A
Let the number of hours Brian travelled = X
Then the number of hours Anne traveled = 5X + 2
Since they together travelled 20 hours, then
X + ( 5X + 2) = 20
X + 5X + 2 = 20
6X + 2 = 20
6X = 20 - 2
6X = 18
X = 18/6
= 3 hours.
So brian travels for a period of 3 hours.
Now the number of hours Anne travelled = 5X +2
= (5 * 3) + 2
= 15 + 2
= 17 hours.
Answer:
19
Step-by-step explanation:
Adriana needs to send 232 invitations to her family and friends for her party.
There are 12 invitations in a box.
We need to find how many boxes will Adriana needs to order so that everyone receives an invitation. Let there are x boxes. It can be calculated as :
or
x = 19
So, she will need approx 19 boxes.
A ray has only one end point and is infinite at the other end.
the end where the ray is infinite is denoted by an arrow while the end point is denoted by a dot.
based on this and comparing these definitions to the drawing:
the rays in the drawing are PT and ST
