Answer:
According to logarithmic properties.... The right hand side can be written as
log base 7 (180/3).....which is log base 7 60
So according to the question cancel out the log base 7 from both sides....
Then we get 8r + 20 = 60
That is 8r = 40..
That is r = 5......
Therefore the value of r is 5

Answer:
12/16
Step-by-step explanation:
multiply 3/4 in the numerator and denomanator by 4 and you get 12/16
The system has:
- No solutions for two parallel lines.
- 1 solution for two nonparallel lines.
- Infinite solutions for two equations that describe the same line.
<h3>How to identify the number of solutions for the systems?</h3>
A system of two linear equations is given by:
y = a*x + b
y = c*x + d
1) The system has no solutions when both lines are parallel lines, this happens when both lines have the same slope and different y-intercept.
y = a*x + b
y = a*x + d
2) The system has one solution when the lines have different slopes:
y = a*x + b
y = c*x + d
3) The system has infinite solutions when both equations describe the same line:
y = a*x + b
y = a*x + b

Answer:
a. The ratio of A to B is 2.92 : 1
b. The ratio of B to A is 1 : 2.92
c. A is 292% of B
Step-by-step explanation:
A = 52193
B = 17878
a. The ratio of A to B is: 52193 : 17878
To get the ratio in lower form, divide A with B (since it is the smallest of the two value) and the result is:
2.92 : 1
b. The ratio of B to A is: 17878 : 52193
1 : 2.92
c. The percentage of A to B is:
