5^-3=0.008
1/2=0.5
0.5*0.008=0.004
5/0.004=1250
The common denominator is 12.
(3*3)/(4*3)=9/12
(1*4)/(3*4)=4/12
A. Two properties are involved. 1) the additive inverse property of addition that says -1 +1 = 0, and 2) the substitution property of equality that says -1+1 can be substituted for 0.
b. The distributive property.
c. The identity property of multiplication.
d. Here, there are three properties involved. 1) the addition property of equality tha says I can add -3 to both sides of the equation; 2) the additive inverse property that says -3+3 = 0; and 3) the identity property of addition that says ( )+0 = ( ).
2x + 50 > = 100 (thats greater then or equal)
2x > = 100 - 50
2x > = 50
x > = 50/2
x > = 25
minimum number is 25
