Answer:

5x + y = 26

Step-by-step explanation:

Step 1: Distribute

y - 1 = -5x + 25

Step 2: Add 1 to both sides

y = -5x + 26

Step 3: Move 5 to the other side

5x + y = 26

What is the equation of the coordinate A and B if they are (4,7), (6,3) respectively. What is the equation of the straight line.

Nesterboy [21]

Answer: y+2x=15

Step-by-step explanation:

Given

Two points A and B are (4,7) and (6,3) respectively

Using two-point form

$\Rightarrow \dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}$

Putting values

$\Rightarrow \dfrac{y-7}{x-4}=\dfrac{3-7}{6-4}\\\\\Rightarrow \dfrac{y-7}{x-4}=\dfrac{-4}{2}=-2\\\\\Rightarrow y-7=-2x+8\\\\\Rightarrow y+2x=15$

Simplify 2(x+3)-4 showing each step

Alex

To simplify this, we first need to distribute the 2 into the parenthesis.

= 2 * x + 2 * 3 - 4

Now, we can simplify:

= 2x + 6 - 4
= 2x + 2

Hope this helps!

A scale model of a building is 3 inches tall. If the building is 90 feet tall, find the scale of the model.

olganol [36]

The scale model of a building 3 inches tall if the building is 90 feet tall is 2:5

<h3>Scaling of measurement</h3>

Scaling is the way of enlarging or reducing the image of an object.

Given scale model of a building is 3 inches, if the building is 90feet tall, to write the scale;

Convert both measures to same units

Since 1 feet. = 12 in

90 feet = 90/12 in = 7.5 in

Take the ratio

3 : 7.5 = 30: 75

Reduce to lowest term

30: 75 = 2 : 5

Hence the scale model of a building 3 inches tall if the building is 90 feet tall is 2:5

Refer to this sketch of a warehouse please answer please and thank you

stiv31 [10]

Answer:

2) 12,000 ft²

3) 30 gallons.

Step-by-step explanation:

2) 1. You can calculate the lateral surface area of the exterior walls of the warehouse by applying the formula shown below:

$LA=h(2l+2w)$

Where h is the height, l is the lenght and w is the width.

2. Substitute values and you obtain that the lateral area is:

$LA=20ft[(2*200ft)+(2*100ft)]$

$LA=12,000ft^{2}$

3) You know that 1 gallon of paint covers 400 ft², therefore for 12,000 ft² are needed the following number of gallons (which is represented by x):

$x=\frac{(1gallon)(12,000ft^{2})}{400ft^{2}}=30gallons$
