Step-by-step explanation:

1.) Begin by converting 2 yards into feet.

There are 6 feet in two yards, and 3 feet in one.

2.) Now that we have converted that, we can compare each length better.

3.) Take 6 feet and divide it by 10.80. You will get 0.55, or 55 cents.

4.) Now, take 12 feet and divide it by 24.60. You will get 0.48, or 48 cents.

5.) When you divide these numbers, you are seeing how many cents per foot of twine.

6.) Now, compare .55 and .48, or subtract the two. That will be 7 cents, or 0.07.

The difference is 7 cents, and 12 feet of twine for $24.60 is the better deal, as it costs less for more.

Answer:

$The\ brother's\ present\ age= 4\ years\\The\ sister's\ present\ age=8\ years$

Step-by-step explanation:

$Let\ the\ brother's\ present\ age\ be\ x\\Hence\ we\ are\ given,\\His\ sister's\ present\ age=(2x)\\Now,\\The\ brother's\ age\ before\ two\ years=(x-2)\\The\ sister's\ age\ before\ two\ years=3(x-2)\\Also,\\His\ sisters\ age\ before\ two\ years=2x-2\\Hence,\\3(x-2)=2x-2\\3x-6=2x-2\\3x-2x=6-2\\x=4\\Hence,\\The\ brother's\ present\ age= 4\ years\\The\ sister's\ present\ age=2x=2*4=8\ years$

Which of the following is an example of a valid use of the multiplication property of equality? A. to isolate s in the equation

marusya05 [52]

Answer:

D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1.

Step-by-step explanation:

We have a set of an example of equations; we need to study the use of multiplication property of equality.

A. to isolate s in the equation s – 4 = –12, divide both sides of the equation by.In this sentence, to isolate s we do not need multiplication only addition and subtraction.

B. to isolate s in the equation s – 4 = –12, multiply both sides of the equation by. In this sentence, to isolate s we do not need multiplication only addition and subtraction.

C. to isolate s in the equation –4s = –12, divide both sides of the equation by -4. This sentence is correct, and it uses division. However, we are studying multiplication property not division.

D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1. Firstly, it is a good idea to change both negative signs to positive by multiplying by -1 to isolate s.

Finally, we can conclude that a valid use of the multiplication property of equality is D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1.
