Answer:

Step-by-step explanation:

I wrote an excel macro that listed all of the combinations of these 6 numbers in a string, with the x and = symbols mixed in every possible way. (The first combination was “1*2=4568” and the last one was “8654=2*1”) I then had the macro evaluate the equations and find the ones that evaluated to true. Out of the 18,000 combinations of numbers and math symbols, only 8 of them evaluated to true. The true combinations are…………..

416=52*8

416=8*52

512=64*8

512=8*64

52*8=416

64*8=512

8*52=416

8*64=512

(Note that there are only 2 distinct combinations that work. The macro found all the ways that you can express those 2.)

Please help me solve for x
kkurt [141]

\qquad \qquad\huge \underline{\boxed{\sf Answer}}

The shown pair of angles are Co interior angle pair, therefore the sum of those angles is 180°

\qquad \sf  \dashrightarrow \: 130 \degree + 7x + 1 \degree = 180 \degree

\qquad \sf  \dashrightarrow \: 131 \degree + 7x = 180 \degree

\qquad \sf  \dashrightarrow \:  7x= 180 \degree - 131 \degree

\qquad \sf  \dashrightarrow \:  7x= 49 \degree

\qquad \sf  \dashrightarrow \:  x=49 \degree \div 7

\qquad \sf  \dashrightarrow \:  x=7 \degree

The required value of x is 7°
