) are different.

Since the 2 lines never intersect, the system has no solution.

The sum of three numbers is 54. The third number is 6 more than the first. The second number is 2 times the third. What are the
77julia77 [94]

Answer:

9, 30, and 15.

Step-by-step explanation:

Let the three numbers be a, b, and c.

The sum of them is 54. So:

a+b+c=54

The third number is 6 more than the first. In other words, c=a+6.

The second number is twice the third. In other words, b=2c.

Let’s write the second number in terms of a. Since b=2c, this means that b=2(a+6).

Let’s substitute them into our equation. So:

a+2(a+6)+(a+6)=54

Solve for a. Distribute:

a+2a+12+a+6=54

Combine like terms:

4a+18=54

Subtract 18 from both sides:

4a=36

Hence, the value of a is:

a=9

So, the first number is 9.

The third number is 6 more than the first, so the third number is 15.

The second number is twice the third. So, the second number is 30.

Therefore, our numbers are:

9, 30, and 15.
