Answer:
-5
Step-by-step explanation:
You have to subtract 3 and 7 which gives you -4 but since it's absolute value it becomes positive 4. The 9 stays as a positive 9. Then, you subtract 4 and 9 which gives you -5.
Ex1) a. supplementary (angle A + angle B gives 180) b. neither c. complementary (angle A + angle B gives 90)
Ex2) An angle of 180° (since it makes a straight line)
Supplementary angles are any angles that give 180 in sum, so for example 90° and 9°
Two different ones could be 150 and 30, for example
2 complementary angles are any angles that give 90 in sum, so for example 45 and 45 or 50 and 40
Since we know that a straight angle is 180 (like in the picture), and we are given (in that straight angle) an angle of 90° (the left) and 55° (CED) we only need to find BEC. Again, since a straight angle gives 180°, we just need to sum all of these and get 180°:
90 + 55 + BEC = 180
145 + BEC = 180
BEC = 180 - 145
BEC = 35°

Hi there!
Your answer is:
996 students were apart of this survey!
Step-by-step explanation:
3 out of 4 students means that 75% of students prefer the assemblies be held on Friday.
If 75% = 747 students then:
/75
1% = 9.96 students
×100
100% = 996 students
I hope this makes sense!
