Answer:
x=50
Step-by-step explanation:
angle 1 and 3 are corresponding angles that menas they equal the same
so set it up like this 2x+10=110 solve for x
move over the 10, subtract 10 from 110 you get 100 and divide by 2
you get 50.
Answer:
x - y = -1 ....... 1
3x + 2y = 22 ........ 2
Make x the subject in the first equation
x = -1+y
Substitute this into the second equation
3(-1+y) + 2y = 22
-3 + 3y + 2y = 22
5y = 25
Divide both sides by 5
y = 5
Substitute y = 5 into x = -1+y
x = -1+5
x = 4
x = 4 , y = 5
Hope this helps
Answer:
Step-by-step explanation:
L is the midpoint of KM. So, length of KL = length of LM
KL = LM = 14x
KL + LM = KM
14x + 14x = 26x + 14 {add the like terms}
28x = 26x + 14 {subtract 26x form both sides}
28x - 26x = 14
2x = 14 {divide both side by 2}
2x/2 = 14/2
x = 7
KL = 14x = 14*7
KL = 98
Answer:
number of units for cost to be minimum=150
Step-by-step explanation:
y=2x^2-600 x+49000
dy/dx=4x-600
dy/dx=0 gives 4x-600=0
4x=600
x=150
d^2y/dx^2=4x
at x=150,d^2y/dx^2=4*150=600>0
so y is minimum at x=150
