total 22 marbles, green and white ones are 5 so 22-5=17 so 17/22 or 17 out of 22
Pretty sure its 13x+1
if you're looking for x, minus the one so it's 13x=-1 and divide. hope it was helpful
Area: 35 inches
Perimeter: 24
Here's how I got my answer:
<u>Area:</u> The formula for the area of a rectangle is 
. So if we plug that in, it would be 
, which is 35.
<u>Perimeter:</u> You can get the perimeter by adding all the sides together, which is 
, which is 24.
Answer:
Heron's formula (sometimes called Hero's formula), named after Hero of Alexandria, gives the area of a triangle when the length of all three sides are known. Unlike other triangle area formulae, there is no need to calculate angles or other distances in the triangle first.
Let the collection of comic books be x.
4 times the number of comic books in her collection = 4x
3( x + 15 ) = 4x - 65
3x + 45 = 4x - 65
45 + 65 = 4x - 3x ( move all the similar variables to one side of the equation )
x = 110
ans : 110
