Hello :
the common ratio is r = -95-(-100)=5
the general terme is : un= u1+(n-1)r
un = -100 +(n-1)(5)
un =-100 +5n-5
un = 5n-105
The last term is : 100
un =100
5n-105 = 100
5n =205
n = 41 (Number of terms)
The last term is : u 41
<span>the sum is : S= (41/2)(-100+100)=0</span>
Answer:
9x -2
Step-by-step explanation:
(7x + 3) + (4x - 1) - (2x + 4)
Distribute the minus sign
(7x + 3) + (4x - 1) - 2x - 4
Combine like terms
7x+4x-2x +3 -1-4
9x -2

Answer:
x = 27
Step-by-step explanation:
I'm assuming the equation looks like this:

Here's how to solve for x:

(subtract 5 from both sides)

(Find the GCF of 3 and 9, which is 3. Multiply 2/3 by 3/3. You get 6/9)

(add like terms)

(multiply 9/5 to both sides, which is the same as dividing both sides by 5/9)
x = 27
