Answer:
B. 1 and 3
Step-by-step explanation:
Answer:
the common difference is 5.4 and yes, this is an arithmetic sequence
Step-by-step explanation:
Each new term is derived by adding 5.4 to the previous term:
2.1 + 5.4 = 7.5,
7.5 + 5.4 = 12.9,
and so on,
so the common difference is 5.4 and yes, this is an arithmetic sequence.
Your breaking the problem down.
8 x (40 + 7)
You notice how in the second part of the equation, the (8 x 7) the 40 is not there?
Your answer will be 8 x (40 + 7) = (8 x 40) + (8 x 7)
3/4x+3-2x=-1/4x+1/2x+5
3x+12-8x=-x+2x+20
-5x+12=x+20
-5x-x=20-12
-6x=8
-6x/-6=8/-6
X=8/-6
X=-4/3
For 23# the answer is $5.96 because you have to divide 17.84 divided by 3.
For 24# the answer is $18.50 because you multiply 0.36 and 50.
