Given that D is the mid point of CE ,
So D will bisect CE, it means the length of DE and CD is equal.
=> DE + CD = CE
As DE and CD are equal,
=> DE + DE = CE
=> 2 DE = CE
Putting values from the question,
=> 2( 7x - 1 ) = 10x + 18
=> 14x - 2 = 10x + 18
=> 14x - 10x = 18 + 2
=> 4x = 20
=> x = 20 / 4
=> x = 10 / 2
=> x = 5
Therefore, the value of x is 5
Answer:
51.9
8.9
78.5
8.8
Explanation:
You round up if the number to the right is 5 or greater.
So, apply this to the numbers and the 8 in A rounds up, going to a 51.9.

The 5 also does not round up because of the 2.
The 7 does round up because of the 6.
Answer:
Step-by-step explanation:
Given that the owner of a motel has 2900 m of fencing and wants to enclose a rectangular plot of land that borders a straight highway.
Fencing is used for 2times length and 1 width if highway side is taken as width
So we have 2l+w = 2900
Or w = 2900-2l
Area of the rectangular region = lw
Use derivative test to find the maximum
So maximum when I derivative =0
i.e when 
Largest area = A(725)
= 
1051250 sqm is area maximum

Answer:
dryer cost = $450
Step-by-step explanation:
Given that:
washer + dryer = $841 ---- eq1
As washer costs $59 less than dryer So,
Dryer - $59 = washer
putting in eq1
Dryer + dryer - $59 = $841
2 dryers = $841 +$59
Dryer = $900/2
Dryer = $450
So the cost of washer will be:
washer = dryer - $59
Washer = $450 - $59
washer = $391
i hope it will help you!
