What is the solution to this equation x -9=5

lukranit [14]

Answer:

x = 14

Step-by-step explanation:

x- 9 = 5

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Add 9 to both sides of the equation:

x - 9 (+9) = 5 (+9)

x = 5 + 9

x = 14

x = 14 is your answer.

Help me pls i really dk

I think its easier to work out part (c) first:-

People who liked anything except burger = 3/8 + 1/4 + 1/5 = 33/40

So the fraction who liked burgers = 7/40.

7/40 of the total liked burgers so total people surveyed = (40/7) * 126 = 720

ANswer to c is 720.

a) Number who liked chicken and laksa = (3/8 + 1/4) * 720 = 450 Answer

b) Number who liked pasta = 1/5 * 720 = 144

Therefore 144-126 = 18 more people liked pasta than burger , Answer.
