Answer:
A = 217
B = 45
Step-by-step explanation:
A+B = 262
A - B = 172
A = 172 + B
172 + B + B = 262
2B = 90
B = 45
A = 172 + (45)
A = 217
HOPE THIS HELPS!!!!
<span>Before you can add or subtract
fractions with different denominators, you must first find equivalent
fractions with the same denominator, like this:
<span>Find the smallest multiple (LCM) of both numbers.
<span>Rewrite the fractions as equivalent fractions with the LCM as the denominator.</span></span></span>
Hope i helped!
The relation is that the diameter is twice the length of the radius.
To make more proof, look at the attached image below.

So the solution is (x,y) = (4, -1)
=============================================================
Work Shown:
6x + 7y = 17
6x + 7( y ) = 17
6x + 7( -3x+11 ) = 17 ... replace every copy of y with -3x+11
6x - 21x + 77 = 17
-15x = 17-77
-15x = -60
x = -60/(-15)
x = 4
We'll use this x value to find y
y = -3x+11
y = -3(4)+11 ... replace x with 4
y = -12+11
y = -1
We have x = 4 and y = -1 pair up together to give us the solution (x,y) = (4, -1)
------------------------
To check the solution, we plug x = 4 and y = -1 into each equation
Plugging the values into the first equation leads to...
y = -3x+11
-1 = -3(4)+11
-1 = -1
This is effectively already done in the last part of the previous section. But it doesn't hurt to verify like this regardless.
We'll need to verify the second equation as well.
6x + 7y = 17
6(4) + 7(-1) = 17
24 - 7 = 17
17 = 17
We get a true equation, so the solution is confirmed with both equations. Overall, the solution to the system of equations is confirmed. This system is independent and consistent.
