Question

The hanger image below represents a balanced equation. Write an equation to represent the image

Answer 1

Answer:

The equation is $7=2+r$

Step-by-step explanation:

we know that

The equation that represent the image is equal to

$(1+1+1+1+1+1+1)=(1+1)+r$

Solve for r

$7=2+r$

$r=7-2$

$r=5\ units$

Answer 2

Answer:

The required equation is 7=2+r and the value of r is 5 units.

Step-by-step explanation:

In the given hanger, the left side of the hanger has 7 boxes in which each box is of one unit.

The sum of left sides is

$1+1+1+1+1+1+1=7$

The sum of left side is 7.

Right side of the hanger has 2 boxes in which each box is of one unit and pentagon of r units. So, the sum of right side is

$1+1+r=2+r$

It is given that the hanger represents a balanced equation. It means the left sides is equal to the right side. So, the required equation is

$7=2+r$

Subtract 2 from both the sides.

$7-2=2+r-2$

$5=r$

Therefore the required equation is 7=2+r and the value of r is 5 units.
