Find the number of miles driven by subtracting the odometer readings:
74545 - 74233 = 312 miles driven.
Divide miles driven by gallons of gas used:
312 / 9 = 34.66 = 35 miles per gallon.
Answer:x=18
Step-by-step explanation:2x-9=x+9
Answer:
Step-by-step explanation:
y = log (tan 2x)
Applying chain rule:
Now since 
∴ 
∴
The given situation above is an example of a geometric sequence with first term equal to three and the common ratio equal to 3. For the second day, Raul used 9 bags of cement. He used 27 bags on the third and 81 on the fourth. To answer the question, add the number of bags from second to fourth day. The answer is equal to 117 bags of cement.
The first number would be represented by x, the second as
x+2 and the third as
x+4. Together they equal 117, so x+x+2+x+4= 117. You can sinplify that to equal 3x+6=117. You then solve for x (subtract the 6 from both sides to get 3x=111, and then divide both sides by 3 and you get x=37). The three numbers would be 37,39, and 41. The smallest is 37.
