−0.35x−0.52=1.93
negative 0.35 x minus 0.52 equals 1.93
The equation that has a solution different from the rest is: negative 0.35 x minus 0.52 equals 1.93.
Lindsay practices the guitar 50 minutes on Saturday and 30 minutes on most weekdays. Last week she practiced 140 minutes. How many weekdays did she practice? Write an equation in the form px+q=r to represent this problem.(2 points)
x +
=
x + (30 * d) = 140
Where x represents the number of weekdays she practiced and d represents the number of weekdays in a week.
A baby elephant weighs 150 pounds when born. It gains 2 pounds per day during the first year. How many days will it take the elephant to weigh a total of 224 pounds?(1 point)
days
Let d represent the number of days it takes for the elephant to weigh a total of 224 pounds.
The elephant gains 2 pounds per day, so the weight after d days can be represented by the equation: 150 + 2d = 224.
To solve for d, we can subtract 150 from both sides of the equation:
2d = 224 - 150
2d = 74
Finally, we divide both sides by 2 to solve for d:
d = 74/2
d = 37
Therefore, it will take the elephant 37 days to weigh a total of 224 pounds.
