Step-by-step explanation:
9 = x/12
We will multiply 12 by 9
12 × 9 = x
108 = x
<span>If DE = 9, then ZA will be double of that .
</span><span>9+9=18
</span>So,
D) 18
Answer:
-1/6x + y = -5 or option D
Step-by-step explanation:
standard form is ax + by = c
The first term of this series (a+1) is 1 and the common ratio (r) is -3.
Thus, the explicit formula is a_n = 1*(-3)^(n-1).
Must check this! suppose we try to calculate the 3rd term. Then n = 3.
a_3 = 1*(-3)^(3-1) = (-3)^2 = 9. This is correct.
23x-13=2(x+2)
First you would distribute the 2 into the parenthesis
It will look like this after: 23x-13=2x+4
Then you would subtract 2x on both sides because u have to get the x's on one side
It will look like this after:21x-13=4
Then you would add 13 to both sides
It will look like this after: 21x=17
Then you would divide 21 on both sides
Your final product is 21/17
