(4x+1)+(5x-4)+E=180, find E

(4x + 1) + (5x + 4) + E = 180.

Simplify: Combine the x values

4x + 5x = 9x.

Now add 4 + 1 = 5.

So far we have; 9x + 5 + E = 180.

180 - 5 = 175.

9x = 175

175/9 = 19.4 repeated. X = 19.4 repeated.

Substitute in the value we have so far.

(4 x 19.4 repeated + 1) + (5 X 19.4 repeated + 4) = 180

So, E must be 0 for this equation to work.

the circumference of a circle is, 10.676 cm.

step-by-step explanation:

the formula for circumference of a circle is given by:

where

c is the circumference of a circle and

d is the diameter of a circle.

given: diameter(d) = 3.4 cm and use

substitute these values in [1] we get;

cm

therefore, the circumference of a circle is, 10.676 cm
