4x - y = 5 --> 4x = y + 5

substitute

4x + 4y = -4

(y + 5) + 4y = -4

5y + 5 = -4

5y = -9

y = -1.8

solve x

4x = y + 5 = -1.8 + 5 = 3.2

x = 3.2/4 = 0.8

A room is 20 feet by 25 feet with a 10-foot ceiling. If Mickey paints the walls and the ceiling, how much surface area will he c
Svetradugi [14.3K]

Answer:

1400ft²

Step-by-step explanation:

Given

Room Dimension: 20 ft by 25 ft by 10 ft

Where Length = 20 ft

Width = 25 ft

Height = 10 ft

Required

Surface area of painted walls and ceiling

We'll assume that the room is rectangular in shape and all 4 sides are covered.

<em>This means that Mickey will paint 4 walls and 1 ceiling.</em>

The dimension of the 2 of the 4  walls is as follows;

20ft by 10ft, 25ft by 10ft,

Because opposite sides of a rectangle are equal, the dimension of the remaining 2 walls is: 20ft by 10ft, 25ft by 10ft

Calculating the area of the 4 walls;

Area = 20ft * 10ft + 25ft * 10ft + 20ft * 10ft + 25ft * 10ft

Area = 200ft^2 + 250ft^2 + 200ft^2 + 250ft^2

Area = 900ft^2

The dimension of the ceiling is as follows:

20ft by 25ft

Calculating the area of the ceiling

Area = 20ft * 25ft

Area = 500ft^2

So, the area Micky will cover = Area of 4 walls + Area of ceiling

Total Surface Area = 900ft^2 +500ft^2

Total Surface Area = 1400ft^2

Hence, Micky will cover 1400ft²

2+ (-3)^2 - (-1)<br><br> please explain! :3
Ugo [173]

Answer:

12

Step-by-step explanation:

Hello!

First of all you have to understand the order of operations.

PEMDAS

Parenthesis, Exponent, Multiplication/Divison, Addition, Subtraction.

From this you can see that we first have to deal with the exponent, then multiplication, then the addition.

So we get 2+9-(-1)

The 9 is from -3^2

2+9+1

11+1

12.

Hope this helps!
