Answer:
The cost for all of the students is $391
Step-by-step explanation:
Since it costs $17 for each student and there are 23 students, you multiply 17 and 23 to get the cost for all students.
Answer: She isn't correct.
Step-by-step explanation: The BODMAS rule must be strictly followed and as such gives different answers to the two expressions.
(12-3)*2 basically gives:
9*2 (Dealing with the bracket first)
18.
While 12-(3*2) while dealing with the bracket first will give:
12-6; which would eventually give
6.
If you rewrite the equation to where y would be by itself it would be y=-5×+20.
The y intercept would be 20 and the x intercept would be 4
Simple....
you have:
-12+5k=15-4k
isolate the variable...
-12+5k=15-4k
+12 +12
5k=27-4k
5k=27-4k
+4k +4k
9k=27
k=3
Thus, your answer.
Exterior Angle Theorem: The measure of an exterior angle is equal to the sum of its 2 remote interior angles (That don't form a linear pair with it)
So its 25 + 90 = 115 (D)
ALSO it clearly cant be A because if you look at the angle, its greater than 90 degrees.
