I need help on math. ASAP please I am stuck on this homework problem
Papessa [141]

Answer: white = $13, double = $14

<u>Step-by-step explanation:</u>

Let white chocolate chip dough = x

Let double chocolate chip dough = y

Mary:      3x + 2y = 67

Darryl:  <u> -(3x + 4y = 95)</u>

                     -2y = -28

                  <u> ÷-2   </u>  <u>÷-2  </u>

                        y = 14

3x + 2y = 67

3x + 2(14) = 67

3x + 28 = 67

<u>       -28 </u>  <u>-28</u>

3x         = 39  

<u>÷3        </u>   <u>÷3  </u>

 x         = 13

Solve the equation below:<br><br> ln x- ln 5= -1
Anastaziya [24]

Answer:

x = 5/e

Step-by-step explanation:

ln x- ln 5= -1

We know that ln a - ln b = ln (a/b)

ln x- ln 5= -1

ln(x/5) = -1

Raise each side to the power of e

e^ ln(x/5) = e^-1

We know that e^-1 = 1/e

x/5 = 1/e

Multiply each side by 5

x/5 *5 = 1/e * 5

x = 5/e
