3x - 3y = 9 and x + 3y = 12 <br> Elimination
Firlakuza [10]

Answer:

x=5.25,y=2.25

Step-by-step explanation:

We can add the two equations to eliminate the variable y and solve for x:

3x-3y+x+3y=9+12

4x=21

x=5.25

Now, we can use substitution to solve for y:

x+3y=12 (given)

5.25+3y=12

3y=12-5.25

=6.75

y=2.25

Hope this helps :)

How many whole numbers are less than 600 but are multiples for both 8 and 11
shutvik [7]

Answer:

6

Step-by-step explanation:

11 = 11*1

8 = 2*4

They have no common factors, so the LCM (least common multiple) is

2*4*11 = 88

The multiples of 8 and 11 below 600 are multiples of 88

88*1 =88

88*2 =176

88*3 =264

88*4 =352

88*5 =440

88*6 =528

This is the last multiple because if we add 88 if would be over 600

Nitella [24]
An annotated bibliography includes the citation and a brief description of the source.

The citation can be made by plugging in information in an online citation website.

The description is 2 to 3 sentences about what type of source (primary or secondary) and how you used it (for the images, background info, etc).

What is the solution to the system of equations? y = x +2 y = 3x -2
Mrrafil [7]

Answer:

x=2 and y= 4

Step-by-step explanation:

y = x +2 ----------(i)

y = 3x -2--------(ii)

Now, comparing (i) and (ii)

x+2= 3x-2

=>x-3x = -2-2

=>-2x= -4

=>2x= 4

=>x= 2

From eq (i)

y= x+2 = 2+2= 4
