Answers: Choice A and Choice E </h3>
Explanation:
The distributive property allows us to go from the original expression to choice A. We multiply the outer term 8 by each term inside the parenthesis.
In general, the distributive property is a(b+c) = ab+ac. Example: 2(3+4) = 2(3)+2(4) = 6+8 = 14.
After simplifying the expression in choice A, it leads directly to choice E. This is because 8(6x) = 48x and 8(9) = 72.
Side note: A common mistake students do is to multiply the outer term by only one of the terms inside the parenthesis, while forgetting about the other term inside. Choice B shows this mistake. It's possible your teacher put choice B in there as a trap/trick answer.
This requires 2 pints of oil.
Using a proportion to solve this, we have:
Cross multiplying, we have
1/2*10 = (2 1/2)*x
5 = (2 1/2)x
Divide both sides by 2 1/2:
5÷(2 1/2) = (2 1/2)x÷(2 1/2)
2 = x
Try using the equation v= pi(r)^2
If this is a good coin meaning that the head has as many chances as being flipped as a tail then you can expect 48.
There are only two options per flip and thus both sides have an even chance of getting flipped. So each would have half the number of flips to be flipped.
Hope that helped!
