Step-by-step explanation:
x is the angle.
complementary angles are adding up to 90°.
supplementary angles are adding up to 180°.
so,
90 - x = (180 - x) - 40 = 140 - x
0 = 50 ? no
there is something wrong here. this cannot work out, there is no solution. there cannot be a solution.
because due to the definitions, the supplementary measure of an angle must always be 90° larger than the complementary measure of the same angle. that is by default the difference in their definition.
so, if an angle is only 40° less than the supplementary angle, then it cannot be the complementary angle.
so, either there was a mistake in the question, or this is a trick question.
under the given circumstances, there is no solution possible.
There are many ways to solve number 5 as it is just an reduce/enlargement of equidistant fractions
The first method that came up to my mind is just dividing denominators.
For A) you can do 72 divided by 18 which would give you 4. Then you can divide the given numerator with the answer you got from dividing the denominators. This would be 8 divided by 4 which would give you two. This means that 2/18 is equal to 8/72. You can check by simplifying the fraction. Both 2/18 and 8/72 equal 9 when simplified, therefore correct.
You can use this method for b, either use a calculator because of the decimals or just remove the decimals and replace them later. Make sure when you use this method, you are always dividing the bigger number. So in B you would do 40.3 divided by 12.4
