Answer:
The first option
Step-by-step explanation:
Answer:
If 2p + 6a = $14
and 3p + 9a = $21
then the following would also be true:
1p + 3a = $7
If p = pear and a = apple, how much would each cost? The unit prices can be determined by looking at the pattern. You can use multiplication to solve the problem.
For example, 1p + 3a*2 = $7
p = $1/each
a = $2/each or $6 total
See, pls, the suggested explanation:
3(5x-1)²=27 ⇔ 75x²-30x-24=0 ⇔ 25x²-10x-8=0 ⇒
Answer:
k = 4.
Step-by-step explanation:
An arithmetic sequence has a common difference.
So for this to be arithmetic:
k + 3 - (k - 1) = 3k - 1 - (k + 3)
k + 3 - k + 1 = 3k - 1 - k - 3
3 + 1 = 2k - 4
4 + 4 = 2k
k = 4.
The sequence is 3, 7, 11.
