It would be: -2/3 * -9/10 = 18/30 = 3/5
So, option B is your answer.
Hope this helps!
Rational numbers are basically numbers which are in the form of p/q where p and q are not equal to 0
Therefore p can be both +ve and -ve
But Natural numbers start from 1 , ie they are always positive
Therefore the answer is
B. sometimes
13. Supplementary angles are two angles that add up to 180 degrees.
3x + x = 180
Combine like terms:
4x = 180
4x divided by 4 = x
180 divided by 4 = 45
x = 45
Equation:
3(45) + 45 = 180
135 + 45 = 180 (TRUE STATEMENT)
Angle A = 135 degrees
Angle B = 45 degrees
This is correct as 135 + 45 adds up to 180 (making it a supplementary angle) AND 135 is 3 times bigger than 45 so it fits the answer’s standard.
Ima do number 14 in the comments as I don’t want to take too long to show number 13.
This means 11 + 1÷8
So 11 + 0.125
Final answer 11.125
Hope you understand :)
First year- $1,887.5
second year- $1,497
third year- $1,958.5
fourth year- $2,242.5
fifth year- $2,065
sixth year- $1,674.5
And if you needed it to be added together, for the total income over those six years, its $7,479
