b=60
Step-by-step explanation:
6+4/5b=9/10b
-4/5b -4/5b
6=1/10b
divide both sides by 1/10
b=60
Answer:
and ![r=-\frac{\sqrt{3} }{4}](https://tex.z-dn.net/?f=r%3D-%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B4%7D)
Step-by-step explanation:
when you solve for r in the given equation, you need to apply the square root property, which gives positive and negative answers (both should therefore be considered):
![r^2=\frac{3}{16} \\r=+/-\sqrt{\frac{3}{16}} \\r=+/-\frac{\sqrt{3} }{4}](https://tex.z-dn.net/?f=r%5E2%3D%5Cfrac%7B3%7D%7B16%7D%20%5C%5Cr%3D%2B%2F-%5Csqrt%7B%5Cfrac%7B3%7D%7B16%7D%7D%20%5C%5Cr%3D%2B%2F-%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B4%7D)
then you need to include these two possible solutions:
and ![r=-\frac{\sqrt{3} }{4}](https://tex.z-dn.net/?f=r%3D-%5Cfrac%7B%5Csqrt%7B3%7D%20%7D%7B4%7D)
Answer:
The answer would be A. 1 1/5
Step-by-step explanation:
48/40 = 1 8/40
1 8/40 Simplify to 1 1/5
Hope this helps!
