Today, Isaac needs to walk his dog, water the garden, and feed his fish. D is the number of minutes it takes
to walk his dog, G is the number of minutes it takes to water the garden, and F is the number of minutes it
takes to feed his fish.
The expression G + D + F describes the total number of minutes it takes Isaac to do all three tasks.
We can also use the expression (G+D) + F to represent the same quantity.

is this part of a question or something

according to egenuity the answer is

step-by-step explanation:

d. 344.22

(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
