The Jurassic Zoo charges $8 for each adult

Mathematics
1 answer:
eimsori [14]3 years ago
6 0

Answer:

21 adults and 139 children

Step-by-step explanation:

x=adult (8$)

y=child (5$)

8x + 5y =863

x+y=160

-x       -x (subtract x on both sides)

y= -x + 160

plug that in for y on the other equation

8x + 5(-x + 160) =863

distribute 5 to both

8x + -5x + 800 = 863

combine both x values

3x + 800 = 863

     -800     -800 (subtract on both sides)

3x = 63

divide by 3 on both sides

x = 21 adults

now plug x in one of the equations

21 + y = 160

-21         -21

y=139 children

16h - 9 = -13 - 6h - 18<br><br> h=
densk [106]

Answer:

h = -1

Step-by-step explanation:

Solve for h:

16 h - 9 = -6 h - 31

Add 6 h to both sides:

16 h + 6 h - 9 = (6 h - 6 h) - 31

6 h - 6 h = 0:

16 h + 6 h - 9 = -31

16 h + 6 h = 22 h:

22 h - 9 = -31

Add 9 to both sides:

22 h + (9 - 9) = 9 - 31

9 - 9 = 0:

22 h = 9 - 31

9 - 31 = -22:

22 h = -22

Divide both sides of 22 h = -22 by 22:

(22 h)/22 = (-22)/22

22/22 = 1:

h = (-22)/22

The gcd of -22 and 22 is 22, so (-22)/22 = (22 (-1))/(22×1) = 22/22×-1 = -1:

Answer:  h = -1
