Reann has stickers. She gives her friend half, and then her brother gives her 8 new ones. She ends up with 12 stickers. How many did she start with? Identify the operations needed to solve this problem.
To solve this problem, the following operations are needed:
1. Divide the total number of stickers by 2 to find out how many stickers Reann had left after giving half to her friend.
2. Subtract 8 from the result of the first operation, as her brother gave her 8 new stickers.
3. The final result will be the number of stickers Reann initially had.
name the problems she has to use ex: subtraction and multiplication
The operations needed to solve this problem are:
1. Division (divide the total number of stickers by 2)
2. Subtraction (subtract 8 from the result of the division)
r u sure
I apologize for the confusion. The correct operations needed to solve this problem are:
1. Subtraction (subtract half of the stickers given to her friend from the total number of stickers)
2. Addition (add the 8 new stickers given by her brother)
3. The final result will be the number of stickers Reann initially had.
Sam is buying packages with 9 beads each. His mom bought him 63 more beads. Now, he has 153 beads. How many packages did he buy? Use algebra to determine the answer.
Let's assume that Sam bought "x" packages of beads.
Each package has 9 beads, so the total number of beads in "x" packages will be 9x.
His mom bought him 63 more beads, so he now has 9x + 63 beads.
Given that he now has 153 beads, we can set up the equation:
9x + 63 = 153
To find the value of "x," we need to isolate it on one side of the equation.
Subtracting 63 from both sides of the equation, we get:
9x = 153 - 63
9x = 90
To solve for "x," we divide both sides of the equation by 9:
x = 90 / 9
x = 10
Therefore, Sam bought 10 packages of beads.
Triana is on a 120-mile four-day bike ride. On the first day she travels 24 miles. She would like to travel equal amounts over the remaining three days. How far will she travel on each of those three days? Write and solve an equation of the form px+q=r.
Let's assume that Triana will travel "x" miles on each of the remaining three days.
On the first day, she traveled 24 miles.
On the remaining three days, she will travel a total of 3x miles.
The total distance Triana will travel on the entire trip is 120 miles.
We can write the equation as follows:
24 + 3x = 120
To solve the equation, we need to isolate "x" on one side.
Subtracting 24 from both sides, we get:
3x = 120 – 24
3x = 96
To solve for "x," we divide both sides of the equation by 3:
x = 96 / 3
x = 32
Therefore, Triana will travel 32 miles on each of the remaining three days.
