Answer:
Step-by-step explanation:
Given: Hector saved twice as much money as Sam.
Ted saved $100 more than Hector.
Gina saved $50 less than Ted.
As given, lets assume the amount of money Sam has in saving be "x".
Now, finding saving of each person given.
Writing the algebric expression of each´s saving amount.
we know, Hector saved twice as much money as Sam.
∴ Hector saving= 
Also, Ted saved $100 more than Hector.
∴ Ted´s saving= 
Next finding Gina´s saving
As given, Gina saved $50 less than Ted.
∴ Gina´s saving= 
Opening parenthesis and solving it.
⇒ Gina´s saving= 
Algebric expression of Gina´s saving=
Hints on solving trigonometry problems:
If no diagram is given, draw one yourself.
Mark the right angles in the diagram.
Show the sizes of the other angles and the lengths of any lines that are known
Mark the angles or sides you have to calculate.
Consider whether you need to create right triangles by drawing extra lines. For example, divide an isosceles triangle into two congruent right triangles.
Decide whether you will need Pythagorean theorem, sine, cosine or tangent.
Check that your answer is reasonable. The hypotenuse is the longest side in a right triangle.
How to use the tangent ratio to find missing sides or angles?
Example:
Simply 5. Absolute value is most commonly used to show that even though what is in the brackets is negative [-7] the actual value for practical purposes needed is positive 7.
55/8 and in the decimal form it's 6.875
Area of a triangle is Base x Height divided by 2
Therefore,
10 • 14
---------- = 70 units squared
