Answer:
50 grams
Step-by-step explanation:
Let the amount of cheese required by the recipe be "x"
Ann increased 60% from original amount and then used up 80 grams. Thus:
<em>Original, increased by 60%, became 80</em>
<em />
This translated to algebraic equation would be:
x + 0.6x = 80
<u>Note:</u> 60% = 60/100 = 0.6
So we can solve the above equation for "x" and get our answer. Shown below:
Hence,
the recipe required 50 grams of cheese
Answer:
Option (4)
Step-by-step explanation:
Slope a line passing through two points and
is given by,
m =
Since, blue line is passing through two points (-4, -2) and (0, 4),
Slope of the blue line =
=
Similarly, green line is passing through two points (-4, 1) and (0, -2),
Slope of the green line =
=
Since,
Neither these slopes are opposite reciprocals.
Therefore, both the lines are neither parallel nor perpendicular.
Option (4) will be the correct option.
