Answer:

14x+23 =65 x=3CDs

Step-by-step explanation:

So for any question where you need to write your own equation, it is first necessary that you determine what each number in the problem means in order to determine where they should go. James has $65 so the equation needs to be set equal to 65. The problem says he wants to buy a DVD for $23 so that would be a constant $23 spent regardsless of how many CDs he buys. We are trying to use the equation to determine how many CDs James can buy so the number of CDs is the x value at $14 each which would be 14x in the equation. so the equation would be the 14x for the unknown number of CDs, plus 23 for the constant DVD that James would buy set equal to the $65 he can use to buy everything.

To solve the equation, you must now isolate for x. To start, cancel out the +23 on the left side by subtracting 23 from both sides. This will leave 14x=42. You must then cancel the 14 by dividing both sides by 14 leaving your answer of x=3CDs.

I hope this helps.

James completed 18 math problems. This is 30% of the problems he has to do. How many total math problems must he complete to be
algol [13]

Answer:

60 = n

Step-by-step explanation:

This problem can be rewritten as:

18 is 30% of what?

% means "out of 100" and of means "multiply"

18 = 30/100 ⋅ n

100/30 ⋅ 18 = 100/30 ⋅30/100 ⋅ n

1800/30 = 100/30 ⋅ 30/100 ⋅ n (both the 30/100 and 100/30 are crossed out here)

60 = n

Ryan must do a total of 60 problems

Having done 18 problems already he has 42 remaining.

IM TOO LAZY TO DO WORK WILL MARK BRAINLIEST LOL
zaharov [31]

Answer:

18: x=98 y=38

19: x=20 y=50

Step-by-step explanation:

To figure out figure 18 you would first figure out x and a triangle equals 180 so 180- (36+46) which is 180-82= 98 and then there are vertical angles between the right and left side so x is equal to one of the angles on the right so 98+44= 142 and 180-142= 38

Then to figure out figure 19 you would first find y by adding 39 and 91 to get 130 and 180-130=50 and then 180-91 (for the angle in the bottom right for the left triangle) is 89 so 89+71=160 and 180-160 is 20.
