Answer:

3.3

Step-by-step explanation:

In equations you must remember the important rule of keeping both sides balanced. If you do one operation to one side you must do it to the other, for example if you added 1.1 to the right side you must do it to the left side in order to keep the equation balanced so,

→ 2.2 = z - 1.1

⇒ Add 1.1 to both sides to isolate z

→ 3.3 = z

⇄ We can substitute 3.3 back into the equation to see if we have the right solution, if we get 2.2 on both sides then our solution is correct

→ 2.2 = z - 1.1

⇒ Substitute 3.3 into the equation

→ 2.2 = 3.3 - 1.1

⇒ Simplify

→ 2.2 = 2.2

Our solution of z = 3.3 is correct

What is the answer and work to this problem. 4x+2y=14 2x+y=7

Nimfa-mama [501]

The given system of equation has no solution.

Step-by-step explanation:

step 1 :

The given equations are 4x + 2y = 14 and 2x + y = 7.

step 2 :

Let 4x + 2y = 14 be the first equation.

Let 2x + y = 7 be the second equation.

The solution (x,y) can be determined by solving the two equations, if only the given two equations are different.

step 3 :

In first equation taking 2 out as a common factor on both sides, the equation becomes:

2 (2x + y) = 2 (7)

So, the first equation resembles the second one.

step 4 :

Since both the equations are similar, they cannot be solved to get a solution. Therefore, the system of equation has no solution which is also known as inconsistent.

A campground has cabins that can each hold 28 campers there are 148 campers visiting the campground.how many cabins are full if

Rainbow [258]

For this case, the first thing we must do is define variables.

We have then:

x: number of cabins

y: number of campers

We now write the equation that models the problem:

$y = 28x$
