Answer:

7.8125 gallons

Step-by-step explanation:

1600 / 5 = 320 square-foot wall.

So to cover 2500 square foot-wall, we need in total of:

2500 / 320 = 7.8125 gallons of paint

Graph the system of equation on graph paper or in your calculator, y=−4/3x+4y=−2/3x−2
aleksklad [387]

Answer:

The lines intersect once at (2, −1).

A graphic solution to a system of equations is only as accurate as the scale of the paper or precision of the lines. At times the point of intersection will need to be estimated on the graph. When an exact solution is necessary, the system should be solved algebraically, either by substitution or by elimination.

Andrea has just created a scale drawing of her bedroom room which is 18 feet long by 12 feet wide. The scale drawing shows the l
vivado [14]

Width of the scale drawing is 4 inches

Step-by-step explanation:

We can solve this problem by using the rule of three.

In fact, the actual size of the bedroom are:

L=18 ft (length)

W=12 ft (width)

In the drawing instead, the actual sizes on scale are

L' = 6 in (length in the scale drawing)

W' (width in the scale drawing)

Therefore, applying the rule of three,

\frac{L'}{L}=\frac{W'}{W}

And solving for W', we find the width on the scale drawing:

W'=\frac{L'W}{L}=\frac{(6 in)(12 ft)}{18 ft}=4 in

So, the width on the scale drawing is 4 inches.
