Question
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 +
=
Let's represent the number of weekdays Lindsay practiced as x.
According to the given information, she practices 50 minutes on Saturday and 30 minutes on most weekdays. In a week, there are 5 weekdays.
Therefore, the total number of minutes Lindsay practiced on weekdays is 30x.
The total number of minutes Lindsay practiced in a week is the sum of the minutes she practiced on weekdays and the minutes she practiced on Saturday, which is 140.
So, the equation in the form px + q = r to represent this problem is:
30x + 50 = 140
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's represent the number of days as x.
According to the given information, the baby elephant weighs 150 pounds when born and gains 2 pounds per day during the first year.
Therefore, the weight of the elephant after x days is given by 150 + 2x.
We want to find the number of days it will take for the elephant to weigh a total of 224 pounds. So we set up the equation:
150 + 2x = 224
To solve for x, we subtract 150 from both sides of the equation:
2x = 224 - 150
2x = 74
Dividing both sides of the equation by 2:
x = 37
Therefore, it will take the elephant 37 days to weigh a total of 224 pounds.

The operations needed to solve this problem are subtraction and addition.
Let's represent the number of stickers Reann started with as x.
According to the given information, she gives her friend half of the stickers, which is x/2.
Then, her brother gives her 8 new stickers.
So, the total number of stickers she has after these two actions is:
x - (x/2) + 8
According to the problem, she ends up with 12 stickers.
Setting up the equation:
x - (x/2) + 8 = 12
To solve for x, we simplify the equation:
2x - x + 16 = 24
x + 16 = 24
Subtracting 16 from both sides of the equation:
x = 8
Therefore, Reann started with 8 stickers. The operations used to solve this problem were subtraction and addition.

According to the problem, she ends up with 12 stickers.
Setting up the equation:
x - (x/2) + 8 = 12
To solve for x, we simplify the equation:
Multiply the whole equation by 2 to remove the fraction:
2x - x + 16 = 24
Combine like terms:
x + 16 = 24
Subtract 16 from both sides of the equation:
x = 8
Therefore, Reann started with 8 stickers. The operations used to solve this problem were subtraction and division.
