Can someone help me?

Answer:

Option C.

Step-by-step explanation:

we have

Solve for x

That means ---> isolate the variable x

Multiply by 8 both sides to remove the fractions

Multiply by -1 both sides

Remember that

When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

Divide by 5 both sides

Answer:

C

Step-by-step explanation:

Because it just is

{y = x - 4    

                          => 2x+x-4=5 => 3x=9......x=3

{2x + y = 5                                                 y=3-4=-1

________________________________________________

{x+4y=6

{y=-x+3

=> x+4(-x+3)=6

   x-4x+12=6

-3x=-6

x=2

y=-2+3=1

y=1

___________________________________________________-

{x+2y=9

{x-y=3 .......x=3+y

3+y+2y=9

3y=6

y=2

x=3+2=5

x=5

_________________________________

{3x-2y=9

{y=2x-7

3x-2(2x-7)=9

3x-4x+14=9

-x=-5

x=5

y=2*5-7=10-7=3

y=3

Answer:

its 1/6 trust me

What is an expression?

An expression is a combination of numbers, variables, and operators (such as addition, subtraction, multiplication, and division) that represents a mathematical or logical calculation. It can include constants, variables, and functions that can be evaluated to produce a value.

To find out how much lemon-lime drink Mac made, we need to add the volumes of the lemonade and limeade together:

4 liters (lemonade) + 2 liters (limeade) = 6 liters (lemon-lime drink)

Therefore, Mac made 6 liters of lemon-lime drink by mixing 4 liters of lemonade with 2 liters of limeade.
