a) 4x+13y=40 b) 4x+3y=-40c) multiply b per(-1)=-4x-3y-40d) sum a and c: 4x+13y-4x-3y=40-(-40)=>10y=80 => y=8to find x replace y per its value in a or b and get x=-16
If 10% of t = 40, then t = 400 If s = 16% of 400, then s = 64
50 percent of 80 equals 40.
80 percent of 40 questions equals 32 questions.
40 percent and no other percentage.
40 = 30x x equals 4/3 STEP BY STEP: 40=30x Step 1: Flip the equation. 30x=40 Step 2: Divide both sides by 30. 30x/30 = 40/30 x=4/3 which is in decimal : 1.3(3forever)
