To eliminate x, u would multiply second equation by 2
to eliminate y, u would multiply second equation by 3
You can divide 140 by 4 which is 35
so it would be 35 words per minute
and if you want to find out if it works with the 525 word in 15 mintues
you can do 35 ×15 = 525
Answer:
x = 12
Step-by-step explanation:
The 2 given angles form a straight angle and are supplementary, thus
10x - 20 + 6x + 8 = 180
16x - 12 = 180 ( add 12 to both sides )
16x = 192 ( divide both sides by 16 )
x = 12
That is 2268 when u multiply
