$6.40
All beads and pendants = $19.20, and the beads equal $12.80, so 12.80 + ? = 19.20. So you would use the equation. 19.20 - 12.80, which equals 6.40.
Sean reads his book by what speed
This answer is quite unorthodox
LIke a speed question. We will find the amount of pages Sean read per hour or minutes if u want to convert
So speed of reading = amount of pages read/ time
= 144/3 hours or 144/3*60 minutes
=48 or 8/10 minutes
So time taken to complete his book at the same pace he is reading
amount of pages to read/speed of reading
=264/48 or 264*10/8
=5.5 hours or 330 minutes
hope u understood
Answer:
Step-by-step explanation:
law of sines
Sin(A) / a = Sin(B)/b
where A = 24
a=BC
B= 59
b =AB
then
Sin(24)/a =Sin(59)/19
0.4067366 / a = 0.8571673 / 19
0.4067366 / a = 0.045114
0.4067366 / 0.045114 = a
9.015 = a
BC = 9.0 mi
(2y + x) + (2y + x) = (-2y + x) + (2x - 15)
2y + x + 2y + x = -2y + x + 2x - 15
4y + 2x = -2y + 3x - 15
+2y + 2y
6y + 2x = 3x - 15
-2x -2x
6y = x - 15
+15 +15
15 + 6y = x
