Answer:
1. Jefferson drew a line 9.5 inches long. Brittany drew a line 10 times as long. What is the difference in length between the two lines? 9.5 x 10 = 95
95-9.5 = 85.5
2. A store has a contest to guess the mass of 10,000 peanuts. If a peanut has a mass of about 0.45 gram. What would be a reasonable guess for the mass of 10,000 peanuts? Show or explain your work.
4,500 grams because 0.45*10,000 is 4,500.
4. Isaac bought three packages of nuts. He bought one package of peanuts that weighed 3.07 pounds. He also bought two packages of pecans that weighed 1.46 pounds and 1.5 pounds. Did the peanuts or the pecans weigh more? How much more? Show or explain your work.
The one package of peanuts weigh more than both of the packages of pecans. (Work: 3.07-2.96= 0.11 pounds.) The package of peanuts weigh 0.11 pounds more than the 2 packages of pecans.
The strategy for these is to look at what these problems are telling you.
It says the y-value, so you know that this is a y = equation.
y = what?
y = 2 more than. 4 is two more than 2, right? So saying it's more than is another way of saying "y is 2 + blah blah."
So y = 2 + what? Three times the x-value. What does that mean? 3*X = 3X.
Thus we arrive at the final answer, y = 3x + 2
Answer:
64 cups of lemon juice
Explanation:
First, you can determine with the information provided the amount of cups of lemon needed to prepare sixteen cups of lemonade:
5 cups of lemonade→2 cups of lemon juice
16 cups of lemonade→x
x=(16*2)/5=6.4 cups of lemon juice
Now, you now that for sixteen cups that is the amount in a gallon you need 6.4 cups of lemon juice and you can use a rule of three to determine the amount needed for ten gallons of lemonade:
1 gallon of lemonade→6.4 cups of lemon juice
10 galons of lemonade→x
x=(10*6.4)/1=64 cups of lemon juice
According to this, the answer is that 64 cups of lemon juice are needed to make ten gallons of lemonade.
