Answer:
Carmen bought 5 pounds of coffee
Step-by-step explanation:
The cost of buying coffee is $8.44 per pound. Let us assume she bought x pound of coffee, this means that she spent $8.44x on coffee.
She went to the coffee store with $80 gift card and left with $37.80, this means that after spending $8.44x from the initial $80, she had $37.80. To find the number of pounds she bought, we are to use the following equation:
80 - 8.44x = 37.80
8.44x = 80 - 37.80
8.44x = 42.2
x = 42.2/ 8.44 = 5
x = 5 pounds.

Answer: Rise = 3 Run=1 slope=3/1 or just 3
Step-by-step explanation:
start at the left most point and count up to the line that contains the 2nd point
so rise 3
then count over to that 2nd point
so run is 1
slope is rise/run so 3/1
I would multiply both sides by negative one and then take the smaller of the two variables and subtract that from both sides, simplify and solve.
