Answer:
0.8
Step-by-step explanation:
We begin with the expression: ![0.5+(-\frac{3}{4} )+0.25-(-\frac{4}{5} )](https://tex.z-dn.net/?f=0.5%2B%28-%5Cfrac%7B3%7D%7B4%7D%20%29%2B0.25-%28-%5Cfrac%7B4%7D%7B5%7D%20%29)
First, we need to convert the fractions into decimals to make this easier.
and ![-\frac{4}{5} =-0.8](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B5%7D%20%3D-0.8)
Once we have this, we can simplify it
![0.5-0.75+0.25-(-0.8)\\\\0.5-0.75+0.25+0.8\\\\0.75-0.75+0.8\\\\0.8](https://tex.z-dn.net/?f=0.5-0.75%2B0.25-%28-0.8%29%5C%5C%5C%5C0.5-0.75%2B0.25%2B0.8%5C%5C%5C%5C0.75-0.75%2B0.8%5C%5C%5C%5C0.8)
I'm assuming this is a math question and all the tents equal the same thing, so to find the price for one tent, we would divide 40/3
Each tent is about $13.33
If this is a true or false question, it’s false because 2/10 + 7 ≠ 10. the correct inequality would be 2/10 + 7 = 12.
Well, it would become 5/7x=40.5. Divide both sides by 5/7, so it is 40.5 * by the reciprocal of 5/7 (7/5). The answer is 56.7 pounds.
An interval scale has measurements where the difference between values is meaningful. For example, the year 0 doesn’t imply that time didn’t exist. And similarly, a temperature of zero doesn’t mean that temperature doesn’t exist at that point. Arbitrary zeros (and the inability to calculate ratios because of it) are one reason why the ratio scale — which does have meaningful zeros — is sometimes preferred.
