Answer:

There are 5 five dollar bills and 4 ten dollar bills.

Step-by-step explanation:

Given:

Selling price of bicycle =\$65.

The friend gave x five dollar bills and y ten dollar bills.

Total number of bills =9.

To find: Number of five dollar bills and ten dollar bills the friend gave.

Solution:

The friend gave x five dollar bills and y ten dollar bills and the friend gave 9bills in all.

So, x+y=9.

\Rightarrow x=9-y   ...(i)

Selling price of bicycle =\$65.

So, 5x+10y=65...(ii)

Putting the value of x from equation (i) in equation (ii).

\Rightarrow 5(9-y)+10y=65

\Rightarrow 45-5y+10y=65

\Rightarrow 45+5y=65

\Rightarrow 5y=65-45

\Rightarrow 5y=20

\Rightarrow y=\frac{20}{5}

\Rightarrow y=4

Now, putting the value of y in equation (i).

\Rightarrow x=9-4

\Rightarrow x=5

Hence, there are 5 five dollar bills and 4 ten dollar bills.

Nick's dad wanted to measure the length of his backyard and asked Nick to do this with his footsteps. Since it was winter, they
Lerok [7]

Answer:

2244 cm

Step-by-step explanation:

The first first thing we must do is find the LCM of the following numbers

(51; 68) = 204.

This means that the first time they coincide is at 204.

Now, since his steps always coincide after 204

In Nick's case

Nick's 204 ÷ 51 = 4th step

and in the case of the father

204 ÷ 68 of his father = 3rd step.

Which means that in the 204 cm distance, there will be a total of 6 foot steps, except in the first 204 cm when your "initial" step is counted.

Replacing these values we have that the total distance will be:

67-1 (initial step) / (6 * 204) = 2244 cm
