First option because 3 x 10^9 is 3,000,000,000
Answer:
C) y is equal to 10.5x
Step-by-step explanation:
$31.50 is charged for <em>3 </em>hours so, for 1 hour we need to divide 31.50 by 3, which results in 10.50. So 1 hour of babysitting is $10.50
this is because x is equal to the number of hours they babysit. we do not know the actual so it is replaced with x
and y is equal to the sum of 10.5x because we multiply the number of hours worked, and the amount per hour.
Convert to hours, then days, then years
60 minutes per hour
1000000/60=50000/3=16666.7 hours
24 hours per day
16666.7/24=694.4 days
365 days per year
694.4/365=1.9
the average person lives at least 1.9 years
maybe, I guess
I have attached the correct answer. Brainliest will be much appreciated!
Hey there!!
Basic formula :
... a² - b² = ( a + b ) ( a - b )
Equation given :
... 81x² - 25
... ( 9x )² - ( 5 )²
... ( 9x + 5 ) ( 9x - 5 )
Hope it helps!!
