Step-by-step explanation:

Semi monthly salary is: $2770.22/2 = $1385.11

- Semi-monthly payment for Social Security is: $1385.11 x 6.2% = $85.88

=> 7-month payment for Social Security is: $85.88 x 14 = $1,202.32

- Semi-monthly payment for Medicare is: $1385.11 x 1.45% = $20.08

=> 7-month payment for Medicare is: $20.08 x 14 = $281.12

- 7-month expenses are: $1,200 x 7 = $8,400

- 7-month payment for State taxes is: $52 x 14 =$728

- 7-month payment for Federal taxes is: $101 x 14 =$1,414

=> Total expenditure in 7 months: 1,202.32 + 281.12 + 8,400 + 728 + 1,414 = $12,025.44

Total salary in 7 months: $2770.22 x 7 = $19,391.54

=> Total saving in 7 months: 19,391.54 - 12,025.44 = $7,366.1

=> ENough to visit SPain in August

Which expression is equivalent to StartFraction 2 a + 1 Over 10 a minus 5 Endfraction divided by StartFraction 10 a Over 4 a squ

dimaraw [331]

For this case we must simplify the following expression:

$\frac {\frac {2a + 1} {10a-5}} {\frac {10a} {4a ^ 2-1}} =$

We apply double C:

$\frac {(4a ^ 2-1) (2a + 1)} {10a (10a-5)} =$

We apply distributive property in the numerator and we take common factor 5 in the denominator:

$\frac {8a ^ 3 + 4a ^ 2-2a-1} {10a (5 (2a-1))} =$

We factor the numerator:

$\frac {(2a + 1) ^ 2 (2a-1)} {10a (5 (2a-1))} =\\\frac {(2a + 1) ^ 2 (2a-1)} {50a (2a-1)} =$

We simplify:

$\frac {(2a + 1) ^ 2} {50a}$

Answer:

$\frac {(2a + 1) ^ 2} {50a}$
