Answer: it means multiplication
Step-by-step explanation:
Rate = 5.5 miles/s
Time to reach 2 miles
2 / 5.5
0.364 s
5x + 10y = 50
x + y = 8
x = 8 - y
5*(8-y) + 10y = 50
40 - 5y + 10y = 50
10y - 5y = 50 - 40
5y = 10
y = 2
x + y = 8
x + 2 = 8
x = 8 - 2
x = 6
She has 6 nickels and 2 dimes
|x＋8|=5
then x+8= 5 or -5
then x= -3 or -13
