Let the variable "b" represent the number of bagels you buy
let the variable "R" represent the amount of money you have left
R = 25 - 1.25b
is your equation
then to find out after you bought 2 bagels
R = 25 - 1.25(2) = 25 - 2.5 = 22.5
do you would have $22.50 left on the card after you buy 2 bagels
Answer:
Step-by-step explanation:
Segment
A segment is a line that has 2 end points. We can measure the segment length. A segment is represented by
where A and b are the two end points of the segment.
Ray
A ray is an line that has one end point and one point goes in infinity. We cannot measure ray as it's one end goes to infinity. A ray is represented by
where A is the end point and B is the infinite point.
Figures of ray and segment are attached.
Answer:
either you have 62.6 + 62.5 + 55
or you have 55 + 55 + 70
Step-by-step explanation:
There are only two possible answers.
Either 55 degrees is by itself and the two equal angles are something other than 55 in which case you would write it as
x + x + 55 = 180 Subtract 55 from both sides
2x + 55 - 55 = 180 - 55
2x = 125 Divide by 2
x = 125/2
x = 62.5
OR
There are 2 angles that are both 55
x + 55 + 55 = 180
x + 110 = 180
x = 70
Answer:
4x²
Step-by-step explanation:
Your equation is 4x² - 6x² + 7x² - 20x² + 19x².
Since they all have the same variable, simply combine them all to find your answer.
4x² - 6x² + 7x² - 20x² + 19x²
-2x² + 7x² - 20x² + 19x²
5x² - 20x² + 19x²
-15x² + 19x²
4x²
