Y = x + 3 . . . (1)
4x + y = 18 . . . (2)
Putting (1) into (2) gives
4x + x + 3 = 18
5x = 18 - 3 = 15
x = 15/5 = 3
x = 3
y = x + 3 = 3 + 3 = 6
Solution = (3, 6)
the volume of cylinder is 3.14 r^2×h
Answer:
A
Step-by-step explanation:
A is an arithmetic sequence with first term -2 and common difference 5. Each new term is found by adding 5 to the previous term.
B is a geometric sequence with first term 1 and common ratio 1/2.
C is neither an arithmetic nor a geometric sequence.
D is neither. We might call it an "alternating sequence."
Answer:
B
Step-by-step explanation:
26% is close to 25%, which is equal to 1/4th.
You're adding to the number and removing from the percentage so it balances it out.
