Answer:

-0.7 or -\frac{7}{10}

Step-by-step explanation:

-0.75-(-\frac{2}{5})+0.4+(-\frac{3}{4})

The opposite of -\frac{2}{5} is \frac{2}{5}

-0.75 + \frac{2}{5} +0.4 - \frac{3}{4}

Convert decimal number −0.75 to fraction -\frac{75}{100}.

​Reduce the fraction-\frac{75}{100} to lowest terms by extracting and canceling out 25.

-\frac{3}{4} + \frac{2}{5}+0.4-\frac{3}{4}

Least common multiple of 4 and 5 is 20. Convert -\frac{3}{4} and \frac{2}{5} to fractions with denominator 20.

-\frac{15}{20}+ \frac{8}{20} +0.4 - \frac{3}{4}

Since -\frac{15}{20} and \frac{8}{20} have the same denominator, add them by adding their numerators.

\frac{-15 +8}{20} +0.4-\frac{3}{4}

Add -15 and 8 to get -7

-\frac{7}{20}+0.4-\frac{3}{4}

Convert decimal number 0.4 to fraction \frac{4}{10}. Reduce the fraction \frac{4}{10} to lowest terms by extracting and canceling out 2.

-\frac{7}{20}+\frac{2}{5}-\frac{3}{4}

Least common multiple of 20 and 5 is 20. Convert -\frac{7}{20} and \frac{2}{5} to fractions with denominator 20.

-\frac{7}{20}+\frac{8}{20}-\frac{3}{4}

Since -\frac{7}{20} and \frac{8}{20} have the same denominator, add them by adding their numerators.

20-7+8-\frac{3}{4}

Add -7 and 8 to get 1.

\frac{1}{20}-\frac{3}{4}

Least common multiple of 20 and 4 is 20. Convert \frac{1}{20} and \frac{3}{4} to fractions with denominator 20.

\frac{1}{20}-\frac{15}{20}

Since \frac{1}{20} and \frac{15}{20} have the same denominator, subtract them by subtracting their numerators.

\frac{1}{20}-15

Subtract 15 from 1 to get -14.

20-14

Reduce the fraction -\frac{14}{20} to lowest terms by extracting and canceling out 2.

-\frac{7}{10} or -0.7

Hope this helps! Brainliest would be much appreciated! Have a great day! :)

Solve x(x-1) (X-5) <=O​
lara [203]

Answer:

x <= 0 or  1 = < x <= 5.

Step-by-step explanation:

First we find the critical points:

x(x - 1)(x - 5) = 0

gives x = 0, x = 1 and x = 5.

Construct a Table of values:

               <u>  x < 0 </u>  <u>x = 0 </u> 0<u>< x < 1</u>  <u>1 =< x <= 5</u>     <u>x = 5</u>

x                  <0        0          >0             <0           0

x - 1             <0       -1           >0              <0           0

x - 5            < 0       0          > 0             <0           0

x(x-1)(x-5)    < 0      0          >0              <0          0 

So the answers are x =< 0 or  1 =< x <= 5.

Someone please help me !!!
alexandr1967 [171]

Because this triangle is a right traingle and has one angel that is 45 degrees, the third angle must be 45 degrees to because 90+45+45=180. With that, km must be the same length as lm. we know lm is 5 so km is 5 too. No we can plug this into the Pythagorean Theorem too get

5^2+5^2=c^2

25+25=c^2

50=c^2

√50=√c^2

√25*2=c

5√2=c

Thats your answer to the length of lk.
