Simplify 6/10 by dividing both 6 and 10 by 2.
6/2 = 3
10/2 = 5
6/10 = 3/5
Answer:
where is the question
Step-by-step explanation:
It is D because whenever you take away the zero the amount of both numbers would be the same and adding it to the second one would keep it the same. This is a known fact for all decimals the end in zero you can add as many and take away is money but it really only matters as to what the real numbers are they don’t include zero!
Answer:
f = 1
Step-by-step explanation:
Use the method of cross- multiplication
= 
⇒ ad = bc, thus
20f = 5(f + 3) ← distribute
20f = 5f + 15 ( subtract 5f from both sides )
15f = 15 ( divide both sides by 15 )
f = 1
x² + 7x/10 = 1/7
x² + 7x/10 - 1/7 = 0
Δ = b² - 4.a.c
Δ = (7/10)² - 4 . 1 . (-1/7)
Δ = 0,48999999999999994 - 4. 1 . (-1/7)
Δ = 1,0614285714285714
Há 2 raízes reais.
x = (-b +- √Δ)/2a
x' = (-(7/10) + √1,0614285714285714)/2.1
x'' = (-(7/10) - √1,0614285714285714)/2.1
x' = 0,3302565561201596 / 2
x'' = -1,7302565561201595 / 2
x' = 0,1651282780600798
x'' = -0,8651282780600797
Rounding
x' = 0,17
x'' = -0,87
