Answer: see below

Step-by-step explanation  

Let    2 + a = 11 x

Let    35 - b = 11 y

Where x and y are any unknown integer

subtract the two equations

- 33 + a + b = 11 (x+y)

a+ b = 11 (x+ y) +33

a+ b = 11 (x+y) + 3 (11)

a+ b = 11(x+ y+3)

Which proves that a+b is a  factor of 11

Answer:

47. 1  5/8

48. 1  1/12

Step-by-step explanation:

<em>47. </em>

<em>First, convert the denominators to be the same.</em>

8  1/2 minutes, Ruby's mile time, can be converted to 8  4/8.

<em>Then subtract.</em>

8  4/8 - 6  7/8  = 1  5/8

<em>48.</em>

<em>Make sure the denominators are the same. Both denominators can be multiplied by 3 or 4 to become 12.</em>

1  1/4 can be multiplied by 3 to get 1  3/12. And 1  1/3 can be multiplied by 4 to get  2  4/12.

<em>Then subtract.</em>

2  4/12 - 1  1/3 = 1  1/12

Un auto viaja con una velocidad promedio de 84 kilómetros por hora. ¿En cuánto tiempo viaja 462 kilómetros?
timama [110]

The car takes the time 5.5 hours i.e.5 hours and 30 minutes to travel 462 kilometres when the car travels at average speed of 84 kilometres per hour

Given the average speed of the car is 84 kilometres per hour and the distance to be travelled is 462 kilometres and asked to find the time taken for the journey of 462 kilometres

To calculate the time taken for the journey we use the below-mentioned formula

speed=\frac{distance}{Time taken}

(speed)×(Time taken)=distance

Time taken=\frac{distance}{speed}

Time taken=\frac{462 kilometres}{84KMPH}

Time taken=5.5 hours i.e.5 hours and 30 minutes

As a result, the time spent on the car journey is 5.5 hours

Hence, It takes the time 5hours and 5 minutes to travel 462 kilometres
