The sum of the measures of the angles of a triangle is 180 degrees.
Angles STU and STR are supplementary angles.
Angles R and STR are congruent.
m<STU + m<STR = 180
8x + m<STR = 180
m<STR = 180 - 8x
m<R = m<STR = 180 - 8x
m<RST + m<R + m<STR = 180
7x - 54 + 180 - 8x + 180 - 8x = 180
-9x + 360 = 180
-9x = -126
x = 14
2y-7>15
2y> 15+7
2Y > 22
2Y/2>22/2
y > 11
put any number below 11 in the left side it will be less then 15
2x-5> 1
2x > 1 +5
2x > 6
2x/2 > 6/2
x > = 3
put 3 instead of x in the left side it will be equal to the right side or put anything less then 3 then the left side will be less then 1
2x+5>1
2x > 1-5
2x > -4
2x/2>-4/2
x> -2
put -2 instead of x it will be equal to the right side anything less then -2 then it will be less the the right side
$6.75/10 = $.68 per option 1
$7.25/12 = $.60 per option 2
Option 2 is the better buy
Here is you're answer:
In order to find the answer you have to switch all the options into decimals to see which one is equivalent to 2.46!
Therefore you're answer is option C "2 23/50." Remember when wanting to find the decimal divide the numerator by the denominator after you convert the mixed number (if it's a mixed number) into a improper fraction!
Hope this helps!
This is honestly simple but we all need help! The answer is 55,053. Hope this helps! =3
