Answer:
Arithmetic sequence
Step-by-step explanation:
A sequence is described as an arithmetic sequence when there is a common difference between the numbers
A sequence is a geometric sequence when there is a common ratio between the numbers
12,10,8
10-12= -2
8-10= -2
10/12= 0.83
8/10= 0.8
Hence the sequence is an arithmetic sequence with a common difference of -2
Answer:
4 cans of soup and 2 frozen dinners.
Step-by-step explanation:
Let the can of soup = x
Let frozen dinner s = y
Davis wants to the grocery store and purchased cans of soup and frozen dinners.
Each can of soup has 250 mg of sodium and each frozen dinner has 550 mg of sodium.
David Purchased twice as many cans of soup as frozen dinners and they all collectively contain 2100 mg of sodium.
x = 2y
Hence:
250x + 550y = 2100
250(2y) + 550y = 2100
500y + 550y = 2100
1050y = 2100
y = 2100/1050
y = 2
Since
x = 2y
x = 2 × 2
x = 4
Hence,
the can of soup = x = 4
Let frozen dinner s = y = 2
Davis bought 4 cans of soup and 2 frozen dinners.
Step-by-step explanation:
first you should do is that find the common difference which is 9
2x + 4 = 2x + 2
2x - 2x = 2 - 4
0 = -2 ......(when the variables drop out and ur left with an untrue statement, this means there are no solutions)
2x + 5 = 2x + 5
2x - 2x = 5 - 5
0 = 0.....(when the variables drop out and ur left with a true statement, this means there is infinite solutions)
so the two possible solutions when the variables drop out are : no solutions and infinite solutions
