Algebra Help!!!?

Using the addition property of equality solve each equation. Be sure to check your answers.





1. y - 3 = -17


2. -5 + y = -19


3. r + (3/5) = -( 7/10 )


4. x + 10.6 = -9


5. 13 - 3r + 2 + 6r - 2r - 2r - 1 = 3 + 2*8


6. 4r - 3 = 5 + 3r








--------------------------------------...





Solve each equation. Be sure to check your answers.





1. 6x = 18


2. -6r = 3


3. (-5/8) x = -25


4. 12 - 18 = 12y - 6y - 3y


5. 8r = 3r - 10


6. (3/4)x - (2/3) = (7/12)





--------------------------------------...





Solve each equation. Be sure to check your answers.





1. 2x - 8x + 35 = 5 - 3x


2. 2 ( x + 2 ) = -4x - 2


3. 7 ( 3m - 2) + 5 = 6 ( 2m - 1) + 24


4. -2 ( x - 4) - ( 3x - 2) = -2 - (6x - 2)


5. 17.3 - 2.7x = 10.55





--------------------------------------...





The equation 4x + 6 = 2 (x+3) + 2x is satisfied regardless of what real number is substituted for x. Substitute a few real numbers and then try solving the equation. Describe what happens.

What is 16% of 90?





--------------------------------------...





Put the following equation in terms of y. (For instance y+x = 2 converts to y = 2-x). Substitute the value for x into the equation to solve for y:





1. 2x + 6y = -12; x = -2


2. 2x - 5y = -10; x = 0





--------------------------------------...





Determine whether each number is a solution of the given equality.


1. x %26lt; -6 a. 6 b. -13 c. -6.7


2. -4x + 3 %26gt;= 23 a. -5 b. 0 c. -9





--------------------------------------...





Describe the graph using set-builder notation





%26lt;*************************************...


-10 -9 -8 -7 -6 -5 -4 -3 -2








--------------------------------------...





Use the multiplication properties of inequality to solve the following problems. Graph the solution sets.





1. -7x %26gt; 21


2. -7x %26lt; -21





--------------------------------------...





Use the multiplication and addition properties to solve the following problems. Graph the solution sets.





1. 4 ( 2y - 1) %26gt; 12





--------------------------------------...





The product of 8 and a number, decreased by 14, is 218. Find the number.

Given that my number is greater than 16 and less than 19. Given that your number is greater than 12 and less than 20. Therefore, our numbers could be the same. Is this a valid or invalid statement?





--------------------------------------...





Solve for x: (-3/8) = (6/x)





--------------------------------------...





Which one of the following is true?


a. A statement that two proportions are equal is called a ratio.


b. The ratio of 1.25 to 2 is equal to the ratio 5:8.


c. The ratio of a 12-inch plant to a 4-foot plant is 3:1.


d. If 30 people out of 70 are men, then the ratio of women to men is 40:100.
