5 x 7 centimeters = 35 square centimeters
5 x 7 inches = about 226 cm2
5 x 7 feet = 32 516 cm2
5x-2x=9
5x plus 3 does equal 3 plus 5x; commutative law.
If you mean (5x+3)2 = 36... 5x+3 must equal 6 so - 5x has to equal 3 - therefore x = 0.6
100.
3x = 7-5x 8x=7 x = 7/8 x = 0.875
5x - 42x + 5 = - 37 x +5
The base is 3 centimeters wide. The formula is A = 1/2 (base x height) 7.5 = (5x)/2 15 = 5x x = 3
x is less than or equal to negative 3 or x< or =-3
The Question is not in a proper form. Is it 4-1+5x or 4-1-5x? Or most likely 4-1= 5x, where x would equal 3/5.
5x + 6 = 31 5x = 31 - 6 5x = 25 x = 5 So the equation is equal.
5X + 5 = 30 5X = 25 X = 5 =======You are wrong!
