Answer:

x = 9

Step-by-step explanation:

Step 1: Write equation

4(x - 2) = 3x + 1

Step 2: Solve for <em>x</em>

<u>Distribute 4:</u> 4x - 8 = 3x + 1
<u>Subtract 3x on both sides:</u> x - 8 = 1
<u>Add 8 to both sides:</u> x = 9

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

<u>Substitute:</u> 4(9 - 2) = 3(9) + 1
<u>Parenthesis (add):</u> 4(7) = 3(9) + 1
<u>Multiply:</u> 28 = 27 + 1
<u>Add:</u> 28 = 28

Answer:

Step-by-step explanation:

Slope = (-1-3)/(6+2) = -4/8 = -1/2

Equation of a line is

y-y1 = m(x-x1)

y-3 = (-1/2)(x+2)

y = 3 + (-1/2)(x+2)

<u>Area of a Rectangle</u>

Given a rectangle of width W and length L, its area is calculated by the formula:

A = W.L

We are given three rectangle-shaped figures and are required to find different measures as explained below.

1. Length L=94 ft, Area = 4,700 square ft

We'll find the width by solving for W:

$\displaystyle W = \frac{A}{L}$

$\displaystyle W = \frac{4,700}{94}$

W = 50 ft

2. A=8,250 square m, W=75 m

We'll find the length by solving for L:

$\displaystyle L = \frac{A}{W}$

$\displaystyle L = \frac{8,250}{75}$

L = 110 m

3. A=1,586 square m, W=26 m

We'll find the length by solving for L:

$\displaystyle L = \frac{A}{W}$

$\displaystyle L = \frac{1,586}{26}$

L = 61 m

A tree measured 25 1/2 feet tall. Over the next 7 1/2 years, it grew to be 63 feet tall. During the 7 1/2 years, what was the av

ANEK [815]

<h2>Greetings!</h2>

Answer:

5feet per year

Step-by-step explanation:

We need to find the distance it grew in that 7 1/2 years:

63 - 25 1/2 = 37 1/2

Now to find the average yearly growth we can divide this by 7 1/2:

37.5 ÷ 7.5 = 5

So the yearly rate of growth of the tree is 5f/y
