D=dante's cards number
a=anna's cards number
d=60
this (d) is at least (smallest is, aka greater than or equal to or <u>></u>) 6 more than (+6) 3 times as many as anna (3 times a or 3a)
d<u>></u>6+3a
d=60
60<u>></u>6+3a
subtract 6 from both sides
54<u>></u>3a
divide both sides by 3
18<u>></u>a
anna has at least 18 cards

18 and 36 in share a common denominator of 18. 18 divided on 18 is 1. 36 divided on 18 is 2. so 1/2 is equivalent to 18/36.
1 5/8 equals one whole (8) plus 5. 8 + 5= 13. 13/5 is your answer
19 divided on 5 is 3.8. 3.8 converted to a fraction is 3 and 0.75. 0.75 in fraction form is 4/5. your answer is 19/5 = 3 4/5 or 3 and 8/10.

Answer:
it's in the 10's place so it means 80, so 8 groups of 10
Step-by-step explanation:
X=4
After squaring both sides, you get
4(x+5)=x^2-20x+100
Multiply
4x+20=x^2-20x+100
Collect like terms
4x+20-x^2+20x-100=0
Reorder
24x-80-x^2=0
Change signs & Write as difference. You end up with
x^2-4x-20x+80=0
Factor
x-4=0 , x-20=0
4=4 , 0=20
x=4
