Answer:
3 hours
Step-by-step explanation:
$12 = 2hours
Find how much Clare was paid for one hour
Total money earned ÷ number of hours = wage per hour
12 ÷ 2 = $6 per hour
set up equation
6x = 18
This equation says 6 dollars an hour × number of hours = $18
To solve for this equation, divide both sides by 6 (this isolates the variable)
6x ÷ 6 = 18 ÷ 6
1x = 3
x = 3
Answer:
6 cm
Step-by-step explanation:
1 cm : 9 meters --> 1cm/9m
? cm : 54 meters --> ?cm/54m
F ( x ) = - x² + 5 x + 4
between x = 3 and x = 5:
f ( 3 ) = - 3² + 5 · 3 + 4 = - 9 + 15 + 4 = 10
f ( 5 ) = - 5² + 5 · 5 + 4 = - 25 + 25 + 4 = 4
Average rate of change:
( 4 - 10 ) / ( 5 - 3 ) = - 6 : 2 = - 3 feet / sec
Answer:
B
Step-by-step explanation:
The answer is not A or D because they show a linear association
The answer is also not c because they show no correlation at all
The answer is B because it has a curve

$0.30
Here's why:
3.60 30
--------- = -----
12 1
3.60 / 12 = .3
12 / 12 = 1
