Answer:
17.
Step-by-step explanation:
one dash is equal to 2. so just go by twos
(40 min)/(5 mi) = (time)/(7 mi) . . . . . the rates are the same
(7/5)*(40 min) = time = 56 min
At the same rate, it would take Petra 56 minutes to jog 7 miles.
Answer:
m∠PTQ = 40°
Step-by-step explanation:
From the picture attached,
Two lines PS and RQ are intersecting each other at a point T.
Vertical angles formed at the point of intersection T will be equal in measure.
m∠PTQ = m∠STR and m∠PTR = m∠QTS
Therefore, (x + 28)° = (2x + 16)°
28 - 16 = 2x - x
12 = x
m∠PTQ = (x + 28)°
= 12 + 28
= 40°
Therefore, measure of angle PTQ is 40°.
Answer:
-5x+10x+3=5x+6 Is No solution
Answer:

Step-by-step explanation:
We have the four thickest books from the line plot given by
Two books of
inch thick and the two books of
inch thickness.
So when the two
inch thick book is being piled on the top of a
inch thick books.
Therefore, the total thickness of the pile of books is given by :



Therefore, the thickness of the pile is
.
