Algebra+Addition_Subtraction

=Algebra!= Algebra is when you take variables and add thm to a problem. Ex. 2+t=3 T must equal 1 because 2+1=3.

In summary an algebraic equation is an equation that includes one or more variables. The equation uses letters to represent missing numbers that you are suppose to find out by completing the equation.

__Variable__= A quantity that you can change; you can use a letter to represent a number. __Coefficient__= The number that appears before the variable. __Expression__= A mathematical phrase that has variables and operations signs but NO equal sign. __Equation__= A mathematical sentence with an equal sign and an answer.


 * __Hard problem 1 =__**

You and your family are going to a movie. The adult tickets are $9 and the children tickets are $5. Set up an equation if x adults were going and y children were going. 9x + 5y = If 3 adults and 2 children go to the movies, how much will you spend?

You and 7 other friends are going out to lunch at Chilis. You get nachos which cost 5 dollars. You get coke and sprite which cost 1 dollar each. And for desert you and your friends get molten lava cakes which cost 6 dollars each. Set up equatioin if you get x amount of nachos, y amount of drinks and w amount of molten lava cakes. 5x + 1y + 6w= If you get 3 orders of nachos, 7 drinks and 3 molten lava cakes, how much money will you be spending.

 There were two boys. Joe and Bob. Bob didnt have enough money wen he went to the fair to buy a snack .so he borrowed (m)amount of money and then he had enough money to but an ice cream cone.how much money did Joe give Bob so e could get ice cream? //BOB HAD $1.50// $1.50 + M = 2.50 To see what the amount of money you would do the oppisite equasion 2.50 __- 1.50__ 1.00
