Answer:
and 
Step-by-step explanation:
The question is incomplete as the attachment to solve segment DE is missing. However, see attached for complete question.
Given

Required
Find x
Length of DE
To find x, we need to first simplify the given equation

Multiply both sides by 



Subtract 15 from both sides


Divide both sides by 10



From the attached;

Substitute 6.6 for x



Hence
and 
Answer:
53
Step-by-step explanation:
Mean=Average
To find it, add al the numbers and divide by how many there are.
48+59+70+27+61=265
265/5=53

Answer:
133 fishes
Step-by-step explanation:
Units of food A = 400 units
Units of food B = 400 units
Fish Bass required 2 units of A and 4 units of B.
Fish Trout requires 5 units of A and 2 units of B.
i. For food A,
total units of food A required = 2 + 5
= 7 units
number of bass and trout that would consume food A = 2 x 
= 114.3
number of bass and trout that would consume food A = 114
ii. For food B,
total units of food B required = 4 + 2
= 6 units
number of bass and trout that would consume food B = 2 x 
= 133.3
number of bass and trout that would consume food B = 133
Thus, the maximum number of fish that the lake can support is 133.
5t = 25+2r
t = (25+2r)/5 or
t = 5 + (2/5)r
The area of a trapezoid with base lengths 7 in and 19 in is given by
A = (1/2)(b1 + b2)h
A = (1/2)(7 +19)·7 = 91
The appropriate choice is
D. 91 in²
_____
It can also be figured by adding the area of the 7 in square (49 in²) to the area of the 7×12 in right triangle (42 in²).
