Answer:
Final answer is c. 15
Step-by-step explanation:
We need to find about what is the first term in the sequence for which d = -2 and a7 = 3
We will use nth term formula of arithmetic sequence.
we have been given a7 that means 7th term is 3
so plug n=7, d=-2 and a_n=3 into above formula
Hence final answer is c. 15
Answer:
1/6 of a pizza
Step-by-step explanation:
We need to take the amount of pizza and divide by the number of students
8/12 ÷ 4
Copy dot flip
8/12 * 1/4
8/48
Divide the top and bottom by 8
1/6
Each person will get 1/6 of a pizza
I do not know how many slices because it depends on how many slices each pizza is cut into.
Answer:
J=63
Step-by-step explanation:
3b+27=2b+57
subtract 27 from both sides
3b=2b+30
subtract 2b from both sides
b=30
K+J=180
substitute the value of b into K
2(30)+57+J=180
117+J=180
subtract 117 from both sides
J=63
