Answer:
a. √9
Step-by-step explanation:
a. √9 = 3
b.√15 = sqrt(5*3) cannot be simplified
c. √18 = sqrt(9) sqrt(2) = 3 sqrt(2) cannot be simplified farther
d. √20= sqrt(4) sqrt(5) = 2 sqrt(5) cannot be simplified farther
a is the only answer that is a rational number
Answer:
hold on what is the problem?
Step-by-step explanation:
also 113
Answer: 900 times
Step-by-step explanation:
1 kilometer = 1000 meters
1.8 kilometers = 1000 × 1.8
1.8 kilometers = 1800 meters
2 meters = 1 click
1800 meters = 1800 ÷ 2
1800 meters = 900 clicks
The wheel will click 900 times when Ty walks 1.8 kilometers.
Hope this helped!
You didn't really ask a question, so I'm assuming you want to know if there are any solutions to BOTH equations.
Use the first equation to substitute 4x - 1 for y in the second equation:
12x = 3(4x - 1)+7
12x = 12x - 3 + 7
12x = 12x +4
0 = 4
The last equation is FALSE, indicating the system of two equations has no solution.
Answer:
x > 5
