The two numbers are 3 and 18, if the sum of two number is 21 and the second number is six times the first number.

Step-by-step explanation:

The given is,

                  The sum of two numbers is 21

                   The second number is six times the first number

Step:1

          Let, m - First number

                  n - Second number

Step:2

        From given,

                  n - 6m     ( The second number is six times the first number )

        Equation becomes,

                  Sum = m + n

        Where,

                      21 = m + ( 6m )

                       21 = 7m

                       m = 3

        Substitute m value n becomes,

                        n = 6m

                           = (6 × 3)

                      n  = 18

Result:

          The two numbers are 3 and 18, if the sum of two number is 21 and the second number is six times the first number.

It would be 120.

Look at the first column, 40. It’s basically multiplication and you can just use a calculator.

For example, 40 x 1 = 40,
And if you looks the second column, it’s being multiplied by 2. Which would be 40 x 2, you just have to multiply 3 x 40 which is 120.

Sorry for my english

Help solving this I’m don’t understand
ladessa [460]

AB is a chord that passes through the center O, which means the central angles BOC and AOC are supplementary. So

m\angle BOC+m\angle AOC=180^\circ\implies m\angle AOC=180^\circ-55^\circ=125^\circ

Central angles and the arcs they subtend have the same measure, so that

m\widehat{AC}=m\angle AOC=125^\circ

m\widehat{CBA}=m\widehat{BC}+m\widehat{AB}=m\angle BOC+m\angle AOB=55^\circ+180^\circ=235^\circ
