I think it is 2/4 but I might be wrong
1. one hour and 25 minutes
2. 1,007.993
3.Yes it can. How? Simple. Can a triangle tessellate. Yes Inference in to a 3-D shape the same exact result.
4. 9:00 AM
5. 20 x 3 = 60
6. 4 x 8 = 32
7. 20 - 13 = 7
this is all i know i hope this helps :0)
Answer:
x = 4
Step-by-step explanation:
3x - 1 = 11
3x = 1 + 11
3x = 12
x = 12/3
x = 4
Thus, The value of x is 4

Answer:
a = 1
b = -1
Step-by-step explanation:
First, let's make equations out of those given f(x)'s
-4 = -3a + b
2 = 3a + b
We can use elimination method to get rid of the a real quick
-4 = b
2 = b
Add those together
-2 = 2b
Divide both sides by 2
-2/2 = 2b/2
b = -1
Plug in the new b in one of the original equations; I'm gonna use the bottom one
2 = 3a - 1
+ 1 + 1
3 = 3a
3/3 = 3a/3
a = 1
First, you add up the total number of students because we would base our percentage one this.
Total number of students = 1+4+5+10+20+10+5
Total number of students = 55
Now, let's count how many of them got a score of more than 70. For this, you would only count the students belonging to 70-under 80, 80-under 90 and 90-under 100.
Students who got more than 70 = 20+ 10 + 5 = 35
Therefore the percentage is equal to:
Percentage = 35/55 * 100 = 63.64%
