Elden [556K]

Well, you already have the decay model, so just plug that in

$\bf A=96e^{-0.000121\cdot 17000}\implies A=96e^{-2.057}$

The solution is??? 3m-2/3-2m+1/4=2/12

zloy xaker [14]

3·m - 2/3 - 2·m + 1/4 = 2/12

m - 2/3 + 1/4 = 2/12

m = 2/12 - 3/12 + 8/12

m = 7/12

Connor has a collection of dimes and quarters with a total value of $6.30. The number of dimes is 14 more than the number of qua

Anarel [89]

Connor has 14 quarters and 28 dimes.

Step-by-step explanation:

Given,

Worth of coins = $6.30 = 6.30*100 = 630 cents

We know that,

1 quarter = 25 cents

1 dime = 10 cents

Let,

Quarter = x

Dime = y

According to given statement;

25x+10y=630 Eqn 1

The number of dimes is 14 more than the number of quarters

y = x+14 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$25x+10(x+14)=630\\25x+10x+140=630\\35x=630-140\\35x=490$

Dividing both sides by 35

$\frac{35x}{35}=\frac{490}{35}\\x=14$

Putting x=14 in Eqn 2

$y=14+14\\y=28$

Connor has 14 quarters and 28 dimes.
