The _______ are all the counting numbers.
Bingel [31]
It cannot be be Integers because Integers include negative numbers (which are not counting numbers)

It cannot be real numbers because like integers, it includes negative numbers but also includes decimals which are not counting numbers

It cannot be absolute values because absolute values is the range of how far away a number is from 0 which obviously isn't counting

That leaves natural numbers which are counted in sequence which fits the definition needed

Answer: D. Natural Numbers

If tv =74 and wv = 4x + 1, solve for x
barxatty [35]

Answer: x equals 9

Step-by-step explanation: The figure in the question is a Rhombus and one of the properties of a rhombus states that “the diagonals bisect each other.”

This means line SU bisects line TV into two equal parts at point W. This also means that line WV is half of line TV. If line TV equals 74 and line WV equals 4x + 1, then we have the following;

(4x + 1) x 2 = 74

4x + 1 = 74/2

4x + 1 = 37

Subtract 1 from both sides of the equation

4x = 36

Divide both sides of the equation by 4

x = 9.

2.
Tanya [424]

Answer:

(A) 24 and 66

Step-by-step explanation

Complementary angles add up to 90 degrees

Supplementary angles add up to 180 degrees

(A) 24 + 60 = 90

These 2 angles sum to 90, so therefore they are complementary

(B) 56 + 124 = 180

These 2 angles sum to 180, so they are supplementary, not complementary

(C) 34 + 66 = 100; 34 + 56 = 90

While 34 and 56 sum to 90 degrees, 34 and 66 sum to 100, so this answer does not satisfy the question

(D) 56 + 124 = 180; 66 + 114 = 180

Both of these angle pairs are supplementary, so they do not satisfy the answer to the question
