Solve and graph the following inequality: 3(7x+17) > -19 + 14x
love history [14]

Answer:

Solving the inequality we get: \mathbf{x>-7}

Step-by-step explanation:

We need to solve and graph the inequality 3(7x+17) > -19 + 14x

Solving:

3(7x+17) > -19 + 14x

Step 1: Multiply  3 with terms inside the bracket

21x+51 > -19 + 14x

Step 2:Subtracting 51 on both sides

21x+51-51 > -19 + 14x-51\\21x>14x-70\\

Step 3: Subtract 14x on both sides

21x-14x>+14x-70-14x\\7x>-70

Step 4: Divide both sides by 7

\frac{7x}{7}>\frac{-70}{7}\\x>-10

Solving the inequality we get: \mathbf{x>-7}

The graph is attached in the figure below.

A patio on the scale drawing is 4 cm long. The scale used is 1 cm represents 5.5 feet. How long is
DochEvi [55]

The patio is 22 feet long.

The act of measuring is the practice of comparing a physical quantity with a recognized standard quantity of a like kind. A base unit, sometimes called a fundamental unit, is a unit used to quantify a base amount. A base quantity is a physical quantity that is part of a traditionally selected subset of physical quantities but cannot be stated in terms of the other physical values in the subset.

Given the scale used is 1cm which represents 5.5 feet.

measure of patio on scale drawing is 4cm.

then  it's length is 5.5 × 4 = 22 feet

These measurements pertain to the following: length, mass, time, electric current, temperature, amount of a substance, and luminance. Here are the seven base units' definitions: Distance: meters (m) Metric length is measured in meters.

hence we get the value of the length of the patio as 22 feet.
