Answer:
The first term of the sequence is a = 4
The sum of the first 13 terms is -480
Step-by-step explanation:
Given that:
The third term is: a + 2d = - 8 --- (1)
-230 = 10a + 45d
10a + 45d = -230 ----(2)
From (1) and (2)
a + 2d = - 8
10a + 45d = -230
From (1), let a = -8 - 2d
Replace, the value of a in (1) to equation (2)
10(-8 -2d) + 45d = -230
-80 -20d +45d =-230
25d = -230 + 80
25d = -150
d = -150/25
d = -6
From equation (1);
a + 2(-6) = -8
a -12 = -8
a = -8 + 12
a = 4
Thus,the first term of the sequence a = 4
= -480
Well, 40% is equal to 4/10. So we need to find what value of x will make x/35=4/10
To do this, we need to make the denominators equal. If we multiply 4/10 by 3.5/3.5 (which is another way of saying 1), we get 14/35 because 4*3.5 is 14 and 10*3.5 is 35
if x/35=14/35, then x=14!
We can check our work by dividing 14/35 in a calculator, and we get .4, or 40%.
Hope that helped!
