The complement of angle B is 90-x.

Now, 7 times the complement of angle B is 7*(90-x).

The supplement of angle B is 180-x.

Twice the supplement of angle B is 2*(180-x).

Here is the algebra:

7*(90-x)-2*(180-x)=220

630-7x-360+2x=220

-5x= 220+360-630

-5x=-50

x= -50/-5

x=10 degrees

Answer: 10 degrees.

By using a number line, arrange each of the each of the following in descending order (a) 4 29upon 33, -2.365,5.5,-3 upon 4 (b)

Sergeeva-Olga [200]

The arrangement of the numbers in descending order (largest to smallest) are as follows;

a). 5.5, 4, 29/33, -3/4, -2.365
b). 10, 5.855, 5/8, 1/2 -2π, -8

<h3>What is the arrangement of the numbers in descending order in each case?</h3>

It follows from convention that the positive numbers are larger than negative numbers and hence, should appear before negative numbers when the arrangement is in descending order.

Consequently, the numbers can be evaluated and arranged as in the answer above with positive numbers increasing rightwards and negative numbers decreasing leftward of 0 on the number line.
