(1) $12\frac{1}{2} -9\frac{1}{4}$

Let us convert mixed fraction into improper fraction.

$$12\frac{1}{2} -9\frac{1}{4}=\frac{25}{2} -\frac{37}{4}$

Make the denominator same.

$$=\frac{25\times2}{2\times2} -\frac{37}{4}$

$$=\frac{50}{4} -\frac{37}{4}$

$$=\frac{13}{4}$

Now convert improper into mixed fraction.

$$12\frac{1}{2} -9\frac{1}{4}=3\frac{1}{4}$

(2) $5\frac{3}{4}-2\frac{5}{12}$

$$5\frac{3}{4}-2\frac{5}{12}=\frac{23}{4}-\frac{29}{12}$

Make the denominator same.

$$=\frac{23\times3}{4\times3}-\frac{29}{12}$

$$=\frac{69}{12}-\frac{29}{12}$

$$=\frac{40}{12}$

$$5\frac{3}{4}-2\frac{5}{12}=3\frac{4}{12}=3\frac{1}{3}$

(3) $7\frac{1}{5}-3\frac{7}{10}$

$$7\frac{1}{5}-3\frac{7}{10}=\frac{36}{5}-\frac{37}{10}$

Make the denominator same.

$$=\frac{36\times2}{5\times2}-\frac{37}{10}$

$$=\frac{72}{10}-\frac{37}{10}$

$$=\frac{35}{10}$

$$7\frac{1}{5}-3\frac{7}{10}=3\frac{5}{10}=3\frac{1}{2}$

(4) $11\frac{2}{3}-8\frac{1}{2}$

$$11\frac{2}{3}-8\frac{1}{2}=\frac{35}{3}-\frac{17}{2}$

$$=\frac{35\times2}{3\times2}-\frac{17\times3}{2\times3}$

$$=\frac{70}{6}-\frac{51}{6}$

$$=\frac{19}{6}$

$$11\frac{2}{3}-8\frac{1}{2}=3\frac{1}{6}$

the sum of the digits in a two-digit number is equal to 5. if the reverse number is multiplied by 3, the result is 1 more than t

Kisachek [45]

Answer:

41

Step-by-step explanation:

Original number xy

x + y = 5

3 (10y + x) -1 = 10x + y

30y + 3x -1 = 10x + y

7x - 29y + 1 = 0

x = 5 - y

7 (5-y) - 29y +1 = 0

35 - 7y - 29y +1 = 0

36 - 36y = 0

36y = 36

y = 1

x = 5-1 = 4

Original number: 41

check: 4+1=5

3 x 14 - 1 = 42 -1 = 41

Please help.How do I find the length of x?

svetlana [45]

Since the area of B is 9 times the area of A, we know that the sides of B are √9= 3 times the length of the sides of A.

That's how.
