Half.
the missing number is 10
:)
I belive the answer should be similar
X+2x+5x=180
8x=180
4x=90
x=90/4
x=22,5
the angles are 22,5, 45, 112,5
x+2x+3x=180
6x=180
x=180:6
x=30
the angles are 30,60, 90
Are you sure the ex is correct???
4/7 is not equal to 8/12. It is not equal because if you 4x2= 8 is equal but if you do 7x?= 12 it would be a decimal and you need equal numbers to make it a equivalent fraction. If it was 4/7= 8/14 that would be equivalent.
Hope I helped! : -)
Think of it like this: imagine a frog on some lily pads and if it hops left it gets smaller(negative) and if it hops right it gets bigger(positive) ,(but think of it like numbers) so -14-5 think about the -14 being way down at the left and then you add on the (-5) since the number you are adding is negative it is getting smaller (going farther away from the zero, not closer) so when you add a negative to a negative number you get smaller instead of bigger. Hope that helps
