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.
-7+3/6+6=-4/12= -1/4
y+3= -1/4(x+6)
y+3= -1/4x-3/2
y=-1/4x-9/2
Answer:
2.5
Step-by-step explanation:
When a variable is next to a number (coefficient) it means you need to multiply. In this equation 6x are next to eachother.
Because we don't know what x is, we have to work backwards.
The opposite of multiplying is dividing, so here we can do...
15/6 and that equals 2.5
To check you replace x with 2.5 like so,
6(2.5)= 15 and it is true!
Hope this helps and have a great day!
Answer:
201.06 square inches.
Step-by-step explanation:
The equation to use to find the Area of a circle is given as
πr²
Where r = radius of the circle
In the question, we are given the radius of the circle = 8 inches
Area of the circle = π × 8²
= 201.06 square inches.
Step-by-step explanation:
x=y+9
substitute
3(y+9)+8y=-6
3y+27+8y= -6
13y = -6 -27
13y= -33
y = -33/13
x = -33/13 + 9
