Answer:
I think the answer is C
Step-by-step explanation:
First you need to find 2 coordinates on the graph. (2,3) (4,6)
Use the formula M= y2-y1 ÷ x2-x1
Then m= 6-3 ÷ 4-2
Then m= 3÷2 = 1.5
So the slope should be 1.5 or 1 1/2
Answer:
The quantities used by Manuela were correct
Step-by-step explanation:
The question is
Did Manuela use the right quantities?
Let
x -----> the parts of oil
y ----> the parts of vinegar
we know that
The ratio of the parts of oil by the parts of vinegar of recipe is
Determine the relation used by Manuela
Compare with the recipe
Is true, the quantities are proportional
therefore
The quantities used by Manuela were correct
Answer:
6/25 x 3/4 = 18/100 % 16/5 = 18/100 x 5/16 = 90/1600 or 0.05625
Can also be simplified to 9/160
54
a rule I follow:
same signs positive,
different signs negative.
-9 * -3 = 27
27 + 27 = 54
Put the first number on top then start adding 6+0, 8+1, 0+4, 1+1, 0+0 and the answer is 69420
