Keisha ran 2.4 miles more than Jamal.

Keisha ran 8.5 miles, how many miles did Jamal run?


m = the number of miles Jamal ran


2.4 + m = 8.5

[Keisha ran 2.4 more miles than Jamal(m), she ran a total of 8.5 miles]


2.4 + m = 8.5   Subtract 2.4 on both sides

m = 6.1


Jamal ran 6.1 miles (Your answer is the 2nd option)

Emily has 8 coins in her purse totaling 50 cents. The only kinds of coins she has are nickels and dimes. How many nickels does E
miskamm [114]

Linear equation are the equation which has the power of the unknown variable is 1. The Emily have total 2 number of dimes coin and total 6 number of nickels coin.

<h3>Given information-</h3>

Emily has 8 coins in her purse totaling 50 cents

The only kinds of coins she has are nickels and dimes.

<h3>Nickel</h3>

A nickel is a coin which has the value equal to the 5 cents.

<h3>Dimes</h3>

A dimes is a coin which has the value equal to the 10 cents.

Suppose the number of nickel coin is <em>x </em>and the number of dimes coin is <em>y.</em>

As total coins are 8 . Thus,

x+y=8      

x=8-y                  ......equation 1

As the total value of the cents is 50 and nickel is equal to the 5 cents whereas the dimes is equal to the 10 cents. Thus,

5x+10y=50        

Put the value of the <em>x</em> from the equation 1 in the above equation.

\begin{aligned}5(8-y)+10y &=50\\40-5y+10y &=50\\5y &=50-40\\y&=\dfrac{10}{5} \\y&=2\end

Thus Emily have total 2 number of dimes coin.

Put this value of y in equation 1 we get,

x=8-2\\x=6

Thus  Emily have total 6 number of nickels coin.

Hence the Emily have total 2 number of dimes coin and total 6 number of nickels coin.
