The point r is halfway between the integers on the number line below and represents the number (use the hyphen for negative numbers and write the answer as a decimal, such as -6.4).

number line from negative 10 to positive 10 in increments of 1 is shown. only the whole numbers are labeled. in between the whole numbers, there should be a tick mark. a point labeled r is placed is placed between the 2nd and 3rd tick marks to the left of 0.

Your answer is -2.5

To the left of the 0 means it's negative

If it's between 2 and 3, then it is -2.5

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
