Answer:
D, 64%
Step-by-step explanation:
To solve algebraic equations, you have to do the inverse or opposite, so because you are multiplying x by 50 on one side and x wants to be alone, you have to do the opposite which is divide by 50 to get x*1 or just x (because 50/50 equals 1) and what you do on one side of the = sign you do on the other, so 32/50 = 0.64. Then to make a percent you move the decimal to the right by 2 places and you get 64%
9/8 + 9/4 = 27/8.
Multiply 9/4 by 2.
9/4 • 2 = 18/8
Then, add the fractions.
9/8 + 18/8 = 27/8
Simplify 27/8.
27/8 = 3 3/8
Alan is 14 years old
He is twice as old as James
then Alan is the elder brother
Alan is twice as old means his age is double the age of James
Alans age = 2 x james age
that means James must be half of Alans age
Alans age = 14 years
James age = 14 / 2 = 7 years
therefore James is 7 years old

Answer:
80 m
Step-by-step explanation:
First convert km/h to m/s.
24 km/h × (1000 m / km) × (1 h / 3600 s) = 6.67 m/s
Distance = rate × time
d = 6.67 m/s × 12 s
d = 80 m
