Evan jarred 10 liters of jam after 2 days. How many days does Evan need to spend making jam if he wants to jar 15 liters of jam in all? Assume the relationship is directly proportional.

Find liters per day by dividing the amount made by the number of days :

10 liters / 2 days = 5 liters per day.

Find how much more he needs to make by subtracting the amount made from the total he wants:

15 liters - 10 liters = 5 liters more needed.

Divide amount needed by time:

5/5 = 1

He will need to spend 1 more day, which means he will spend a total of 3 days to make 15 liters.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
