Answer:
£5.04
Step-by-step explanation:
Let's first find the unit cost.
£3.60/2.5kg = £1.44/kg
To find out how much money 3.5kg of apples costs, we simply need to multiply the unit price by 3.5.
£1.44/kg * 3.5kg = £5.04.
Answer:
This should be parallel.
Step-by-step explanation:
Two lines are said to be parallel only if their slope matches. They are said to be perpendicular only if the slopes are negative reciprocals.
Here, you should put both equations in slope intercept form which is y=mx+b. The letter "M" represents the slope of both equations.
2y-6=3x+4 turns into 2y=3x+10 after adding 6 and into y=3/2x+5 after dividing the equation by 2. The slope for this equation is 3/2.
8y=12x+8 must be divided by 8 to be in slope intercept form. This equation becomes y=3/2x+1. Here the slope is also 3/2.
The slopes for each equation match making these lines parallel.
