Answer:
After buying additional hair bands, Colleen can own a total of <em>43 hair bands.</em>
Step-by-step explanation:
Solving this problem entails of finding out the total number of hair bands Colleen can own, based on the amount she already owns and how many more she purchases. Start by reading the problem carefully to break down the information provided.
We know that Colleen already owns twenty eight hair bands. This is important to remember to include. The problem also states that she has a total of fifteen dollars and each individual hair band is priced at one dollar.
Because the hair bands are only a dollar, Colleen can purchase an additional fifteen hair bands.
Setting up an equation will help us solve. Here is how we could set up the equation:
(<em>amount of hair bands already owned </em>= 28) + (<em>number hair bands bought </em>= 15) = (<em>total number of hair bands owned </em>= x)
28 + 15 = x
The equation is now in place. Solve by adding both terms. This is how you will reach the answer.
28 + 15 = x
43 = x
This means that Colleen will have <em>43 hair bands </em>in total, after purchasing fifteen hair bands.
4y + 5+ 3y
The coefficients would be 4 and 3 because they have a variable after them and the constant would be 5.
Answer:
800 pounds.
Step-by-step explanation:
We have been given that an object that weighs 24 pounds on Mercury weighs approximately 80 pounds on Earth. A rock weighs 240 pounds on Mercury. We are asked to find the weight of rock on Earth.
We will use proportions to solve our given problem as proportions state that the ratio between two proportional quantities is equal.
Upon substituting our given value, we will get:
Therefore, the weight of rock on Earth would be approximately 800 pounds.
