Answer:
A. 10.00, so total price is currently 40.00
B. 42.8
C. Total amount is 51.36
Step-by-step explanation:
20% of 50 is 10. Taking off 10% (your discount) would make it 40.
7% of 40 is 2.8. The total amount is now 42.8
20% (your tip) of 42.8 = 8.56.
42.8 + 8.56 = 51.36.
51.36 is your final cost.
Answer:
40 mi
Step-by-step explanation:
a² + b² = c²
24² + 32² = c²
1600 = c²
√1600 = c
c = 40
X(7x+3)=0
x=0
or
7x=-3
x=-3/7
so,
(0,0) or (-3/7,0)
