Answer:
Simone is correct
Step-by-step explanation:
Given
Line 1:
Line 2:
Required
Is Simone correct?
Slope (m) is calculated using:
For Line 1
For Line 2:
Divide by 2/2
By comparison, both lines have the same slope.
Hence, Simone is correct
Cost of one pretzel is $2.5 and cost of one ice cream is $4.5
Step-by-step explanation:
Let,
Cost of pretzel = x
Cost of ice cream = y
According to given statement;
the cost of a pretzel is $2 less than the cost of some ice cream.
x = y - 2 Eqn 1
five ice creams cost the same as nine pretzels.
9x = 5y Eqn 2
Putting value of x from Eqn 1 in Eqn 2
Dividing both sides by 4
Putting y=4.5 in Eqn 1
Cost of one pretzel is $2.5 and cost of one ice cream is $4.5
