increased means added to so a certain increased by 4 would be
x + 4
A certain number increased by 4
3x+4 = 28 3x = 28-4 3x = 24 x=8
3x + 4 = 28Subtract 4 from each side:3x = 24Divide each side by 3:x = 8
x - 2 = 7 + x/4 4x - 8 = 28 + x 3x = 36 x = 12
4*(n + 2)
x + 4
x-4=8+x/5 5(x-4)=5(8+x/5) 5x-20=8+x 4x=28 x=7
2*x+(-4) or x+(-4)+(-4) ?
3z+4
Its 11
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.
x/4+7=-31
