a) Here is a drawing of a jar with the label "l" representing the number of Lollie's in the jar:
________
| |
| l |
|________|
b) Using symbols, we can represent the information as follows:
Number of Lollie's in the jar = l
Number of Lollie's in the jar of Lollie's plus one = l + 1
We don't know exactly how many Lollie's are in a jar, but we know each jar has the same number. We will refer to this unknown number as l, where l is the pronumeral. a-Draw a jar and label the number of Lollie's in the jar as l. b- There is a jar of Lollie's plus one lolly. Represent this information using pictures and using symbols.

if y represents any number, write terms for expressions for:
a. 5 times that number
b. 2 less than that number
c. 8 more than that number
d. the number divided by 4 (or the quotient of y and 4)
e. the next consecutive number (that is, the counting number after y)
a. 5 times that number
b. 2 less than that number
c. 8 more than that number
d. the number divided by 4 (or the quotient of y and 4)
e. the next consecutive number (that is, the counting number after y)
a. 5 times that number: 5y
b. 2 less than that number: y - 2
c. 8 more than that number: y + 8
d. the number divided by 4 (or the quotient of y and 4): y/4
e. the next consecutive number: y + 1
b. 2 less than that number: y - 2
c. 8 more than that number: y + 8
d. the number divided by 4 (or the quotient of y and 4): y/4
e. the next consecutive number: y + 1
suppose the are d dogs currently at a lost dog home.
a. if three dogs find homes, write an expression to represent the total number of dogs at the dogs home .
b. Just after 3 dogs find homes, the number of dogs at the lost dogs home is doubled. Write the expression to represent the new number of dogs at the last dogs home.
c. The dogs are then sorted into then pens with them same number of dogs in each pen . Write another expression to represent the number of dogs in each pen.
a. if three dogs find homes, write an expression to represent the total number of dogs at the dogs home .
b. Just after 3 dogs find homes, the number of dogs at the lost dogs home is doubled. Write the expression to represent the new number of dogs at the last dogs home.
c. The dogs are then sorted into then pens with them same number of dogs in each pen . Write another expression to represent the number of dogs in each pen.
a. If three dogs find homes, the expression to represent the total number of dogs at the lost dog home would be: d - 3
b. Just after three dogs find homes, the number of dogs at the lost dog home is doubled. The expression to represent the new number of dogs at the lost dog home would be: 2 * (d - 3)
c. The dogs are then sorted into pens with the same number of dogs in each pen. The expression to represent the number of dogs in each pen would be: (2 * (d - 3)) / n, where n represents the number of pens.
b. Just after three dogs find homes, the number of dogs at the lost dog home is doubled. The expression to represent the new number of dogs at the lost dog home would be: 2 * (d - 3)
c. The dogs are then sorted into pens with the same number of dogs in each pen. The expression to represent the number of dogs in each pen would be: (2 * (d - 3)) / n, where n represents the number of pens.

c. it costs an adult extra $1.50 for the same trip. Write an expression for the cost of an adult catching the bus three days per week.
a. If she uses the bus three days a week, she spends 3 * d dollars on bus fares for the week.
b. There are forty school weeks in a year, and she travels three times a week on the bus. The expression for how much it will cost her for the bus fare each year would be: 40 * 3 * d.
c. It costs an adult extra $1.50 for the same trip. The expression for the cost of an adult catching the bus three days per week would be: 3 * (d + 1.50).
b. There are forty school weeks in a year, and she travels three times a week on the bus. The expression for how much it will cost her for the bus fare each year would be: 40 * 3 * d.
c. It costs an adult extra $1.50 for the same trip. The expression for the cost of an adult catching the bus three days per week would be: 3 * (d + 1.50).
if n=3, evaluate the following expressions.
a. n=4
b. 2n
c. 4n-2
a. n=4
b. 2n
c. 4n-2
a. For n = 3, the evaluation of n + 4 would be 3 + 4 = 7.
b. For n = 3, the evaluation of 2n would be 2 * 3 = 6.
c. For n = 3, the evaluation of 4n - 2 would be 4 * 3 - 2 = 10.
b. For n = 3, the evaluation of 2n would be 2 * 3 = 6.
c. For n = 3, the evaluation of 4n - 2 would be 4 * 3 - 2 = 10.
