In order to solve for this question, let's assign a couple variables.
The variable 't' will represent the number of two-point questions, and the variable 's' will represent the number of six point questions.
From the given, we can already form two equations:
t + s = 36
("An exam... contains 36 questions")
2t + 6s = 148
("An exam worth 148 points... Some questions are worth 2 points, and the others are worth 6 points")
Before we begin calculating anything, we can simplify the second equation we made, since all the numbers are divisible by 2:
2t + 6s = 148
t + 3s = 74
Now let's refer back to the first equation. We can subtract both sides by 's' (you could also subtract both sides by 't', but I personally think that this will make solving the equation less difficult):
t + s = 36
t = 36 - s
This effectively gives us a value for the variable 't'. We can assign this value back into our first equation:
t + 3s = 74
(36 - s) + 3s = 74
36 + 2s = 74
2s = 38
s = 19
Input 's' into our second equation to solve for 't':
t = 36 - s
t = 36 - 19
t = 17
There are 17 two-point questions and 19 six-point questions
- T.B.
-7= -(x-5)
Step 1: Distribute the secret -1 behind the parentheses so -1(x-5) is -1x+5
Step 2:-7= -1x+5 Subtract 5 from both sides --> -12=-1x
Step 3: Divide both sides by -1 so -12/-1 and -1x/-1
x=12
Answer:
In its broadest sense, no-fault insurance is any type of insurance contract under which the insured party is indemnified by their own insurance company for losses, regardless of the source of the cause of loss. In this sense, it is no different from first-party coverage.
