Use distributive property to get rid of the parenthesis.....

9x - 3 + 6 - 2x = 0
combine like terms
7x + 3 = 0
move the 3 over by subtraction
7x = -3
divide by 7
x = -3/7

3×3 is 9/ 3×-1 is-3
2×3 is 6/ 2×-1 is-2
9x-3+6-2x=0

Then add common components
7x+3=0
-3 on each side
7x=-3
Divide by 7 on each side
X=-0.428

I will give brainliest <br> Find n. <br> 35n/35 = 700/35

adoni [48]

Answer:

Step-by-step explanation:

$\frac{35n}{35} =\frac{700}{35} \\$

multiply both sides by 35

$35*\frac{35n}{35} = 700 * 35\\35n = 700$

divide both sides by 35

$n = 20$

It is predicted that by 2050 there will be 10^10 people living on earth. approximatrly will be 10^12 trees. how many trees for e

Nastasia [14]

Interesting question. Does that mean near the end of humanity?

Solution 1:

10^10 = 1,000,000,000

10^12 = 100,000,000,000

100,000,000,000/1,000,000,000 = 100 trees per person

Solution 2:

10^12 / 10^10 --- 10^10 / 10^10

10^2/1 = 10^2 = 100 trees per person

Find the 9th term of the geometric sequence whose common ratio is 1/3 and whose first term is 2.

raketka [301]

Answer:

2/6561

Step-by-step explanation:

Geometric sequence formula : $a_n=a_1(r)^n^-^1$

where an = nth term, a1 = first term , r = common ratio and n = term position

given ratio : 1/3 , first term : 2 , given this we want to find the 9th term

to do so we simply plug in what we are given into the formula

recall formula : $a_n=a_1(r)^n^-^1$

define variables : a1 = 2 , r = 1/3 , n = 9

plug in values

a9 = 2(1/3)^(9-1)

subtract exponents

a9 = 2(1/3)^8

evaluate exponent

a9 = 2 (1/6561)

multiply 2 and 1/6561

a9 = 2/6561
