The sum of two numbers is 61. The larger number is 13 more than the smaller number. What are the numbers?
patriot [66]

Answer: 24 and 37

Step-by-step explanation:

Let the numbers be x and y . Also let us pick x as the larger number.

From the first statement :

x + y = 61 ............................ equation 1

From the second statement :

x = y + 13 ............................equation 2

Solving the resulting linear equations by substitution method, substitute x = y + 13 into equation 1, then

x + y = 61 becomes

y + 13 + y = 61

2y + 13 = 61

2y = 48

y = 24

Substitute y = 24 into equation 2 , then

x = y + 3 becomes

x = 24 + 13

x = 37

Therefore the numbers are 24 and 37

What is the sum of the first six terms of the geometric series? 2 – 6 18 – 54 ...
Law Incorporation [45]

The sum of the first six terms of the geometric series is -364.

A geometric series is a sequence of terms in a fixed common ratio.

Apparently, the expression "geometric progression" comes from the "geometric mean" (Euclidean term) of segments of lengths a and b: it is the length of the side c of a square whose area is equal to the area of ​​the rectangle. a and b. May

The series given is

2 – 6 + 18 – 54 + ...

The sum of n terms of a geometric series is given by

Sn=a1 * 1 - rn/1 - r

here the first term is 2

r = -6 /2 = -3

S = 2 (1-(-3)⁶)/(1-(-3))

S = -364

Therefore the sum of the First six terms of the geometric series is -364 .
