Answer:

12. -11

13. 2

Step-by-step explanation:

12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction

For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.

From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.

Your new equation is -10-8+7 = -11

13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))

  • keep in mind there’s an addition between the two

Division and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17

Second multiply 5 x -3 = -15

Now you can combine the two answers using addition: 17 + (-15) = 2

Answer:

  • adult: $5
  • student: $15

Step-by-step explanation:

If we let 'a' represent the price of an adult ticket, and 's' represent the price of a student ticket, the two sales can be described by ...

  5a +4s = 85

  5a +2s = 55

Subtracting the second equation from the first gives ...

  (5a +4s) -(5a +2s) = (85) -(55)

  2s = 30 . . . . simplify

  s = 15 . . . . divide by 2

Substituting this into the second equation, we have ...

  5a +2(15) = 55

  5a = 25 . . . . subtract 30

  a = 5 . . . . . divide by 5

Each adult ticket sold for $5; each student ticket sold for $15.

I need help with this. Can u plz show ur steps

74-17= 57 because if you subtract 10 from 74, it would be 64, then you need to subtract 7 from 64, which gives you 57.

9+7=16 because 10+7 would be 17, but since 9 is one less than 10, you need to subtract one from 17, which gives you 16.

17+(-30)=(-13) because adding 17 to -30 only brings up -30 to -13, and -30<-13.

-41+24=-17. Same reason as question 3, only different numbers.

-36+(-7)=-43 because adding two negatives together is like subtracting two positives from each other.

14+64=78 because adding 10 to 64 is 74 and 74+4=78.

-53-42=-95 because when you subtract a positive from a negative, it decreases the number even more.

-17-(-62)=45 because -62 is less than -17 and it is being subtracted from -17 so the answer becomes positive.

Hope this helps :)
