Answer:

Step-by-step explanation:

The easiest first step is to remove the brackets. Other things could be done, but they are done just because you can.

4x = 7 + 3*2x - 5*3        Just to show you more, I'll keep going.

4x = 7 + 6x - 15              Combine the minus 15 and 7

4x = 6x + 7 - 15

4x = 6x - 8                     Now add 8 to both sides. It's a toss up of what to do

4x + 8 = 6x - 8 + 8

4x + 8 = 6x                    Subtract 5x from both sides

4x - 4x + 8 = 6x - 4x

8 = 2x                             Divide by 2

x = 4

The steps usually follow this order.

iren [92.7K]
The answer should be 7/8. simply just enlarge all of the fractions
their LCM is 40,
there fore, the question is 30/40, and the choices will be 20/40, 16/40, 25/40 and 35/40, there fore only 35/40 is larger than 30/40, so the answer is 7/8

Marina86 [1]

Answer:

6.6 stone

Step-by-step explanation:

We will use conversions to change kilograms to stones

1 kilogram= 2.2 pounds,

1 stone= 14 pounds

42 kilogram          2.2 lbs           1 stone

---------------       * -------------   * ---------------

                           1 kg                 14 lbs


All the units cancel except stone

Need urgent help in mathematics!! Will mark brainliest!!!!
Marina86 [1]

₆C₃ is a combination.  you can find this setting in the statistics menu of your scientific calculator (i think).

If you don't have a scientific calculator, you can use the following formula:

nCr = \frac{n!}{r!(n - r)!}

₆C₃  = \frac{6!}{3!(6 - 3)!}

       = \frac{6!}{3!(3)!}

       = \frac{6 * 5 * 4 * 3!}{3!(3)!}

       =  \frac{6 * 5 * 4 }{3 * 2}

       = 5 * 4

      = 20
