You said: 12 + 0.5(x + 8) = 40Subtract 12 from each side:0.5 (x + 8) = 28Multiply each side by 2:x + 8 = 56Subtract 8 from each side:x = 48
Let x = the number Equation: 1/4 x + 3 = 8 multiplying the equation by 4 : 4[1/4x + 3] = 8 (4) x + 12 = 32 x= 32-12 x=20 Therefore, the number is 20.
Factors of a numbers are numbers multiplied to get that number e.g. factors of 8 = 1,2,4,8 (1 x 8) (4x2) factors of 12= 1,2,3,4,6,12 (1 x 12) (2 x 6) (3 x 4) hope this helped :*
4 x 3 = 12, 12 - 4 = 8, the answer is 4
12 more than a 1/2 a number (x) is at most (< or = to) 8. Simplify 12+1/2x is < or = to 8
