Answer:
18 logs.
Step-by-step explanation:
Since a stove burns 4 logs per 2 hours, then the stove will burn 2 logs in one hour. There fore in 9 hours the stove will burn 2*9 which is 18 logs.
4:2= 2 logs per hour
2*9=18 logs per 9 hours.
9x-7=-7
9x=o
x=0
so the answer....is 0
Answer:
The answer is $350
Step-by-step explanation:
00 = 8 hours
28/8 = 3.5
3.5(100) = 350
The worker would earn $350 in 28 hours
<span>1/2x+3y/4=5 => (1/2)x + (3/4)y = 5
1/5x+3y/2=2 => (1/5)x + (3/2)y = 2
Eliminate the fractional coefficients: Mult. the first equation by 4 and mult. the second equation by 10:
2x + 15y = 20
</span><span>Multiply the 1st equation by -1:
-</span>2x - 3y = -20
2x + 15y = 20
-------------------
12y = 0, so y = 0. Then the first equation becomes 2x + 3(0) = 20, or
x=10.
Solution is (10,0).
Answer:
chord
Step-by-step explanation:
a chord is a line drawn from one part of a circle's circumference to another without passing through the centre.
If the line passed through the centre then it would be a diameter
