Answer:
or ![-\frac{7}{10}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B10%7D)
Step-by-step explanation:
![-0.75-(-\frac{2}{5})+0.4+(-\frac{3}{4})](https://tex.z-dn.net/?f=-0.75-%28-%5Cfrac%7B2%7D%7B5%7D%29%2B0.4%2B%28-%5Cfrac%7B3%7D%7B4%7D%29)
The opposite of
is ![\frac{2}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B5%7D)
![-0.75 + \frac{2}{5} +0.4 - \frac{3}{4}](https://tex.z-dn.net/?f=-0.75%20%2B%20%5Cfrac%7B2%7D%7B5%7D%20%2B0.4%20-%20%5Cfrac%7B3%7D%7B4%7D)
Convert decimal number −0.75 to fraction
.
Reduce the fraction
to lowest terms by extracting and canceling out 25.
![-\frac{3}{4} + \frac{2}{5}+0.4-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B3%7D%7B4%7D%20%2B%20%5Cfrac%7B2%7D%7B5%7D%2B0.4-%5Cfrac%7B3%7D%7B4%7D)
Least common multiple of 4 and 5 is 20. Convert
and
to fractions with denominator 20.
![-\frac{15}{20}+ \frac{8}{20} +0.4 - \frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B15%7D%7B20%7D%2B%20%5Cfrac%7B8%7D%7B20%7D%20%2B0.4%20-%20%5Cfrac%7B3%7D%7B4%7D)
Since
and
have the same denominator, add them by adding their numerators.
![\frac{-15 +8}{20} +0.4-\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B-15%20%2B8%7D%7B20%7D%20%2B0.4-%5Cfrac%7B3%7D%7B4%7D)
Add -15 and 8 to get -7
![-\frac{7}{20}+0.4-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B20%7D%2B0.4-%5Cfrac%7B3%7D%7B4%7D)
Convert decimal number 0.4 to fraction
. Reduce the fraction
to lowest terms by extracting and canceling out 2.
![-\frac{7}{20}+\frac{2}{5}-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B20%7D%2B%5Cfrac%7B2%7D%7B5%7D-%5Cfrac%7B3%7D%7B4%7D)
Least common multiple of 20 and 5 is 20. Convert
and
to fractions with denominator 20.
![-\frac{7}{20}+\frac{8}{20}-\frac{3}{4}](https://tex.z-dn.net/?f=-%5Cfrac%7B7%7D%7B20%7D%2B%5Cfrac%7B8%7D%7B20%7D-%5Cfrac%7B3%7D%7B4%7D)
Since
and
have the same denominator, add them by adding their numerators.
![20-7+8-\frac{3}{4}](https://tex.z-dn.net/?f=20-7%2B8-%5Cfrac%7B3%7D%7B4%7D)
Add -7 and 8 to get 1.
![\frac{1}{20}-\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B20%7D-%5Cfrac%7B3%7D%7B4%7D)
Least common multiple of 20 and 4 is 20. Convert
and
to fractions with denominator 20.
![\frac{1}{20}-\frac{15}{20}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B20%7D-%5Cfrac%7B15%7D%7B20%7D)
Since
and
have the same denominator, subtract them by subtracting their numerators.
![\frac{1}{20}-15](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B20%7D-15)
Subtract 15 from 1 to get -14.
![20-14](https://tex.z-dn.net/?f=20-14)
Reduce the fraction
to lowest terms by extracting and canceling out 2.
or ![-0.7](https://tex.z-dn.net/?f=-0.7)
Hope this helps! Brainliest would be much appreciated! Have a great day! :)
Answer: the answer is (2,-4) if that's not the answer then can u post a full picture of the question
Step-by-step explanation:
Answer:
![\frac{x}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D%3C1%5Ctextrm%7B%20or%20%7D%5Cfrac%7B4x-2%7D%7B2%7D%5Cgeq%2013)
Step-by-step explanation:
From the graph, we can conclude that,
is less than 2 and not including as there is a hollow circle at the mark 2.
Also,
is greater than or equal to 7 including 7 as there is a solid circle at the mark 7
So, the compound inequality will be ![x](https://tex.z-dn.net/?f=x%3C2%5Ctextrm%7B%20or%20%7Dx%5Cgeq%207)
Now, the option that simplifies to the above inequality is the required answer.
Let us check the first option.
![\frac{x}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D%3C1%5Ctextrm%7B%20or%20%7D%5Cfrac%7B4x-2%7D%7B2%7D%5Cgeq%2013)
![\frac{x}{2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B2%7D%3C1%5C%5C%5Cfrac%7Bx%7D%7B2%7D%5Ctimes%202%3C1%5Ctimes%202%5C%5Cx%3C2%5C%5C%5C%5C%5Cfrac%7B4x-2%7D%7B2%7D%5Cgeq%2013%5C%5C%5Cfrac%7B4x-2%7D%7B2%7D%5Ctimes%202%5Cgeq%2013%5Ctimes%202%5C%5C4x-2%5Cgeq%2026%5C%5C4x%5Cgeq%2026%2B2%5C%5C4x%5Cgeq%2028%5C%5Cx%5Cgeq%20%5Cfrac%7B28%7D%7B4%7D%5C%5Cx%5Cgeq%207)
Therefore, option 1 simplifies to the above compound inequality.
So, the correct answer is option 1.
1 and 1/2 is the right one
