We are given with the sequence -20, -16, -12, -8. From this sequence, we can see that the arithmetic difference is +4, from -(-20 + 16). hence following the arithmetic formula of an = a1 + d *(n-1). Substituting, an = -20 + 4 *(n-1) where n is an integer
It would be -2.449489743 or 2 and 11 25th in fraction
Answer:
The number is 27
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
The quotient of 9 and a number added to 30 is 33
30 + (n / 9) = 33
<u>Step 2: Subtract both sides by 30</u>
30 + (n/9) - 30 = 33 - 30
n/9 = 3
<u>Step 3: Multiply both sides by 9</u>
n/9 * 9 = 3 * 9
<em>n = 27</em>

Answer: The number is 27
If you substitute the -8 in for y you will get -72
You can then add the 72 to the other side and get -8x=64
Dividing by -8 to both sides to get x alone will give you x
X=-8
Every step is true hey why
