Find the sum of the first 36 terms of the following series, to the nearest integer.<br> 2, 5,8,...
Ivenika [448]

Answer:

Step-by-step explanation:

Comment.

You need to use the addition formula when the last term is not given. Mind you, you could find it, but it is just as easy to get the answer without it.

Givens

a1 = 2

d = 3

n = 36

Formula

Sum = n(a1 + (n - 1)* d)/2

Solution

Sum  =  36(2 + (36 - 1)*3 )/2                Combine the brackets

Sum = 36 (2 + 35*3 )/2

Sum = 36(2 + 105) /2                          Combine the brackets

Sum = 36 * 107/2                                    

Sum = 3852 /2

Sum = 1926

Answer

1926

Solve: –3x – 24 ≤ –36 what is x equal to?
Kay [80]

Answer:

X <= 4

Step-by-step explanation:

-3x - 24<= -36

Make -3x the subject, by carrying -24 to the other side

Note: Moving -24 to the other side changes to + 24

-3x <= -36 + 24

-3x <= - 12

Minus cancels minus

3x <= 12

Divide both sides by 3,to get the value of x

3x/3 <= 12/3

x <= 12/3

x <= 4

Therefore, x equals to 4
