(3x + 1/2 ) + ( 7x - 4 1/2 )
3x+7x + 1/2 - 4 1/2
10x -4

Answer:
20,000(x)^0.85 = 12,000
Step-by-step explanation:cd
if it "depreciates" over time, you take the value that it depreciates by and divide the full value of the car by that and get ^0.85, then, once you find the quotiont, you multiply that by the number of years it takes until you reach the goal. I have explained how to solve this problem, even gave the answer, but, I did not give the number of years, good luck! ;)
Answer: The approximate surface area of the larger pyramid is 159.31 ft².
Step-by-step explanation:
A pyramid is a solid,
And, When two solids are similar then the ratio of their surface area is the square of the scale factor of similarity.
Here, the scale factor of similarity

Thus, by the above property,

It is given that, the smaller pyramid has a surface area of 25.49 ft²,




If 10t = 9
t = 9/10 (as a fraction)
This is equivalent to 0.9
New answer is -0.9. step by step in the comments
