Answer:
Janelle's conclusion is correct, because the value of x is 15
Step-by-step explanation:
step 1
Find the value of x
we know that
m∠MKJ=m∠LKM+m∠LKJ
substitute the given values and solve for x
80°=(2x+10)°+(3x-5)°
80=5x+5
5x=80-5
5x=75
x=15
step 2
Find the value of x assuming that KL bisect the angle MKJ
so
m∠LKM=m∠LKJ
(2x+10)°=(3x-5)°
3x-2x=10+5
x=15
therefore
Janelle's conclusion is correct, because the value of x is 15
To multiply decimals pretend there is no decimal for example
.165*74 = 12210; then however many digits (not counting zeros) is after the decimal added together (from both numbers) so 3 so 12.21 is the answer
Answer:
The variable is usually the unknown part of the whole.
Answer: x=-3/4
Step-by-step explanation:
Since we know f(x)=6, we can set it equal to the equation.
6=9+4x [subtract 9 on both sides]
-3=4x [divide both sides by 4]
x=-3/4
