What is the difference between the fractions? use the number line to find the answer.

one-half minus 1 and one-fifth
a number line going from negative 2 to positive 2 in increments of startfraction 1 over 10 endfraction

The difference is

Step-by-step explanation:

We must find the common denominator of the fractions.

The common denominator of and is ; therefore we have

now it is easy to subtract using the number line: we have to move units to the left in order to get to .

Thus our answer is

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.
