Answer:
x = -3
Step-by-step explanation:
You can try the answers to see which works. Or, you can actually solve the equation for x.
... 7 - log2(x+5) = 6
... 1 - log2(x+5) = 0 . . . . subtract 6
... 1 = log2(x+5) . . . . . . . add log2(x+5)
... 2 = x +5 . . . . . . . . . . . take the antilog
... -3 = x . . . . . . . . . . . . . subtract 5
Answer:
volume
Step-by-step explanation:
Answer:
12x6+2(6-1)
72+2x5
72+10
82
82 is the answer.
Step-by-step explanation:
Just replace the X's in the problem with 6.
Answer:
Speed of a= 21 miles/hr
r = Speed of b= 7 miles/hr
Speed of a = 3r
Step-by-step explanation:
The cyclist are 112 miles apart
Time traveled by two = 4 hours
Speed of a = 3 * speed of b
If a cylcles 3 times More than b, then a will cover 3*distance of b
But speed = distance/time
Time = 4hours
Total distance=112
a = 3b
3b + b = 112
4b = 112
b = 112/4
b = 28 miles
a = 3b
a = 3*28
a = 84 Miles
They bought traveled 4 hours
Speed of a = 84miles/4 hours
Speed of a= 21 miles/hr
Speed of b = 28miles/4 hours
Speed of b = 7 miles/hr
Answer:
The system of linear equations is x + y = 64 and x = y + 14.
Given that,
The total number of students is 64 .
Here we assume the x be the number of students in filmmaking club .
And, y be the number of students in yearbook club.
Based on the above information, the calculation is as follows:
x + y = 64
And,
x = y + 14
Therefore,
We can say that
Number of students in yearbook club = 25
And, the number of students in filmmaking club = 39
