Answer:

Step-by-step explanation:
Samantha's total earning per week are going to include the fix weekly wage of $350, plus whatever she gets from the tips. SInce what she gets from tips she noticed to be $12 per hour, if she works x hours during the week, the amount coming from tips only will be= $12*x
Therefore the total earning per week will add up to: $350 + $12*x
On the other hand, if we want to express her "average" hourly earnings, we need to divide the quantity above by the number of hours she works per week (we named such "x"): 
Therefore, the last expression that states that "Samantha's average hourly earnings is $22", can be written as: 
Answer:
if you decrease 10 kg by 10% you get 9 kg
So if 11 units on the map is 5m in real life, the scale is 11 units= 5m
But we need 100m.
We would need 20 groups of 5m to get 100m.
So we would need 20 groups of 11 units, which is 220 units.
So, on the scale drawing, the square would need to be 220 units by 220 units.
For the 3 days he ran a total of : 3 * 900 = 2700 meters.
1000 meters = 1 kilometers
2700 meters = 2700 / 1000 = 2.7 kilometers.
Between last week and this week, Bill ran a total of 6 kilometers.
How far he ran this week = 6 - 2.7 = 3.3 kilometers.
Option C.
Answer:
Subtract 4 and then add 6.
Step-by-step explanation:
8-4=4
4+6=10
10-4=6
6+6=12
12-4=8
8+6=14
The rule for this pattern can be subtracting 4, and then adding 6.
