The answer to the question is A
The value of x and y is 5 , 7
<h3>What is an Equation ?</h3>
An expression consists of variables , constants and mathematical operators , when equated by any other algebraic expression or a constant it becomes an equation.
The equation given in the question is
(x + 1)/2 -(y+4)/11 = 2
(x+3) /2 + (2y+3)/17 = 5
It has to be solved for x and y ,
The simplification of the equation has to be done
and the equation is
11x-2y = 41 -----------1
and
17x +4y = 113 -------------------2
to find the solution elimination method will be followed as
Multiplying equation 1 by 2 and adding the both equations
39x = 195
x = 5
Substituting this value in equation 1
55 -2y = 41
y = 7
The value of x and y is 5 , 7

Answer:
Step-by-step explanation:
Given
Required
Rewrite in logarithmic form
We start by taking log of both sides
From laws of logarithm;
So; becomes
Divide both sided by log3
From laws of logarithm;
So;
becomes
Hence, in logarithm form is
The place the value of 9 is in is the hundreds place. So, any number greater than 5 is rounded up. 7 is greater than 5, so the 9 becomes a 0 and the next number is increased by 1. All the values after are marked as a 0. The answer is 223,000.
