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:
4.76
Step-by-step explanation:
constant of proportionality=slope
slope=m
y=mx+b
m=4.76
Answer:
a) yes b) no c) no
Step-by-step explanation:
In order to know this, remember something: to do the division between a number and a rational number like this and with zero to the left, the best way to solve them is converting these number to a natural number.
To do that, you only need to multiply the number by 10, 100, 1000, depending of how many decimals it have.
In case a) 0.05 has two decimals, therefore we multiply by 100:
0.05 * 100 = 5
However, when you do that, you have to do the same thing with the number in the dividend, in this case, 1.4:
1.4 * 100 = 140
So we can conclude that 1.4 you have to add a zero to do the division.
Case b) and c) do not apply, in both cases we multiply by 10 and we get this:
25.2 and 6,
26.1 and 3.
Answer:this is the answer of the question like at it
8 sides
the exterior angle = 180° - 135° = 45° ( exterior/ interior are supplementary )
the sum of the exterior angles of a polygon = 360°
number of sides = 
= 8
