you need to find a common denominator
Answer:
2
Step-by-step explanation:
Only reasonable answer, the other options are incorrect.
The sum of arithmetic series is given by:
Sn=n/2(a1+an)
where:
n=number of terms
a1=first term
an=nth term
but
n=18, an=275, Sn=4185
plugging the values in the formula we get:
4185=18/2(a1+275)
simplifying this we get:
4185=9(a1+275)
dividing through by 9 we get:
465=a1+275
thus
a1=465-275
a1=190
Answer: first number is 190
Answer:
Step-by-step explanation:
Given
- XY = 4x + 7 and YZ = 8x – 1
- XZ = ?
As per angle addition postulate
- XZ = XY + YZ
- XZ = 4x + 7 + 8x - 1
- XZ = 12x + 6
