Sure! Let me help you on this one, Adrien.
There are 18 marbles in the bag, 3 of them being blue. Let's put this in a ratio.
3 out of 18.
Simplify.
1 out of 6.
This means that statistically speaking, if you pull out 6 marbles, one of them will be blue.
P.S. If this answer helped you, please, make sure to say "Thanks" just below my answer. It will help me a lot.
The perimeter is just the sum of all its sides, in this case, 14+8+14+8 is the perimeter of that one.
now, it gets enlarged with a scale factor of 10, namely it gets blown up 10 times, so the length and the width get blown up that much, thus 10*8 and 10*14.
the new perimeter is then (10*8) + (10*14)+(10*8) + (10*14).
Like terms would be 4y and -7y
Or 8 and 2 I believe
Y = 3x + 4
y = -x - 4
3x + 4 = -x - 4
3x + x = -4 - 4
4x = -8
x = -8/4
x = -2
y = 3x + 4
y = 3(-2) + 4
y = -6 + 4
y = -2
solution is (-2,-2) <==
