Answer:
21+3x
Step-by-step explanation:
multiply the 3 by everything inside the parentheses
Answer:
90 yards in 15 minutes =6 yds/min
90 yards in 9 minutes =10 yds/min
x = current rate
r = rowing rate
r + x = 10
r - x = 6 Adding both equations
2 r = 16
rowing rate = 8 yds/min
x = 2 yds/min (current rate)
Step-by-step explanation:
Answer:
the answer will be True
Step-by-step explanation:
as the points match up to form a prefect straight line
Step-by-step explanation:
Here in the given figure the value of x will be 70° ( being alternative angle )
x = 70°
Now...
y = 60° ( being corresponding angle )
Now...
60° + 70° + z = 180° ( the sum of interior angle of triangle is 180°
z = 180° - 130°
z = 50° ..
All you have to do is divide 75 by .15. To start, you need to get rid of the decimal in .15, so move your decimal two spots to the right to turn .15 into 15. Then you have to move your decimal that is implied to be at the end of 75 over two spots because you moved the decimal in .15 which makes it 7,500. Now you have:
7,500 ÷ 15 = 500 500 is your answer.
