7 0

Answer:

c = 3/2

Step-by-step explanation:

hello :

3(5-2x)=-4(cx+4)

-6x+15 = - 4 cx-16

-6x+4cx = -16-15    means 6x-4cx=-31

(6-4c ) x = 31

the equation have no solutions when : 6-4c = 0   (you have : 0x=31...false)

-4c=-6

c= -6/-4

c = 3/2

Mr Riley baked 1,692 chocolate cookies he sold them in boxes of 36 cookies each. How much money did he collect if he sold them a
Tatiana [17]

So first we need to find the total number of boxes that the cookies could fit in:

\frac{1,692}{36}=47

Now we know that 47 boxes were made from this amount of cookies.

If Mr. Riley sells each box for 8, then we need to multiply the number of boxes by 8:

47*8=376

So Mr. Riley will collect a total of 376 from selling all of his cookies.

It cost $520 to plant 4 acres of corn. How much would it cost to plant 3/5 acre of corn?
VLD [36.1K]
Importance should be given to all the informations that are already given in the question. based on those information's, the answer to the question can be easily determined.
The cost of planting 4 acres of corn = 520 dollars
Then
the cost of planting 1 acre of corn = (520/4) dollars
                                                       = 130 dollars
So
The cost of planting 3/5 acres of corn = (3/5) * 130 dollars
                                                             = 3 * 26 dollars
                                                             = 78 dollars
So the cost of planting 3/5 acre of corn is $78. I hope the procedure is clear enough for you to understand. You can always use this method in future for solving similar type of problems without requiring any help from outside.

Straight line = 180 °

5x + 78 = 180

5x = 180 - 78

5x = 102

x = 20.4

and y = 78 ° because y is an opposite angle of 78 °
