Answer:
first we should add both purchase price
$4.45 + $9.55 = $14
so that
$20 - $14
=$6
Answer:
Step-by-step explanation:
If he travels 5/2 miles in 15 mins, then in 1 min he will travel 5/2 ÷ 15 = 1/6 miles and it will take him 15 ÷ 5/2 = 6 mins to travel 1 mile.
Answer:
1) y = 1/2 x + 3 and y = 1/2 x are parallel
2) y = 1/2 x + 4 and y = 1/2 x + 1 are parallel
Step-by-step explanation:
Two lines are parallel only if their slope is equal.
1)
In the first problem:
y = 1/2 x + 3 and y = 1/2 x have same slope ( i.e slope = 1/2)
That means these two equations are parallel to each other.
2)
In the second problem:
y = 1/2 x + 4 and y = 1/2 x + 1 have same slope( i.e slope = 1/2)
Hence above two equations are parallel to each other.
