Answer:
3
Step-by-step explanation:
If you substitute the values x = 0 and y = −5 into the second equation, you get a false statement: 2(−5) − 10 = 2(0). To solve this system, try rewriting the first equation as x = 2y − 8. Then substitute 2y − 8 in for x in the second equation, and solve for y. The correct answer is x = −2, y = 3.
Not what I really think it might be, but I hope it helped you!
Answer:
3/4 of the whole day(24 hours)
Step-by-step explanation:
1/3 of 24 hours equal to 8 hours. He slept for 8 hours. So his waking time equals 24-8=16
5/8 of his waking time (16 hours ) equal to 10 hours.
now total time spent in his house 10 + 8 = 18
in fraction 18/24 = 3/4
area of a circle = pi x r^2
using 3.14 for pi
radius = 36/2 =18
area = 3.14 x 18^2 = 1017.36 square inches
1 sq ft = 144"
1017.36/144 = 7.065 sq ft
7.065*3.50 = $24.73 to the nearest dollar = $25
