Please help quick Solve for x.​
Kamila [148]

Answer:

x = 3.75

Step-by-step explanation:

So, lets start with what we know.

Line = 180 degrees

Triangle = 180 degrees, a + b + c = 180

So, we can form the equations,

17x - 1 + <CDB = 180

-17x + 1                -17x + 1

             <CDB = 181 - 17x

and

84 +7x + 5 + <CDB = 180

89 + 7x      + <CDB = 180

-89                              -89 + 7x

                     <CDB = 91 + 7x

Here, we are given 2 values of <CDB, but they must be the same, so let's substitute them into each other

181 - 17x = 91 + 7x

-91 +17x   -91  +17x

90         =        24x

90 / 24  =        24x / 24

3.75       =           x

x            =           3.75

There, you have it, x is 3.75

John Walters is comparing the cost of credit to the cash price of an item. If John makes a down payment of $160 and pays $35 a m
GREYUIT [131]

Answer:

The amount is $275 more that the cash price of $725.

Step-by-step explanation:

It is given that John makes a down payment of $160 and pays $35 a month for 24 months.

Down payment = $160

Total amount of installments = $35 × 24 = $840

Total amount of product = Down payment + Total amount of installments

Total amount of product = $160 + $840 = $1000

Cash price = $725

Difference between credit and cash price is

Difference = $1000 - $725 = $275

Therefore the amount is $275 more that the cash price of $725.

A new homeowner buys 120 square feet of carpet for a room in her new house. If the room is square, what is the length of each si
Marina CMI [18]
As it is emphasized above, the area (A) of a square is the square of its sides (l),
                               A = l²
The area of the square should be 120 ft². Substituting this to the equation,
                             120 ft² = l²
Solving will give us an answer of l being approximately equal to 10.95 ft.
