1) D
(2/9) x=24
2) C
6x4=24
24=w
W=1/4(6)
3) A
67=9n
67=9n-2
9n-2=67
4) D
C+2x+x-3=56
4x=59
X=14.75
Katie payed 14.75
5) 91
Explanation: divide 18 by two and you get 9. When you add six and seven you carry on so those are your numbers. After you add you get your consecutive numbers, 91 and 92. 91 is the smallest so that is your answer
6)-18
Explanation: c+c+2=-34
2c+2-34
2x=-36
X=-18
18 is your answer
7) 17
Explanation: divide 22 is half. This is 11. 11+6=17. 17 is your answer
8)D
9)A
11-3 =x
However that isn’t an option so I would suggest to choose 3
10)D
4(17-n)=64
The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058
The given geometric sequence is:
4, -12, 36, -144
The first term, a = 4
The common ratio,

Since we are looking for the sum of the first 10 terms
The number of terms, n = 10
The sum of the first n terms of a geometric sequence is given as:

The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058

If you would like to know which pair of measurements is not equivalent, you can calculate this using the following steps:
1 yard = 3 feet
1 foot = 12 inches
1 mile = 5280 feet
8 yards = 8 * 3 feet = 24 feet
2 feet = 2 * 12 inches = 24 inches
10 feet = 10 * 12 inches = 120 inches
3 miles = 3 * 5280 feet = 15,840 feet
Not equivalent: <span>3 miles, 15,480 feet.</span>
I believe the answer is n=1.8
Hope this helped.<span />
