Answer:
a=5, b=15
Step-by-step explanation:
we know that
The figure MNLO is a Kite
so
LO=NO and MN=LM
we have
LO=7a-14, NO=b+6
7a-14=b+6 -----> equation A
MN=b, LM=3a
b=3a -----> equation B
Solve the system of equations by substitution
Substitute equation B in equation A and solve for a
7a-14=(3a)+6
7a-3a=6+14
4a=20
a=5
Find the value of b
b=3a ----> b=3(5)=15
therefore
a=5, b=15
Im not sure what you are asking is there another part to the question.
Answer:
Step-by-step explanation:
A.123.50≤20+10(x)
103.50≤10x
10.35 hours at least to equal the 123.50.
10.35 hours *10 an hour is 103.50+20 flat fee=123.50
B. 123.50≤15(x)
8.24 hours or more. 15.00 an hour at 8.24 hours = 123.60
C. He will work less hours if he charges more and does not charge the flat fee.
