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

Two trains leave towns 976km apart at the same time and travel toward each other. one train travels 22 /kmh slower than the othe

PilotLPTM [1.2K]

Let s be the slow train, and s+22 be the faster one. Then:
976/s+s+22=4
976=8s+88
8s=888
s=111 kph as the slower train
s+22=133 kph as the faster train
