Answer:
Step-by-step explanation:
![\frac{2}{3}[(15-6)-8(8+1)]=\frac{2}{3}[9-8*9]\\\\=\frac{2}{3}[9-72]\\\\=\frac{2}{3}*(-63)\\\\=2*(-21)\\= -42](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B3%7D%5B%2815-6%29-8%288%2B1%29%5D%3D%5Cfrac%7B2%7D%7B3%7D%5B9-8%2A9%5D%5C%5C%5C%5C%3D%5Cfrac%7B2%7D%7B3%7D%5B9-72%5D%5C%5C%5C%5C%3D%5Cfrac%7B2%7D%7B3%7D%2A%28-63%29%5C%5C%5C%5C%3D2%2A%28-21%29%5C%5C%3D%20-42)
Answer:
In order to subtract a whole number from a fraction, you first have to turn the hole number into a mixed fraction.
Step-by-step explanation:
Say your fraction was 2/3 and your whole number was 5.
They have to have like denominators
5/1 - 2/3 = 15/3 - 2/3
15/3 - 2/3 = 13/3
13/3 = 4 1/3

Sin x = 7/12
x = arcsin (7/12) = 35.69°
Answer:
The answer to your question is the big dog weighs 120 pounds
Step-by-step explanation:
Data
big dog = b
medium dog = m
small dog = s
Equations
b = 5s
m = 12 + s
s = 2/3 m
Process
1.- Substitute m in the last equation
s = 2/3(12 + s)
s = 24/3 + 2/3s
s - 2/3s = 8
1/3 s = 8
s = 8(3)
s = 24 pounds
2.- Substitute s in the first equation
b = 5(24)
b = 120 pounds
