Solve for A

ab - ac = 2
First, you need to factorize
a(b - c) = 2
a= 2/(b -c)

forsale [732]

① 15² = 4² + 2(32) x
225 = 16 + 64x
-64x = 16 - 225
-64x = -209
x = 209/64

② 105 = 45 + 5x
-5x = 45 - 105
-5x = -60
x = 60/5
x = 12

1.) Use the following information to solve the questions. Kay sold 200
Yakvenalex [24]

9514 1404 393

Answer:

  • 75 adult tickets
  • 125 child tickets

Step-by-step explanation:

Let 'a' represent the number of adult tickets sold. Then (200-a) is the number of child tickets sold, and the revenue is ...

  8a +5(200 -a) = 1225

  3a = 225 . . . . . . . . . . subtract 1000, simplify

  a = 75 . . . . . . . . . . . . .divide by 3

  200 -a = 125

75 adult ($8) and 125 child ($5) tickets were sold.

<em>Additional comment</em>

The question asked here is "how many tickets did Kay sell?" The second line of your problem statement tells you the answer: "Kay sold 200 tickets ...". We have assumed that you are interested in the breakdown of tickets sold, even though that is not the question that is asked here.

One set of markers cost x dollars. How much would set of makers and crayons cost together
inysia [295]

Answer:

x+y

Step-by-step explanation:

Let's pretend the value of the crayon's is 'y'. The value of the markers is 'x'. If we add them together, we get x+y. This is because we do not know the value of each variable.

Hope this helps! Have a nice day <3
