Question

Three times the sum o a number four is five times the number, decreased by two. If x represents the number, which equation is a correct translation of the statement? 3(x + 4) = 5x - 2 3(x + 4) = 5(x - 2) 3x + 4 = 5x - 2 3x + 4 = 5(x - 2) what is the equation of the line that passes through the point (3, -7) and has a slope of -4/3? y = -4/3x + 3 y = -4/3x - 3 y = 37/3x - 4/3 y = -59/9x - 4/3 The equation P = 0.0089r^2 + 1.1149r + 78.4491 models the United States population, P, in millions since 1900. If t represents the number of years after 1900, then what is the estimated population in 2025 to the nearest tenth of a million? 217.8 219.0 343.9 356.9 Which value of x is the solution of the equation 2(x - 4) + 7 = 3? 1 2 6 0

Let x be a number

according to the question :

Three times the sum f a number (x) and 4 becomes :

= 3( x + 4 )

five times the number (x) decreased by 2 becomes = 5x - 2

So, according to the statement f the question, the equation wil be:

   3( x + 4 ) = 5x - 2 [ Answer ]

Hence, option (1) is the correct answer .
