Mathematics 1


Translate each statement into symbols. Let X represents the unknown number if needed.

$11.      6</-10/

$12.      /8/=/-8/

$13.       Is an irrational number.

$14.      /-6/</-8/

Simplify

$15.      ½ +1 1/3 = 1/2+4/3=(3+8)/6

=11/6=1 5/6

$16.      -7+(-3)= -7-3=-10

$17.      -5+4=-1

$18.      (-4)(-3)=-4-3=12

$19.      (-2)(3)(0)(-4)=0 any number multiplied by zero is zero.

$110.  -1/3(-1/6)= 1/36/1=2

$111.  -12-(-10)= -12+10= -2

$112.  -2-(7-9)=

-2-(-2) =-2+2=-0

$113.  = 7/4.4=1.59

 

$114.  2-22 +3-8

2-4+3-8=2-7-8=

2-15=-13

$115.  = -24-9/11

-33/11=-3


 Evaluate each expression for the values given

$116.  X+2y (x=-2, y=-4)

-2+2(-4) =-2-8

-2-8=-10

=-42-3(4)

=16-12=4

$118.  X2-y2 (x=-2, y=3)

-22 -32 =4+9

=13


 Name the property illustrated.

$119.  0+3=3…………….addition of zero

$120.  6 =………………….simplification

$121.  Opposite of - is ½

$122.  Reciprocal of -   is -0.5

$123.  1 -2+ 2

  1. 1 + 2= =2
  2. 2 -2=

Total gain was ¼

$124.  The approximate net income for February was 2500 dollars.
