On Thursday, a local hamburger shop sold a combined total of 327 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Thursday?

The number of hamburgers is 109.

Step-by-step explanation:

Let h = number of hamburgers

Let c = number of cheeseburgers

The total number sold gives us the equation below.

h + c = 327

"The number of cheeseburgers sold was two times the number of hamburgers sold.

This gives us the equation

c = 2h

Now we substitute c with 2h in the first equation and solve for h.

h + 2h = 327

3h = 327

h = 109

The number of hamburgers is 109.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
