If M is the midpoint of JK then JM+MK=JK and JM=MK
so
6x-7=2x+3
minus 2x both sides
4x-7=3
add 7 both sides
4x=10
divide both sides by 4
sub back
JM=6x-7
JM=8
JM=MK=8
JM+MK=8+8=16=JK
and JM=8=MK and JK=16
4x + 2 = 62
4x = 62 - 2
4x = 60
x = 60/4
x = 15 <===
12y = 144
y = 144/12
y = 12 <===
alternate interior angles are congruent
The answer is 360 10 times 12
Answer:
(4x -14)/3
Step-by-step explanation:
Assuming you intend mixed number coefficients, only the coefficients of x can be combined.
(-2 1/4)x +(3 7/12)x -(4 2/3) = x(-2 1/4 +3 7/12) -(4 2/3)
The mixed numbers are added in the usual way.
(-2 1/4) +(3 7/12) = (-2 +3) +(-1/4 +7/12) = 1 +(-3/12 +7/12) = 1 4/12 = 1 1/3
So the expression simplifies to ...
(1 1/3)x -(4 2/3)
This might be better written as ...
(4x -14)/3

<em>Comment on mixed numbers</em>
It is hard to write mixed numbers so they can be properly interpreted in an algebraic expression. In general, they are better written as improper fractions or as decimal numbers (if the decimal terminates).
Answer: 7/3
Step-by-step explanation:
1. you multiply 2/7 on both sides to get x by it self.
2. then you can cross out both the 2's and get 7/3 as the final answer.
