Plz help me Using subsitution, which value of x makes this equation true? 4/5 - x = 1/5

A) x= 1/3

B) x= 2/5

C) x= 3/5

D) x= 5/2

c

Step-by-step explanation:

4/5- x = 1/5

x = 4/5-1/5

x = 3/5

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
