x+y=6 and 20x+30y=140 can be used to determine the number of each type of lawn mowed by Sarah.
Step-by-step explanation:
Given,
Charges for cutting small lawns =$20
Charges for cutting large lawns = $30
Total yards mowed = 6
Total amount earned = $140
According to given statement;
x+y=6 Eqn 1
20x+30y=140 Eqn 2
x+y=6 and 20x+30y=140 can be used to determine the number of each type of lawn mowed by Sarah.

Answer:
a) BE = 5; DE = 6; EF = 4
b) ∠EFC ≅ ∠DA.F ≅ ∠BDE or <em>b = e = f = i</em>
Step-by-step explanation:
Each short segment is the same length as the marked one it is parallel to.
E is the midpoint of BC, so BE = EC = 5.
ADEF is a parallelogram, so DE = A.F = 6.
D is the midpoint of AB, so AD = DB = 4. ADEF is a parallelogram, so ...
EF = AD = 4
__
As we have noted, AB║EF and DE║A.F, so corresponding angles and alternate interior angles are congruent. <em>b = e = f = i</em>
