Answer:
Step-by-step explanation:4log(5) = log(5^4) = log(625).
This problem involves using one of the properties of logs, where a coefficient (in this case the "4") for a logarithm equals the "inside of a logarithm" raised to power of whatever number the coefficient is.
The property in mathematical terms is: Alog(B) = log(B^A).
So, 4log(5)= log(5^4) = log(625)

Answer:
The value of 7u + 2 is 9.
Step-by-step explanation:
To solve this problem, we first must find the value of u given the second equation. The first step in simplifying this equation is to subtract 8 from both sides of the equation. This is modeled below:
-2u + 8 = 6
-2u + 8 - 8 = 6 -8
-2u = -2
Next, we can divide both sides by -2 to get the variable u alone on the left side of the equation.
-2u/-2 = -2/-2
u = 1
Therefore, the correct answer is u = 1. Now, we can plug in this value for u into the expression that is given.
7u + 2
= 7(1) + 2
= 9
Thus, the correct answer is 9.
Hope this helps!
Answer:
c.180
Step-by-step explanation:
45 times 4= 180
Answer: 120 minutes, 105 km, proportional
Step-by-step explanation:
90 km/hr
180 km * 1 hr/90 km=
180 km/90 km * 1 hr=
2 hours=120 minutes
1 hour=60 minutes
70/60=x/90
7/6=x/90
7*90/6=x
x=7*15
x=105 km
