If is was a property in think it would be Identity Property of Addition
In order to determine how log will take for 8 people to pave a driveway you use the given proportion: 3 people pave a driveway in 4 hours.
By a simple rule of three you have:
3/4 = 8/x
Where you have peeple in the numerator and time in hours in the denominator.
You solve the previous equation for x:
3/4 = 8/x
x = (8/3)*(4) = 32/3 = 10.66
Then, 8 people will take approximately 10 hours plus 40 minutes to pave a driveway
Answer:
B, C
Step-by-step explanation:
Since y=0, you are looking for equations such that 10 times the coefficient of x is the constant in the equation.
a) 5·10 ≠ 15
b) 2·10 = 20 . . . . select this one
c) 10 = 10 . . . . select this one
d) 3·10 ≠ 13
e) 4·10 ≠ 20
f) 6·10 ≠ 50
Answer: =7y^2+20y−3
Step-by-step explanation:
A) 49.99m+59.99
B) for one year= 12 months
m=12
49.99(12)+59.99
=659.87$ for one year
