The value of x that makes ABC~ RTS. is 12
<h3>How to determine the value of x?</h3>
From the figure, we have the following equivalent ratio:
2x + 6 : 40 = 36 : 48
Express as fraction
(2x + 6)/40 = 36/48
Multiply both sides by 40
2x + 6 = 30
Subtract 6 from both sides
2x = 24
Divide both sides by 2
x = 12
Hence, the value of x is 12

Answer:
13 degrees
Step-by-step explanation:
mPQR=25 degrees , mRQT=11 degrees.
mPQT=PQR-RQT
MPQT=25-11=13 degrees
Make f(x) = y
y = (15x + 50)/(x + 5)
Swap the x and y and make y the subject again
x = (15y + 50)/(y + 5)
x(y + 5) = 15y + 50
xy + 5x = 15y + 50
xy - 15y = 50 - 5x
y(x - 15) = 50 - 5x
y = (50 - 5x)/(x - 15)
So inverse function f^-1(x) = (50 - 5x)/(x - 15)
Answer:
-137
Step-by-step explanation:
The difference between two numbers can be found through subtraction.
-45 - 95 = -137.
