The additive inverse of -4b is 4b
X= weight of TV
y= weight of CD
3x+5y= 62.5
3x+ 2y= 52
You can either solve for a variable, or eliminate a variable by subtracting the second equation from the first:
3x + 5y = 62.5
-(3x+2y = 52)
0 + 3y = 10.5, so y = 10.5/3 or 3.5.
Now plug y= 3.5 back into any equation to get x:
3x + 5(3.5) = 62.5
3x + 17.5 = 62.5
3x = 45
x = 15
Always check work. Both equations should be true for x=15, y= 3.5
Answer:
The segment opposite to angle D is CF.
Step-by-step explanation:
To find what angle is opposite to a side. All you just have to do is see which segment doesn't touch that angle. We see that angle D does not touch CF, so angle D must be opposite to CF.
Hello from MrBillDoesMath!
Answer:
88
Discussion:
Angle Q is an inscribed angle so
measure angle Q = 44 =
(1/2) measure of intercepted arc.
In other words,
44 = 1/2 mST => multiply both sides by 2
m ST = 44*2 = 88
which is the second choice
Thank you,
