Answer: A)
B) 75%
C) She bought 1.5 dozen of plain bagels and 0.5 dozen of sesame bagels.
Step-by-step explanation:
Given: The ratio of the number of sesame bagels to the number of plain bagels is 1:3.
Let the number of sesame bagels be x and the number of plain bagels be 3x.
Then total bagels=x+3x=4x
A) The fraction of bagels are plain
B) The percent of bagels are plain
C) If ill bought 2 dozen bagels, the number of plain bagels
The number of sesame bagels
Hence, she bought 1.5 dozen of plain bagels and 0.5 dozen of sesame bagels.
your welcome ;)
Are we finding x? Or are we solving the equation with x
First step is to distribute.
-4a^2 - 6a +2 + 3a^2 -3
Combine like terms
-a^2 -6a -1

Step-by-step explanation:
Answer:
slope =
and -
, perpendicular
Step-by-step explanation:
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
y =
x + 11 is in this form with m = 
Rearrange 7x + 3y = 13 into this form
subtract 7x from both sides
3y = - 7x + 13 ( divide all terms by 3 )
y = -
x +
← in slope- intercept form
with m = - 
• Parallel lines have equal slopes
• The product of perpendicular slopes = - 1
The lines are not parallel since slopes are not equal
× -
= - 1
Hence lines are perpendicular
