Answer:
The first one on the left
Step-by-step explanation:
Part A
Total number of litres in the punch = grape juice + lemon lime soda
let grape juice be
, and lemon-lime soda be
the expression for the total number of litres in the punch is given by
We know the number of litres for the lemon-lime soda, hence the expression is
Part B:
40% of the punch is lemon-lime soda which is 2 litres
That means every 1 litre represents 20% of the punch
60% of the punch is grape-juice, hence 60÷20 = 3 litres of grape juice
54+36=90<span>90÷6=15
So 15 is your answer</span>
Answer:
never
Step-by-step explanation:
Any triangle can never be a parallelogram because it only has three sides.
quadrilateral with parallel sides is a parallelogram.
In order to answer this, you need to find the equation of the line. The equation of a line is y= mx + b; mx being the slope and b being the y- intercept. The y intercept is located at (0, 20).
To find the slope, take two points. Let's use (1,40) and (2,60).
Use the slope formula: (y1 - y2)/(x1 - x2)
(60-40)/(2-1)= 20/1= 20.
The slope is 20, the equation is: y = 20x + 20.
Now plug 10 into x:
y = 20(10) + 20
y = 220
Your answer is 220.
