Calculate how much each size per gram, and circle which gives the best value for money. 250g for $2.30, 400g for &3.40, 1Kg for $5.65
Answers
Option One:
The first options costs only $0.0092/gram (a fraction of a penny)!
Option Two:
The second option costs only $0.0085/gram (cheaper than option one)!
Option Three:
This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore, 1,000g costs $5.65. Next, we set up the ratio as usual:
The third option costs $0.00565/gram.
Therefore, option three is the cheapest!
Hope this helps!

Final answer:
A fraction between 3/4 and 4/5 can be found using averaging. By converting these fractions to decimal equivalents, adding them together, and dividing by 2 we get 0.775, which is equivalent to the fraction 31/40.
Explanation:
To find a fraction between 3/4 (0.75) and 4/5 (0.8), we can use an approach called averaging where we add both fractions and divide the sum by 2. Using decimal equivalents can make the calculation more straightforward. You add 0.75 and 0.8 to get a sum of 1.55, then divide by 2 to get 0.775. A fraction equivalent to 0.775 is 31/40, which is between 3/4 and 4/5.

Answer:
The graph is not a function of x because the line x = 0 intersects the graph at two points.
Step-by-step explanation:
This graph is not a function because it fails the vertical line test, since several vertical lines would intersect the graph at 2 points.
This answer choice is correct, as the line x = 0 intersects the graph at 2 points, (0, 2) and (0, -2).

Answer:
- x = 40
- y = 22
Step-by-step explanation:
We know that:
- x - y = 18
- x + y = 62
Work:
- x - y = 18
x + y = 62
- => (x + x) + (y - y) = (18 + 62)
- => 2x + 0 = 80
- => 2x = 80
- => x = 40
To find y, let's use any equation in the "we know that" section.
- => 40 - y = 18
- => 40 - 18 = y
- => 22 = y
Now, let's check our work by using the second equation.
Check:
- x + y = 62
- => 40 + 22 = 62
- => 62 = 62 (Proved correct)

What is the slope of a line perpendicular to x - 3y = 9?
What is the slope of a line parallel to 10x - 5y = 8?
What is the slope of a line parallel to 4x + 2y = 5?
Answers
-5y = -x - 10
y = 1/5x + 2.....slope here is 1/5...perpendicular line needs a negative reciprocal slope. All that means is flip the slope and change the sign.
1/5......flip.....5/1.....change the sign....-5/1...or just -5 <== answer
slope of line parallel to 4x + y = -1
y = -4x - 1...slope here is -4....parallel lines will have the same slope
answer is : -4
slope of line perpendicular to x - 3y = 9
-3y = -x + 9
y = 1/3x - 3....slope = 1/3.....flip...3/1....change sign...-3 <== answer
slope of line parallel to 10x - 5y = 8
-5y = -10x + 8
y = 2x - 8/5....slope = 2....parallel lines have same slope...answer = 2
slope of line parallel to 4x + 2y = 5
2y = -4x + 5
y = -2x + 5/2.....slope = -2
y=-3x would be perpendicular to x - 3y = 9
y=-2x would be parallel to 10x - 5y = 8
y=2x would be parallel to 4x + 2y = 5
