15% of x = 21
Set up proportions.
15/100 = 21/x
Cross multiply the numbers (15 by x, 21 by 100).
Divide 2100 by 15x to get x.
2100/15 = 140
X is 140.
Answer: x= 19
Step-by-step explanation:
RS =~ ST presumably reads segment RS is congruent to segment ST, i.e. the same length.
Then the triangle is isosceles, and angle SRT = angle STR. Angle STU = 180-angle STR.
SRT = 3x - 48, STU = 9x, so STR = 180-9x
SRT = STR
3x - 48 = 180 - 9x
3x + 9x = 180 + 48
12x = 228
x = 19

P(8 or 12) = 1/6
P(not 8 or 12 = 5/6
Let the expected points fro one roll be X.
