Is this the full question that is stated?
Answer: x = 6.8
or x = 102/15
Step-by-step explanation:
30x=204
204/30
simplify!
Answer: y= x-2
Step-by-step explanation:
Perpendicularity entails the slope of line a is -1 divided by the slope of line b
m1= (-1/m2)
From y=Mx +c
We compare with x-4y=7
y=(1/4)x-7/4
Meaning m2= 1/4
m1= -1/(1/4)= -1*4= -4
((y-y1)/(x-x1))= ((y2-y1)/(x2-x1))=m1
x1= 2, y1= -4
((y-(-4))/(x-2))= -4
((y+4)/(x-2))= -4
Cross multiply
y+4= -4(x-2)
y= x-2
Answer:
Step-by-step explanation:
We are given the length of the whole line and its two halves. Since JK and KL make up the line JL, adding them together would make the line JL.
Now we can plug the value of 
back into the expression we were given for the line KL.
Answer:
2
Step-by-step explanation:
1st step: solve the exponential number
2x^2=4x
3x^2=9x
2nd step: rewrite the number sentence with the exponent solved
4x-8x+8 9x+27x-30
3rd step : solve
4x-8x=-4x 9x+27x=36x
-4x+8= 36x-30=
4 6
Step 4: See what least common multiples they have in common
4 LCM =2 * 2= 4 6 LCM= 2*3=6
So the LCM is 2
