You have dimes and quarters in your pocket. There are 12 coins that total $2.25. Write and solve a system of linear equations to

icang [17]

Answer:

Hence the System of equation are $\left \{ {{x+y=12} \atop {0.1x+0.25y=2.25}} \right.$

There are 5 dimes and 7 quarters in my pocket.

Step-by-step explanation:

Let Number of dimes be 'x'.

Also Number of quarters be 'y'.

Now Given:

Total Number of Coins = 12

So the equation can be framed as;

$x+y=12 \ \ \ \ equation \ 1$

Also Given:

Total Amount in pocket = $2.25

Now we know that 1 dime = $0.1

Also 1 quarter =$0.25

So the equation can be framed as;

$0.1x+0.25y = 2.25 \ \ \ \ equation \ 2$

Hence the System of equation are $\left \{ {{x+y=12} \atop {0.1x+0.25y=2.25}} \right.$

Now Solving the equation we get;

Now Multiplying equation 2 by 10 we get;

$10(0.1x+0.25y)=2.25\times10\\\\10\times0.1x+10\times0.25y=22.5\\\\x+2.5y=22.5 \ \ \ \ equation\ 3$

Now Subtracting equation 1 from equation 3 we get;

$(x+2.5y)-(x+y)=22.5-12\\\\x+2.5y-x-y =10.5\\\\1.5y =10.5\\\\y= \frac{10.5}{1.5}= 7$

Now Substituting the value of y in equation 1 we get;

$x+y=12\\\\x+7=12\\\\x=12-7 =5$

Hence there are 5 dimes and 7 quarters in my pocket.

What’s bigger cm or km

Komok [63]

Answer: km

Kilometers (km) are larger than centimeters (cm), so you expect there to be less than one km in a cm. Cm is 10 times smaller than a dm; a dm is 10 times smaller than a m, etc. Since you are going from a smaller unit to a larger unit, divide.

A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is

Scorpion4ik [409]

Answer:

26 ounces of 55% solution
104 ounces of 80% solution

Step-by-step explanation:

Let x represent the quantity of 80% solution. Then 130-x is the amount of 55% solution. The total amount of salt in the mix is ...

0.80x +0.55(130 -x) = 0.75·130

0.25x = 0.20·130 . . . . . . . subtract 0.55(130)

x = 0.20/0.25(130) = 104

130-x = 26

She should use 26 ounces of 55% solution and 104 ounces of 80% solution.
