Answer:
-6
Step-by-step explanation:
1) distribute: 7x+28+6x-18=8x-24-2x+8
2)combine like-terms: 13x+10=6x-32
3)move the variable to one side: 7x+10=-32
4)subtract 10 from both sides: 7x=-42
5) divide each side by 7: x=-6
(X-2y)5=(3)5. 5x-10y=7 we - So 5x-10y-5x- 10y=-8
-20y=-8. y=8 over 20
Answer: 90% of the time.
Step-by-step explanation: This is because you can add the two different times and the standard time of 75 seconds, divide it all by 3 leaving you with 75.2 and that is 0.2 away from the original between those times all together. Take that 0.2 and subtract it from the 1.1 deviation and you’ll get 0.9 times that by 100 and you get it in a percentage; 90%.
