Use the following steps as a guide to solve the following equation. 3x -4 = 2(5x + 5)

Steps

Step 1. Distributive Property

Step 2. Move variables to one side of the equation:

(Addition/Subtraction Property of Equalities)

Step 3. Move constant to the other side of equation:

(Addition/Subtraction Property of Equalities)

Step 4. Isolate your variable:

(Multiplication/Division Property of Equalities)

x = -2

Step-by-step explanation:

1. Distribute the 2: (2 * 5x) + (2 * 5)

3x - 4 = 10x + 10

2. Subtract 3x from both sides

-4 = 7x + 10

3. Subtract 10 from both sides

-14 = 7x

4. Divide both sides by 7

-2 = x

or

x = -2

it is 570

step-by-step explanation:

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
