Answer:
12 and 16
Step-by-step explanation:
set up an equation:
since one number is 4 less than the other, let x represent it. for the other number, let x+4 represent it since it's 4 greater than x. set the equation equal to 28 because the sum of the two numbers is 28.
x+x+4=28
now, we solve the equation:
x+x+4=28
2x+4=28
2x=24
x=12.
Since x equals 12, to find the other number, which would be 4 greater than x, we would add:
12+4=16
So, the two numbers are 12 and 16.

Answer:
Step-by-step explanation:
d=20t+1/3, b=30t
20t+1/3=30t
10t=1/3
t=1/30 hr
t=(1/30)60=2 min
Answer:
A
Step-by-step explanation: im not extremely sure about this one though but the x coordinate is nine away from every coordinate of defc and the way it goes left means that the x is negative, the y coordinates of defc prime is positive because it moves up from defc. hope this helps
