MECHANICAL ENGINEER
A MECHANICAL ENGINEER REASEARCHES, DEISGNS, TESTS
TOOLS, AND MANUFACTURES MECHANICAL DEVICES.
ENGINEERS DO PRACTICAL DESIGNS AND INVENTIVE WORK
USING THE WAYS OF SCINCE AND MATH TO COME UP WITH
BENEFICIAL SOLUTIONS TO TECHNICAL PROBLEMS. THEY
PRODUCE MACHINES LIKE ELECTRIC GENERATORS, AND
COMBUSTION ENGINES.
4
CHEMIST
CHEMISTS CONDUCT EXPERIMENTS TO SHOW CHEMICAL
MIXTURE AND STUDY CHEMICAL DIFFERENCES WHICH ARE
IN NATURAL SUBSTANCES AND ARTIFICIAL MATERIALS.
THEY ATTEMPT COST ANALYSIS AND PRICING WHEN
CREATING NEW SUBSTANCES, PROCESSES, AND PRODUCTS.
5
SPACE PLANNER
A SPACE PLANNER PROVIDES TECHNICAL SUPPORT ON
PRODUCT ORGANIZATION AND FURNITURE STORE
PLACEMENTS. THEY ASSIGN OR CLASSIFY SPACE
ACCORDING TO STANDARDS AND PROCEDURES. THEY NEED
A GOOD UNDERSTANDING OF MERCHANDISING AND PRODUCT
MANAGEMENT IN A RETAIL ENVIRONMENT. BY
REASEARCHING AND COMPILING DATA FOR VARIOUS
REPORTS THEY ASSIST IN THE PREPARATION OF HIGHLY
TECHNICAL OR COMPLEX REPORTS.

WHAT IS A MULTIPLE STEP EQUATION?
A MULTIPLE STEP EQUATION IS AN EQUATION THAT
NEEDS MORE THAN ONE OPERATION TO SOLVE IT

• 1. MAKE THE LEADING COEFFICIANT BY ITS SELF
• SUBTRACT NINE BY FROM BOTH SIDES OF THE EQUATION.
• 3. SIMPLIFY THE RIGHT SIDE OF THE EQUATION
• 4. MULTIPLY FIVE ON EACH SIDE OF THE EQUATION SO
  THAT YOU GET THE VARIEBLE BY ITSELF ON ONE SIDE
  OF THE EQUATION

EXAMPLE 1
8

1. MAKE THE LEADING COEFFICIANT BY ITS SELF.
2. SUBTRACT 35 FROM BOTH SIDES OF THE EQUATION.
3. DIVIDE 20 ON EACH SIDE OF THE EQUATION, TO MAKE
   h BY ITS SELF.

• MULTIPLY THE THREE ON BOTH SIDES OF THE EQUATION,
  SO THAT THERE IS NO DENOMINATOR.
• ADD THE TWO TO BOTH SIDES OF THE EQUATION SO THAT
  THE d IS BY ITSELF.

WORD PROBLEM
HAWAII BECAME OUR 50TH STATE IN 1959. ITS THE
ONLY STATE THAT IS NOT IN THE NORTH AMERICAN
CONTINENT. THE ENGLISH ALPHABET CONTAINS TWO
MORE THAN TWICE AS MANY LETTERS AS THE HAWIIAN
ALPHABET. HOW MANY LETTERS ARE THERE IN THE
HAWIIAN ALPHABET?

ANSWER...
2x226 2x2-226-2 2x24 x12 CHECK
2x226 2(12)226 24226 2626

• SUBRACT TWO FROM EACH SIDE.
• 2. DIVIDE BY TWO SO THAT x IS BY ITSELF.

WHY ARE MULTIPLE STEP EQUATIONS IMPORTANT?
MULIPLE STEP EQUATIONS ARE IMPORTANT BECAUSE YOU
NEED THE FORMULA TO SOLVE EQUATIONS INCLUDING,
SOLVING RADICAL EQUATIONS, SOLVING RATIONAL
EXPRESSIONS, DIVIDING/ MULTIPLYING/ ADDING/
SUBTRACTING POLYNOMIALS ECT
