This becomes $678\times45=30510$

Now, 67.8 has 1 decimal point and 0.45 has 2 decimal places.

Therefore, the answer will have 3 decimal places.

This makes the answer as 30.510.

Answer:

Bob's typing speed is 39 words per minute.

Bill's typing speed is 58 words per minute.

Step-by-step explanation:

Given : 

Bill can type 19 words per minute faster than bob. their combined typing speed is 97 words per minute.

To Find : 

Bobs typing speed

Solution : 

Let the bobs typing speed is x

According to the given question :

Bobs typing speed is x

Bill's typing speed is 19+x

Their combined speed is 97 words per minute.

Solving value x : 

x + 19+x = 97

2x + 19 = 97

2x = 97 - 19

2x = 78

x = 78/2

x = 39

Bobs typing speed = 39

Bill's typing speed 39 + 19 = 58

Hence, Bobs speed is 39 words per minute.

Ymorist [56]

Answer:

y = 0,5 x + (-3)

Step-by-step explanation:

We can see from the graph that when y = -3, the line crosses y axis, therefore

y = ? x + (-3)

We can also spot that when x = 6, y = 0

// now mark ? sign as a variable k and put the given x and y values into the previous expression

y = k * x - 3

0 = k * 6 - 3

k * 6 = 3

k = 3/6

k = 0,5
