-2log_5 7x = log_5 2
log_5[1/(7x)^2] = log_5 2
log_5(1/49x^2) = log_5 2
log_5(1 - 49x^2) = log_5 2
1 - 49x^2 = 2
You finish.
Think about c/3 =4/1 and apply the cross multiplication rule since those two fractions are equal.
We get c•1= 3•4
c=12
Answer:
8 hours
Step-by-step explanation:
because each hour that goes by the buses go a distance of 117 miles apart from each other (53+64) you must divide the total distance by the 117 mph distance for a total of 8 hours (936 / 117 = 8)
Answer:
x = -1.6
Step-by-step explanation:
To find the value of x
4x - 5 = -6x - 21
Transpose
4x + 6x = -21 + 5
10x = -16
x = -16/10
x = -1.6
