Method 1 :
(152+138+160)÷3 = 150
(152+138+160+198)÷4 = 162
Then his average score will increase
Method 2 :
Since 198 > 150 then the average will increase automatically.
Your choices A and C are the same
but the decimal of 1/11 is 0.090909
so your answer would be 2.09
-2/3 - 5/6
We need common denominators so, since 3 can go into 6, we only need to multiply the first fraction by 2.
= -2 x 2 / 3x2 - 5/6
= -4 / 6 - 5/6
We only subtract the numbers that are in the numerators,
= -4-5 / 6
= -9/6
Both nine and six are divisible by 3, so to put into lowest terms...
=-9÷3 / 6÷3
= -3/2 <--- Final Answer

Answer:
the hourly rates are $8 and $10 respectively
Step-by-step explanation:
Given that
The generator rents for 6 hours and the total cost is $48
And, for another job The generator rents for 4 hours and the total cost is $40
We need to find out the hourly rates
For the first one
= $48 ÷ 6 hours
= $8
For the second one
= $40 ÷ 4 hours
= $10
Hence, the hourly rates are $8 and $10 respectively
