Given :
Xinran walks 3 mi/h uphill, 4 mi/h on flat land and 5 mi/h downhill.
To Find :
If he walks one mile uphill, then one mile on flat land and then returns by the same route to his starting point, how many minutes does he walk.
Solution :
Time taken to walk one mile uphill is :
Time taken to walk two mile on flat land( one on going and one or returning ) is :
Time taken to walk one mile downhill is :
Total time taken :
Therefore, time taken un 62 minutes.
51÷2=25.5 31÷2=15.5. 25.5× 15.5= 395.25
you just have to multiply
Answer:
The answer is y= −6
Step-by-step explanation:
Let's solve your equation step-by-step.
10−5y=2(14−y)
Step 1: Simplify both sides of the equation.
10−5y=2(14−y)
10+−5y=(2)(14)+(2)(−y)(Distribute)
10+−5y=28+−2y
−5y+10=−2y+28
Step 2: Add 2y to both sides.
−5y+10+2y=−2y+28+2y
−3y+10=28
Step 3: Subtract 10 from both sides.
−3y+10−10=28−10
−3y=18
Step 4: Divide both sides by -3.
−3y/−3=18/−3
y=−6
Answer:
y=−6
Answer:
missing side is 5x - 4
Step-by-step explanation:
x - 1 + ( 3x + 6 ) + third side = 9x + 1
x - 1 + 3x + 6 + third side = 9x + 1
4x + 5 + third side = 9x + 1
third side = 9x + 1 - ( 4x + 5 )
third side = 9x + 1 - 4x - 5
third side = 5x - 4
Answer:
4).
Step-by-step explanation:
sin A = cos B
Because sin A = CB/AB and cos B = CB/AB.
