Answer:

The first blank would be x=6

the other blank would be 9=4.5

Step-by-step explanation:

if you look at the table, you can see that when you insert a number as x (A.K.A the number "two") the number is divided by 2, so in the y row, its half the number that x was.

2÷1=1

4÷2=2

6÷2=3

7÷2=3.5

9÷2=4.5

Hope this helps!

What is/are the solution(s) of the system of equations? Why you say that is the solution? Write your answer in complete sentence

Alexus [3.1K]

Answer: The answer to a system of equations is the point(s) of intersection of the equation involved.

When you have more than one equation with more than one variable, you have a system of equation. The solution(s) is the set of values for each variable that satisfy the equations. This means that the inputting values make the equations true.

One antifreeze solution is 20% alcohol. Another antifreeze solution is 12% alcohol. How many liters of each solution should be c

katrin [286]

Use this systems of equations to solve:

x = first antifreeze
y = second antifreeze

$\left \{ {{.2x + .12y = .18(15)} \atop {x + y = 15}} \right.$

Isolate y.

x + y = 15
Subtract x from both sides.
y = -x + 15

Substitute y into the other equation.

.2x + .12(-x + 15) = .18(15)
Simplify.
.2x - .12x + 1.8 = 2.7
Subtract 1.8 from both sides.
.08x = .9
Divide both sides by .08
x = 11.25

Substitute x in the equation that we isolated y in.

y = -11.25 + 15
y = 3.75

11.25 L of the first antifreeze and 3.75 L of the second.
