Answer:

see below

Step-by-step explanation:

Which of the equations from part A represent adding two rational numbers?

Equations A, C, E

What hypothesis can you make about the sum of two rational numbers?

The sum of two rationals will always be rational

Will the addition result in a rational or an irrational number?

Our hypothesis is that the result is always rational. This can be justified by the fact that the sum of two rationals a/b + c/d, where a, b, c, d are integers and bd≠0, is (ad+bc)/(bd), a rational, based on closure of integers for multiplication and addition.

Which equations represent the sum of a rational and an irrational number?

Equations B, F

What hypothesis can you make about the sum of an irrational and a rational number?

The sum of a rational and irrational number is always irrational.

Alexandra [31]

Answer: -b - 9

Step-by-step explanation:

First, since the a cancel eachother out we are left with (4-b) + (-6-7)

Second, you want to add the -6 and -7 to get -13, so (4-b) - 13

Finally, add the 4 to the negative 13 to get (-b - 9)

Hope this helps.

What is the correct answer in the photo A. B. C. or .D please explain why

balu736 [363]

Answer:

I think its D)

Step-by-step explanation:

7x−3y+2=0

Add -7x to both sides.

7x−3y+2+−7x=0+−7x

−3y+2=−7x

Add -2 to both sides.

−3y+2+−2=−7x+−2

−3y=−7x−2

Divide both sides by -3.

−3y /−3 = −7x−2 /−3

which equals d)

Please help I don’t want to give up it’s getting hard

Svetradugi [14.3K]

Answer:

144 goes with 12, 36 goes with 6, 9 goes with 3, and 121 goes with 11.

Step-by-step explanation:

The second number stated in each phrase is time itself to create the first number. For example, 144. If we take the second number in the number phrase (12) and time it by itself (12 * 12) it equals 144. This applies to each number phrase.
