Answer:
-17z + 15a
Step-by-step explanation:
can't be simplied
answer:
-17z + 15a
Just answering because the thing says I have to
each class has 20 students
3 classes // 20 x3= 60
60 students + 11 teachers+13 parents = 84 people total
as you cant put half people in boats you round up to 90
meaning you would need 9 boats to have enough space for all of them xx
hope this helped x
2) Do both of the values of t have meaning for this application? Explain why
B) Break 48 into 12 groups of 4.
C) Break 12 into 4 groups of 48.
D) None of these.
Answer: B) Break 48 into 12 groups of 4.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given.
48÷12
This expression means dividing the number 48 by 12, or in other words, break 48 into 12 groups of 4.
So, if we solve :
48÷12= 4
In conclusion, the correct option is B)Break 48 into 12 groups of 4.
Feel free to ask for more if it´s necessary or if you did not understand something.

Answer:
(A) Linear pair postulate
Step-by-step explanation:
Given: AB intersects DE at point C.
To prove: ∠DCB≅∠ECA
Proof:
Statements Reasons
1. AB intersects DE at point C. given
2. ∠DCB and ∠BCE are a linear pair Definition of linear pair
3. ∠DCB is supplementary to ∠BCE Linear pair postulate
4. ∠BCE and ∠ECA are a linear pair Definition of linear pair
5. ∠BCE is supplementary to ∠ECA Linear pair postulate
Thus, from statement 2 and 5, we have
∠DCB+∠BCE=180° and ∠BCE+∠ECA=180°
⇒∠DCB+∠BCE=∠BCE+∠ECA
⇒∠DCB≅∠ECA
Hence proved
thus, option A is correct.
