Challenge A bag contains pennies, nickels, dimes, and quarters. There are 50 coins in all. Of the coins, 10% are pennies and 38% are dimes. There are 2 more nickels than pennies. How much
money does the bag contain?

5 pennies

7 nickels

19 dimes

$2.3

Step-by-step explanation:

first i like to find 1%

50/100=1%

50/100=0.5

then multiply to find %'s

0.5x10=pennies

0.5x10=5

0.5x38=dimes

0.5x38=19

since there are 2 more nickels than pennies there are 7 nickels since there are 5 pennies

then find each value and add

5x.01+7x.05+19x.10

0.05+0.35+1.9=$2.3

450 is the final answer! : )

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x
