It would be the distributive property. :)
So 280=1.4x so 280/1.4 is 200 .7*200 is 140 so $140
Answer: D. 60100
Step-by-step explanation:
The formula for determining the sum of n terms of an arithmetic sequence is expressed as
Sn = n/2[2a + (n - 1)d]
Where
n represents the number of terms in the arithmetic sequence.
d represents the common difference of the terms in the arithmetic sequence.
a represents the first term of the arithmetic sequence.
From the information given,
n = 200 terms
a = 2
d = 3
Therefore, the sum of the first 200 terms, S200 would be
S200 = 200/2[2 × 2 + (200 - 1)3]
S200 = 100[4 + 597)
S200 = 100 × 601 = 60100
4,000,000 would be your answer
Answer:
you didn't clarify what to help you with if you are solving for x or y or in standard form so here is what i came up with: (these are all different answers)
Step-by-step explanation:
X= y^2/2+3y+13/2
y= 
y= -
in standard form: -3
