10/12 = 2*5 / 2*6 = 5/6
15/18 = 3*5 /3*6 = 5/6
25/30 = 5*5 /5*6 = 5/6

But what's the 13/14 :(. You can't simplify it to 5/6 or something else.

10/12=5/6 (Divide numerator and denominator by 2)

13/14=13/14 (Not equivalent to the ratio 5/6)

15/18=5/6 (Divide numerator and denominator by 3)

25/30=5/6 (Divide numerator and denominator by 5)

18 – 12 + x = 10 What value of x makes the equation true? * explanation plz

Kay [80]

Answer:

x = 4

Step-by-step explanation:

Solve for x:

x - 12 + 18 = 10

Hint: | Group like terms in x - 12 + 18.

Grouping like terms, x - 12 + 18 = x + (18 - 12):

x + (18 - 12) = 10

Hint: | Evaluate 18 - 12.

18 - 12 = 6:

x + 6 = 10

Hint: | Isolate terms with x to the left hand side.

Subtract 6 from both sides:

x + (6 - 6) = 10 - 6

Hint: | Look for the difference of two identical terms.

6 - 6 = 0:

x = 10 - 6

Hint: | Evaluate 10 - 6.

10 - 6 = 4:

Answer: x = 4

Two kids are roller skating. Amy, with a mass of 55 kg, is traveling forward at 3 m/s. Jenny, who

alekssr [168]

Answer:

They traveling at $0.37\ m/s$ in backward direction.

Step-by-step explanation:

Given mass of Ammy $m_1=55kg$

and velocity is forward at $v_1=3m/s$

Also, mass of Jenny $m_2=40kg$

Who is travelling in opposite direction $v_2=-5m/s$

Let velocity in forward direction is positive and velocity in backward direction is negative.

Also, velocity after crash is $v$

As they crashed into each other and they moved as one mass. We can apply principle of conservation of momentum.

Conservation of momentum says momentum before collision should equal to momentum after collision.

$m_1v_1+m_2v_2=(m_1+m_2)v$

$(55\times3)+(40\times(-5))=(55+40)v\\\\165-200=95v\\\\-35=95v\\\\v=\frac{-35}{95}=-0.368m/s$

So, velocity after collision $v$ ≅ $-0.37m/s$ is in opposite direction. That is the direction of Jenny.
