Answer:
I believe the answer is D
Step-by-step explanation:
Answer is 16
8 (6 1/4 x 3.2 - 18)
8 ( 6x4+1) = 25/4
8 (25/4 x 3.2 - 18)
8 (25/4 x 3.2) = 80/4 = 20
8 (20 - 18) = 2
8 x 2 = 16
Answer:
86°
Step-by-step explanation:
Given:
A = (6x + 10)°
B = (4x +30)°
Two angles are supplementary if they sum up to 180° ;
A + B = 180°
Now insert the parameters and solve;
6x + 10 + 4x +30 = 180
10x + 40 = 180
10x = 140
x = 14
So;
B = (4x +30)° = 4(14) + 30 = 86°
the difference between a proper fraction and an improper fraction is an improper fraction is a fraction that is bigger then the denominator for example 3/4 is a fraction and 7/4 is an improper fraction
