Choose what you think the expressions below best represent within the context of the word problem. a man traveled a certain number of miles by automobile and then nine times as far by airplane. his total trip was 600 miles in length. how far did he travel by plane? x represents miles by . 9x represents miles by .

240 miles.

Step-by-step explanation:

Let a man travelled  by an automobile=x miels

and a man travelled distance  by an airpalne  was 9 times the distance travelled by an  automobile. Therefore, the expression is .

According to question , total distance travelled in trip is equal to 600 miles .

Therefore , the expression for this

Hence,

implies that x=

Distance travel by an automobile is 60 miles .

therefore ,the man distance travel =.

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.
