x + 4
A certain number increased by 4
2*x+(-4) or x+(-4)+(-4) ?
increased means added to so a certain increased by 4 would be x + 4
x + 4x = 5x, where x ≥ 0
x/4+7=-31
The expression for the quotient of 4 and a number x increased by 6 is (4/x) + 6. To simplify this expression, you would first divide 4 by x to get 4/x, then add 6 to the result. The final expression represents the quotient of 4 and x with an additional 6 added to it.
(x + 4) = 10Subtract 4 from each side of the equation:x = 6
x - 2 = 7 + x/4 4x - 8 = 28 + x 3x = 36 x = 12
To increase a number by 4 percent, multiply the number by 1.04. In this instance, 1100 x 1.04 = 1144Therefore, 1100 increased by 4 percent is equal to 1144.
15 increased by two times a number x
x-4=8+x/5 5(x-4)=5(8+x/5) 5x-20=8+x 4x=28 x=7
x + 12. If the unknown number is represented by x, the expression for a number increased by 12 would be x + 12.
