Answer: The numbers are: 16, 11 and 48
Step-by-step explanation:
Let 1st number is a, second number is b and third number is c
1st number is 5 more than the second so a=b+5
The third number is 2 times the first so c=3*a=3*(b+5)
The sum of three numbers, so a+b+c=b+5+b+3*(b+5)=75
b+5+b+3+3b+15=75
5b+20=75
5b=55
b=11
a=b+5=11+5=16
c=3*(b+5)=3*(11+5)=3*16=48
The numbers are: 16, 11 and 48
Answer:
-20
Step-by-step explanation:
-3x - 7y = -5
Multiply each side by 4
4(-3x - 7y) = -5*4
-12x -28y = -20

Let x = time if working together
then
x(1/5 + 1/6) = 1
x(6 + 5) = 30
11x = 30
x = 30/11
x = 2.7273 hours
or
x = 2 hours and 44 minutes
