To solve for the x, distribute first the numerical coefficients to the terms on the parentheses. This becomes,
7x - 21 = 4x + 20
Transpose all the terms with x and the constant on either sides of the equation,
7x - 4x = 20 + 21
3x = 41 ; x = 41 / 3
Thus, the answer is x = 41/3 which is fourth among the choices.
The probability would be 50 percent because there are 3 gold watches and 3 silver watches.
The total cost will be $9250 to transport 14 tons of sugar.
Step-by-step explanation:
Given,
Cost to rent trucks = $7500
Cost per ton = $125
C = Total cost in dollars
S = Amount of sugar in tons
Total cost = Rent of trucks + Cost per ton * sugar in tons

The equation
relates C to S.
Total cost for 14 tons.
S = 14
Putting in equation;

The total cost will be $9250 to transport 14 tons of sugar.
