Answer:
see explanation
Step-by-step explanation:
let ∠BCE = x then ∠ECD = 5x - 6 and
∠BCE + ∠ECD = ∠BCD, substitute values
x + 5x - 6 = 162, that is
6x - 6 = 162 ( add 6 to both sides )
6x = 168 ( divide both sides by 6 )
x = 28
Hence
∠BCE = x = 28°
∠ECD = 5x - 6 = (5 × 28) - 6 = 140 - 6 = 134°
Answer: the result is 930 minutes.
Step-by-step explanation:
15.5 hours to minutes has been calculated by multiplying 15.5 hours by 60
Answer:
x=4
Step-by-step explanation:
56/14=4
Cross multiply the original proportion
5x = 2y Divide by 2
5x/2 = y Now divide by 5
x/2 = y/ 5
So the answer is y/5
Answer:
2j²/5
Step-by-step explanation:
We know that j has to be squared so j², and to find 2/5's of that number we need to multiply it by 2/5.
j²×(2/5)
Now to simplify it we can multiply the j² to the numerator.
2j²/5
