If there are 1200 calories in one pound of ground beef, how many calories are in 3 oz of ground beef?

The answer is 225 calories are in 3 oz of ground beef.

Step-by-step explanation:

First, you need to know that there are 16 ounces (oz) in a pound. To find how many calories are in each ounce, divide the total amount of calories in the pound by the amount of ounces (16).

1200/16 = 75. So, there are 75 calories in each oz. To find out the amount of calories in 3 oz, you just need to multiply 75 by 3 (since you want to know the amount for 3 ounces).

75*3 = 225.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
