Two pairs of statements about Jeff's housing expenditures are given below. How can both pairs of statements be true?

Mathematics
1 answer:
Irina18 [472]3 years ago
5 0

Explanation:

Pair 1 is true if Jeff's monthly income is $600/20% = $3,000.

Pair 2 is true if Jeff's monthly income is $1200/10% = $12,000.

Both pairs can be true if Jeff's monthly income increased by a factor of 4 in the 20 years from 1990 to 2010.

Obviously, Jeff spent more on housing in 2010. (Fortunately for Jeff, that larger expenditure was a smaller fraction of his income.)

Can u guys help me with this problem

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
