Round the following numbers to 2 decimal places 0.273
1.595
6.473
2.571
0.425
44.5564
82.3643
325.1741

Answers

Before I give you the answers, there is a simple rule to observe when rounding a number to two decimal places. If the number in the third decimal place is less than five, then the number in the second decimal place stays the same. If the number in the third decimal place is five or greater than five, the number in the second decimal place is incremented by one. In our case the above numbers are rounded up as follows:

0.273 is rounded up to 0.27
1.595 is rounded up to 1.60
6.473 is rounded up to 6.47
2.571 is rounded up to 2.57
0.425 is rounded up to 0.43
44.5564 is rounded up to 44.56
82.3643 is rounded up to 82.36
325.1741 is rounded up to 325.17

It is asking me to insert parentasies

Answers

If you mean for factoring, then you must take the common factor (term) out of the equation then have the rest out of what you divided

Parenthesis is () so if they said to put () it means to put those on a certain equation or numbers.
Like: 4+5-7 put with parenthesis it is (4+5) -7 or 4+ (5-7)
It's mostly in PEMDAS (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction) problems and algebra equations!

- 3x + 2 – 5x - 7 = 4x + 2

Answers

Answer:

x = -7/12

Step-by-step explanation:

- 3x + 2 - 5x - 7 = 4x + 2

- 8x - 5 = 4x + 2

- 8x - 4x = 2 + 5

- 12x = 7

x = 7/-12

x = -7/12
