From birth to 5yo = 91,200
from 5 to 18yo = 167,000
therefore from birth to 18yo will cost 91,200 + 167,000 which is 258,200
Since the question says per year and thats the total cost of 18 years ( from 0 years to 18), we divide it by 18.
258,200 ÷ 18 = 14,344
Answer a: 14,344
The rate of change in this pattern is 2:1 comparing the change in 'y' to the change in 'x'.. this means that if you go form 33 to 51 ( an increase of 18), then the the increase from 16 to ? will be 9. Therefore, ? = 16 + 9 or 25
? = 25
Seeing where the x and y diffreant on the line :)
Answer: x=13
explanation:
-2x+6=-20
subtract 6 from both sides
-2x=-26
divide -2 by both sides
two negatives equals a positive
x=13
Equivalent systems = same line = infinite solutions
