Answer:
10x + 20
Step-by-step explanation:
5x + 10 +5(x) + 5(2)
= 5x+10 +5x +10
= 10x +20
5.5% quarterly would give you slightly more.
Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A
-----> equation B
Substitute equation B in equation A
![3[15-y]+8y=55](https://tex.z-dn.net/?f=3%5B15-y%5D%2B8y%3D55)
Find the value of x
therefore
<u>the answer is</u>
the number of multiple choice question are 
the number of free response question are 
Answer:
20 times
Step-by-step explanation:
Given the following :
Probability of rolling a number less than 3 on a number cube:
Required outcome = (1, 2)
Total possible outcomes = (1, 2, 3, 4, 5, 6)
Required outcome / Total possible outcomes
= 2 /6
= 1/3
Hence, if number cube is rolled 60 times, number of times a number less than 3 is expected :
(Probability of obtaining a number less than 3 in one roll × number of rolls)
= (1 / 3) × 60
= 60 / 3
= 20 times
Answer: B
Step-by-step explanation: The number line has tally marks up to 3, so 3 has to be divided by something, meaning A and C do not work. There are 9 total tally marks circled, so the equation equals 9, leaving B as the only possible answer. Also, there are three tally marks per whole number, so each tally is 1/3, which is equal to 2/6, further proving it is B.
