Answer:
Step-by-step explanation:
Number 5 is L because you have 18 coins but you only want to find the probability of the pennies. So take 3/18 and simplify to 1/6 by dividing both the numerator and the denominator by 3.
Number 6 can be (-6x - 3), just use the distributive property on the original expression.
Step-by-step explanation:
(3+1/4)-(4+2/5)
(13/4)-(22/5)
find common denominator of 20
(65/20)-(88/20)
-23/20
Hope that helps :)
Answer:
-11,3
Step-by-step explanation: using foil (x-2)(X+10)=x^2+8x-20
x^2+8x-20-13=13-13 X^2+8x-33=0 factoring you get (x+11)(x-3)=0 so x+11=0
x-3=0
x=-11,3
