500×12%
(500×12)÷100
6000÷100
=60
so,
500+60=560
Answer:
x=8, y=4
Step-by-step explanation:
7x + 10y = 96
5(5x - 2y = 32)
7x + 10y = 96
25x - 10y = 160
32x = 256
x = 8
7(8) + 10y = 96
56 + 10y = 96
10y = 40
y = 4
Answer: 28.8%
Step-by-step explanation:
First find out what her speed is:
Speed = Distance / Time
= 50 / 45
= 1.11 meters/second
Now her speed is:
= 50 / 35
= 1.43 meters/ second
The percentage increase in her speed is:
= (New speed - Old speed) / Old speed
= (1.43 - 1.11) / 1.11
= 0.288
= 28.8%
