slavikrds [6]4 years ago

Answer:  There is one solution to the given equation.

Step-by-step explanation:  We are given to find the number of solutions to the following equation :

12x+6=5x~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

Since the given equation is linear in one variable x, so it will have only one solution.

The solution of equation (i) is given by

12x+6=5x\\\\\Rightarrow 12x-5x=-6\\\\\Rightarrow 7x=-6\\\\\Rightarrow x=-\dfrac{6}{7}.

Thus, there is one solution to the given equation.

You've baked 26 cookies, which is two-thirds of all the cookies you planned to bake. How many cookies did you plan to make?
hodyreva [135]

Answer,

<em>(26/2) * 3</em>

<em>= 39</em>

Explanation,

<u><em>26 cookies is only 2/3 of 3/3. So, we divide 26 by 2 to see how many cookies are in 1/3. We then can find out that when you make 1/3 of the cookies there are 13. Since that is only 1/3 and we want to find out 3/3. We multiply 13 by 3 and get 39 which is all the cookies she planned to make.</em></u>

The opening balance of one of Jennies 30-day billing cycles for her credit card was $1220, and it remained that amount for the f
natima [27]

Answer:

1) 2.71%

2) $38.32

Step-by-step explanation:

Opening balance = $1220

Balance after 10 days (after expense) = $1690

Balance after 10 days(after payment) = $1340

APR = 33%

1) Periodic interest rate = APR × \frac{No. of days in a billing cycle}{365}

                                  =  33%× 30/365

                                  = 2.71%

2) Interest charged for first 10 days = \frac{1220*2.71*\frac{10}{30} }{100}

                                                              = $11.02

Interst charged for the next 10 days = \frac{1690*2.71*\frac{10}{30} }{100}

                                                            = $15.2

Interest charged for the next 10 days = \frac{1340*2.71*\frac{10}{30} }{100}

                                                           = $12.10

Total interest for 30 days = 11.02+15.2+12.10

                                          = $38.32

The sum of two numbers is 66. two times the smaller number is 15 more then th larger number what are the numbers
Delicious77 [7]

Let x = big number

Let y = small number

x + y = 66...Equation A

2y = x + 15...Equation B

We have two equations in two unknowns.

x + x + 15 = 66

2x = 66 - 15

2x = 54

x = 54/2

x = 27

Plug x = 27 into EITHER equation above to find y.

I will use Equation A.

x + y = 66

27 + y = 66

y = 66 - 27

y = 39

The two numbers are 27 and 39.
