Help plz<br>6(2x - 11) + 15 = 3x + 12

Ket [755]

Answer:

x = 7

Step-by-step explanation:

Lets do the brackets first,

6 × 2x = 12

6 × -11 = -66

------

Calculate the x constant:

12x - 3x = 9x

-------

Then the ones with no x:

-66 + 15 = -51

51 + 12 = 63

-------

Lastly, divide

63 ÷ 9 = 7

-------

Have a good day :)

The following formula relates 3 equantities: force(F),mass(m),and acceleration(a)

weqwewe [10]

We know, Force = mass × acceleration

( i ) :

Given,
Force = 25 units
Mass = 10 units
Acceleration = ?

Solution,

Applying the formula of force,
➡ Force = mass × Acceleration

⏩ 25 = 10 × acceleration

⏩ 25 / 10 =acceleration

⏩ 2.5 units = acceleration

( ii ) :

Given,
Force = 25 units
Acceleration = 5 units
Mass =?

Solution :

Applying formula,
➡ Force = mass × acceleration

⏩ 25 = 5 × mass

⏩ 25 / 5 = mass

⏩ 5 units = mass
