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 $9$ bills 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.

How would I graph this and find the solution to this system. <br> y=-1/2x+4

Lesechka [4]

Answer: Easy, graph and solution

Step-by-step explanation: First what you want to do use the slope intercept form to find the slope and y intercept; -1/2 and y intercept (0,4). Any line can be graphed using 2 points. Select two x values, plug them into the equation to find the corresponding y values. Solution

1.) Step; x and y

Table:

0║4

8║0

All you had to do is divide 0=-x/2 +4= . (8) For the x intercept you get 8and for y you get 4 because you divided 0=-0/2+4

A man bought an article for #50,000, and sold it for #35,000. what is the percentage lost

Lyrx [107]

Answer:

30%

Step-by-step explanation:

Percentage loss is calculated as

$\frac{loss}{original}$ × 100%

loss = 50000 - 35000 = 15000, thus

percent loss = $\frac{15000}{50000}$ × 100% = 30%

PLZZZZ HELP ASAP PLZZZ

11111nata11111 [884]

Answer:

1. (5x - 2) + (2x - 2) + x = $180^{o}$

2. m<J = $113^{o}$

3. m<K = $44^{o}$

4. m<L = $23^{o}$

Step-by-step explanation:

Generally, the sum of angles in a triangle = $180^{o}$ .

So that;

m<J + m<K + m<L = $180^{o}$

(5x - 2) + (2x - 2) + x = $180^{o}$

5x + 2x + x -2 -2 = $180^{o}$

8x - 4 = $180^{o}$

8x = $180^{o}$ + 4

8x = 184

x = $\frac{184}{8}$

x = $23^{o}$

Thus,

m<J = (5x - 2)

= 5(23) - 2

= $113^{o}$

m<K = (2x -2)

= 2(23) - 2

= $44^{o}$

m<L = x

= $23^{o}$
