A wood stove burns 4 same sized logs in 2 hours how many logs does the stove burn in 8 hours
insens350 [35]
By using the information you have, you can use make a proportion to solve this. You burn 4 logs in 2 hours or 4/2. You are comparing this to your unknown number, x, over 8 hours. So it looks like this 4/2 = x/8. You read it as four logs in two hours is x logs in eight hours. To solve you cross multiply. You do 2 times x and 4 times eight. That would be 2x= 32. Your goal is getting x alone, so divide each side by 2. Your answer is x= 16 logs in eight hours. You can solve this different and maybe easier ways but this is the best way if you want to get used to going this in algebra. Hope that helps! :)

Select all the expressions that are equivalent to -36x+54y−90.
CaHeK987 [17]

Answer:

b) -18(2x -3y + 5)

d) 18(-2x + 3y - 5)

e) -2(18x - 27y + 45)

Step-by-step explanation:

a) -9( 4x - 6y - 10) = -36x + 54y + 90 not equal

b) -18(2x - 3y + 5) = -36x + 54y - 90 equal

c) -6(6x + 9y - 15) = -36x - 54y + 90 not equal

d) 18(-2x + 3y - 5) = -36x + 54y - 90 equal

e) -2(18x - 27y + 45) = -36x + 54y - 90 equal

f) 2(-18x + 54y - 90) = -36x + 108y - 180 not equal

X+7y=24 and x-9y=-24 doing elimination
nirvana33 [79]
The easy thing to do is eliminate x by subtraction 
 
   x + 7y = 24
- x - 9y = -24
-------------------
      16y = 48

now solve for y and then substitute the value into either original equation to find x

which statement is not a step used when constructing an inscribed equilateral triangle. A keep your compass at the with equal to
djyliett [7]

Answer: Connect the two circles together using the compass.

Steps to inscribe an equilateral triangle into a circle:

1. You are given a circle with the center marked.

2. Draw a radius of the circle using your straightedge.

3. Keep your compass open to the width of the radius and place it on the point where the radius and circle intersect.

4. Swing an arc the length of the radius that intersects the circle to the left of the radius originally drawn.

5. Keeping your compass at the same width, place it on the new intersection point you created in the previous step.

6. Continue this process until six points of intersection exist on the circle.

7. Connect together the first, third, and fifth intersection points.
