Step-by-step explanation:

Hi!

I didn't know if by the number 17) if it was IN the equation or if it was just counted as like you did 17 problems so i included both in the answer

The first answer is without the 17 and the second includes the 17

Hope this helps! Have a wonderful day! (Pls consider making me brainliest literally no one does it anymore XD)

If 30% of John's photographs were perfect, but 210 photographs were not perfect, then how many photographs were there in all?
anyanavicka [17]
If 30% were perfect, 70% were not perfect.  So we know that 70% of the total number of photographs is 210.

p(70/100)=210  multiply both sides by 100

70p=21000  divide both sides by 70

p=300

So there are 300 photographs in all.

I have 3 questions for math
Airida [17]

Answer:

  1. no question content
  2. (x, y) = (1/2, 4)
  3. (x, y) = (2, 10)

Step-by-step explanation:

1. No link, no question

__

2. Divide the first equation by 2 and substitute for y using the expression in the second equation.

  2x +(4x+2) = 5

  6x = 3 . . . . . . . . . subtract 2

  x = 3/6 = 1/2 . . . . divide by2

  y = 4(1/2) +2 = 4 . . . . substitute into the equation for y

The solution is (x, y) = (1/2, 4).

__

3. The solution using a graphing calculator is (x, y) = (2, 10). (see attached)
