4.2 x 10 = 42
3x + 12 = 42 3x = 30 x = 10
x = ? 42 = x squared minus x
If that's x^2 + x - 42, that factors to (x + 7)(x - 6)
If y=-42,theny = -42.QED? ? ?============Another answer:THERE it is ===> Y = -42
If you have a number x, then twice that number is 2*x and so the expression means 42 - 2*x
42 x 0.7 = 42 x 7/10 = 294/10 = 29.4
42 x 10 = 420
It starts: 1 x 42 = 42 2 x 42 = 84 3 x 42 = 126 4 x 42 = 168 5 x 42 = 210 6 x 42 = 252 7 x 42 = 294 8 x 42 = 336 9 x 42 = 378 10 x 42 = 420 11 x 42 = 462 12 x 42 = 504 ...
42,84,126,168,210,252,294,336,378,420,462,504lol
4.2/42 x 100 = 10 Therefore, 4.2 is 10 percent of 42.
-7x = -42 7x = 42 x = 6
42 = (4 x 10) + (2 x 1)
Rounded to two decimal places, 10/42 x 100 = 23.81. Therefore, 10 is approximately 23.81 percent of 42.
42 minutes 60 x 7/10 = 6 x 7 = 42
x+(x+1)+(x+2)+(x+3)=42 4x+6=42 4x=36 x=9 answer: 9, 10, 11, and 12
5 is half of 10 so the answer will be half of 420, which is 210.
There are 10 millimetres in one centimetre. Therefore, 4.2 centimetres is equal to 4.2 x 10 = 42 millimetres.
