Answer:
(n + 20)/8
Step-by-step explanation:
a sum of a number and 20 is n+20, then you have to divide by 8
Answer:
∠H = 120°
Step-by-step explanation:
In a parallelogram, adjacent angles are supplementary:
∠H +∠T = 180
(2x +60) + (x +30) = 180
3x = 90 . . . . . . . subtract 90, collect terms
x = 30 . . . . . . . . divide by the coefficient of x
Then the measure of angle H is ...
∠H = 2·30 +60 = 120 . . . . . degrees
Answer:
2/2 + 1/2
Step-by-step explanation:
1 1/2 = 3 / 2
possible fractions = 2/2 + 1/2
Answer:
211 feet
Step-by-step explanation:
Consider vertical number line, where 0 is at surface of the lake, positive direction - above the lake surface and negative direction - below the surface of the lake.
A rock is thrown into a lake from a bridge 133 feet above the lake's surface, then initial position of the ball was +133.
The rock sinks 78 feet below the lake's surface, then the final rock's position is -78.
Difference: +133 - (-78) = 133 + 78 = 211 feet
11 hours = 3
1 = 3 hours 40 minutes
