Mathematics
1 answer:
Anton [14]4 years ago
4 0

Answer:

x=3

Step-by-step explanation:

8x-28-2x=-10

We move all terms to the left:

8x-28-2x-(-10)=0

We add all the numbers together, and all the variables

6x-18=0

We move all terms containing x to the left, all other terms to the right

6x=18

x=18/6

x=3

In a biathalon race you first ride a bicycle at an average speed of 21.8 mi/h for 16.5 miles, then you must run for another 5.5
mote1985 [20]

Answer:

6.6 mi/h

Step-by-step explanation:

Given,

For first 16.5 miles, speed is 21.8 miles per hour,

Since,

Time = \frac{Distance}{Speed}

So, the time taken in first time = \frac{16.5}{21.8}

Let x be the average speed in miles per hour for another 5.5 miles,

So, the time taken in second time = \frac{5.5}{x}\text{ hours}

∴ Total time taken in entire journey = \frac{16.5}{21.8}+\frac{5.5}{x}

Now, total distance covered = 16.5 + 5.5 = 22 miles,

Hence, the average speed for the entire race = \frac{22}{\frac{16.5}{21.8}+\frac{5.5}{x}}

According to the question,

\frac{22}{\frac{16.5}{21.8}+\frac{5.5}{x}}=13.8

22=13.8(\frac{16.5}{21.8}+\frac{5.5}{x})

22=\frac{227.7}{21.8}+\frac{75.9}{x}

22-\frac{117.7}{21.8}=\frac{75.9}{x}

\frac{361.9}{21.8}=\frac{75.9}{x}

\implies x = 6.56856\approx 6.6\text{ miles per hour}
