One example of number line of rational numbers is shown below

To help with addition, for example, 0.1 + 0.3, you'd start from 0.1 on the number line and then hop on three lines to the right. You should end at 0.4 and that's the answer

To help with subtraction, you would have to 'hop back'.

What is the measure of an angle if it is 260 degrees less than six times its own complement?
poizon [28]

Answer:

40 degrees

Step-by-step explanation:

Complementary angles have a sum of 90.

y = 90 - x

The angle is 260 degrees less than six times its complement.

y = 6x - 260

90 - x = 6x - 260

350 - x = 6x

350 = 7x

50 = x

This is the measure of the complement.

y = 90 - x

y = 90 - 50

y = 40

This is the measure of the first angle.
