Answer:
B (dint take my work for it)
Answer:
13
Step-by-step explanation:
Opening the brackets, we have
5x – 5 = 20x –200
Collecting like terms, we have:
5x – 20x = –200 + 5
– 15x = –195
Dividing both sides by the coefficient of "x"
–15x/–15 = –195/–15
x = 13
Answer:
c.) 38
Step-by-step explanation:
means "summation of the all the elements starting from the 3rd element to the 6th element".
The 3rd element in the series is 14, and the 6th element is 5; we have to add these and all the elements between them together.
∴
= 14 + 11 + 8 + 5
= 38
