Answer:
the number is -1/3
Step-by-step explanation:
First thing, I am going to write out the equation for this:
-20x - 9 = 7x
Then, I will add 20x to both sides, so:
-9 = 27x
Then I will divide both sides by 27 to get the x alone
so:
x = -1/3
Answer:
It is cheaper to travel by car
Step-by-step explanation:
1200/30=40
This shows you need 40 gallons.
40x4=160
This shows it will cost Leonard $160 for the gas
2000+160=2160
This shows that if he chooses to travel by car he will pay $2160
$2500 is more then $2160 meaning it would be cheaper to travel by car
I believe it is x-4 but might be totally wrong
2, 11, 31, 59 and 97 are all prime numbers.
Answer: 17
if A+B= 5 and a-b=3, then a=4 and b=1. So, 4^(2)+1^(2)= 16+1=17
