Answer:
The common difference is 5.
Step-by-step explanation:
The reason why is because to get from -4 to -9 is the same -9-(-4), the reason I did that because your finding the difference I put the bracket is so its easier to read, but it is the same answer. To find the difference an easy way would just be to look at it as a non-negative so you would do 9-4 which is 5, so the answer is 5.
8) The 4x should have been subtracted from the 8x instead of beating added
9) combine the like terms which are -18x and 5x
I believe it is D. hope this helps
The required amount Weiming has to pay is given by the limit of $150
more than the amount Joyce has to pay.
Response:
- The greatest amount Weiming has to pay is<u> $180</u>
<h3>Which method can be used to analyze the amount paid by Weiming and Joyce?</h3>
Amount Weiming agrees to pay ≥ 2 × Joyce agrees to pay
Amount Weiming agrees to pay ≤ 150 + Amount Joyce agrees to pay
Let <em>x</em> represent the amount Weiming agrees to pay, and let <em>y</em> represent
the amount Joyce agrees to pay, we have;
x + y = 210
x ≥ 2·y
x ≤ y + 150
When the amount Weiming is $150 more than Joyce, which is the
limiting amount for Weiming, we have;
x = y + 150
Which gives;
y + 150 + y = 210
2·y = 210 - 150 = 60
y = 60 ÷ 2 = 30
x = 30 + 150 = 180
Therefore;
- The greatest amount Weiming has to pay is, x = <u> $180</u>

Answer:
see explanation
Step-by-step explanation:
The geometric mean of 2 numbers a and b is 
The third term is the geometric mean of the first and fifth terms, that is
a₃ = 
= 31.5
The second term is the geometric mean of the first and third terms, that is
a₂ = 
= 10.5
The fourth term is the geometric mean of the third and fifth terms, that is
a₄ = 
= 94.5
Thus the sequence is
3.5, 10.5, 31.5, 94.5, 283.5
