Answer:
r = -39
Step-by-step explanation:
So we are trying to solve the equation for r.
-6(2r + 8) = -10(r - 3)
Divide both sides by -2. (This will make distributing much easier.)
3(2r + 8) = 5(r - 3)
Distribute the 3 on the left side and the 5 on the right side,
6r + 24 = 5r - 15
Subtract 24 from both sides.
6r = 5r - 39
Subtract 5r from both sides.
r = -39
So now we have solve the equation.
I hope you find my answer and explanation to be helpful. Happy studying. :)
Well the only right triangle with two similar sides is a special triangle called a 45 45 90. After the degrees of its shape
_
two sides are x and the other is x/2 _
so in this case the other angle would be 20/2 [20 root (2), its hard to draw roots on this site so I thought I would clarify that was what I was drawing]
Hope this helps, good luck.
Subtract 2.1 from both sides:
Add 1.4y to both sides:
Of course, we can rewrite this as
Divide both sides by 1.4
The formula for volume is Length x Width x Height.
So when you apply this formula to these questions the answers should be:
#7. 3x4x2 = 24
#8. 2x4x1 = 8
#9. 3x4x2 = 24
#10. 4x3x1 = 12
I hope this helps!
We know that 1 out of 8 rabbits are gray. And there is 2 gray rabbits.
You have to be proportionate:
there will be 16 rabbits total, because we keep the proportion of 1 out of 8
