number of marks available = 140
percentage secured = 70%
therefore marks secured =

hope helpful~
Unsolvable because there is no factor for 13
The answer of larger angle is 132 degree
30 out of 140
that means the equation is 30/140
that equals .2142 . . .
that moves over the 21%
3x + 4y = 16 Write original equation
3x + 4y - 4y = -4y + 16 Subtract 4y from each side
3x = -4y +16 Simplify
3x/3 = -4y/3 + 16/3 Divide each side by three
x = -4y/3 +16/3 Simplify
I hope this helps!
