So, let's put the test scores in fractions. We need them to have a common denominator, so let's use 10.
5/10=b 2/10=a 3/10= c or below
I added up 5/10 and 2/10 and subtracted that from 10/10 because it represents the rest of the test scores. We need to find how many students are 3/10.
We could multiply 3/10 by 30. Or we could divide 30 by 10, and multiply that by 3. Either way, we get 9.
So, 9 students scored a c or below on the test.
Answer:
12
Step-by-step explanation:
6(d+1)−2d=54
Here, we have to find the value of d
multiply (d+1) by 6
6×d + 6×1 - 2 d= 54
6d + 6 - 2d= 54
Now subtract 2 d from 6d
6d- 2d +6= 54
4 d+ 6=54
Now, by using transposition method,
+ 6 will be transferred from L.H.S to -6 to R.H.S
4 d = 54- 6
4d= 48
Now, divide 48 by 4
d= 48÷ 4
d= 12
Hence, the value of d is 12
Hence, the correct answer is 12
Answer:
First divide 3 on both sides to get x by itself, now you have x < -2.

Answer:
C: 124
Step-by-step explanation:
If you look at the angle it has to be over 90 degrees so therefore your only option is C: 124.
