Answer:
16/3 or 5.3
Step-by-step explanation:
150 miles = 4 hours
Find how long it takes to travel 50 miles(GCF between 150 and 200)
150/3 = 4/3
50 miles = 1 1/3 hours: multiply by 4 to get 200 miles
50 x 4 = 4/3 x 4/1
200 = 16/3
16/3 hours or 5.3
Answer is B x values are greater than or equal to –2.
Answer:
3/8 plus or minus i(√7)/8
Step-by-step explanation:
Complete the square by adding (3/8)^2 to both sides of the equation:
(x -3/8)^2 = -1/4 + (3/8)^2 = -16/64 +9/64
x -3/8 = ±i√(7/64) . . . . . take the square root
x = 3/8 ± i(√7)/8 . . . . . . add 3/8
70% off means she only paid 30% so if x = original price,
54/x = 30/100.
Cross multiply
30x = 5400 so divide by 30
x = $180
