The furniture store sells each chair (c) for $225. To have them shipped to their house, the store charges $60. If the Browns bought c number of chairs, how much did they spend (s)?
==========================================================
Explanation:
1 chair = 225 dollars
c chairs = 225c dollars .... multiply both sides by c
This shows that buying c chairs costs 225c dollars
c is a placeholder for a positive whole number
Add on the $60 shipping cost to get the total cost 225c+60
Therefore s = 225c+60

Find the value of p. p − 1 = 5 p + 3p − 8
Answer:
p = 1
Step-by-step explanation:
[add like terms]
p - 1 = 8 p - 8
[add 8 to both sides]
p + 7 = 8 p
[subtract p from both sides]
7 = 7 p
[divide each side by 7]
p = 1
Answer:
P=1
Step-by-step explanation:
collecting like terms we have
p - 5p - 3p = -8 + 1
-7p = -7
divide both sides by -7
p = 1
Use the relation 2x+y=10 to find the missing values.
Answer:
x= 5 -y/2
y=10-2x
Step-by-step explanation:
solve for Y solve for X
2x + y= 10 2x+ y=10 subtract y from each side
-2x -2x -y=10 -y
y=10-2x 2x=10 -y
2x/2= 10 -y/2 multiply both sides by 2
x= 5 - y/2
use a proportion to find the missing side length in the following similar figures.
a. x= 4.5cm
b. x= 18cm
c. x= 8m
d. x= 2.25cm

this
is
the answer
7, 10, 11, 12, 13, 14, 17 are the 7 numbers that have a range of 10 and a mean of 12.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The range of a list of numbers is the difference between the largest and smallest values of that list of numbers.
The mean is the sum of the observations to the total number of observations.
The seven numbers are 7, 10, 11, 12, 13, 14, 17
Range =17-7=10
Mean=7+10+11+12+13+14+17/7
=84/7
=12
Hence, 7, 10, 11, 12, 13, 14, 17 are the 7 numbers that have a range of 10 and a mean of 12.

Step-by-step explanation:
The cost to rent a rug-cleaning machine from the supermarket is $23 per day. The supermarket charges a check-out fee of $45 for the rental. Tristanne spent $137 to rent the rug-cleaning machine. If d represents the number of days Tristanne rents the machine, which equation can be used to find the value of d?
23 d = 137
23 d + 45 = 137
45 d = 137
45 d + 23 = 137
Answer:
23d + 45 = 137
Explanation:
Since it is $23 per day, that dollar amount must be associated with a variable that multiples it per day that it is rented. Finally, you need to add the one time $45. This equation can then be used to find how many days it was rented for.
23d + 45 = 137
23d = 92 (Subtract 45 from both sides)
d = 4 (Divide by 23 on both sides)
The rug-cleaning machine was rented for 4 days. You found this using the equation: 23d + 45 = 137

During a promotional weekend, a state fair gives a free admission to every 179th person that enters the fair. On Saturday, there were 8,633 people attending the fair. On Sunday, there were 7,400 people attending the fair. How many people received a free admission over the two days?
Answer:
89
Step-by-step explanation:
Given that,
During a promotional weekend, a state fair gives a free admission to every 179th person that enters the fair.
No of people attending the fair on Saturday is 8,633 amd No of people attending the fair on Sunday is 7,400.
We need to find the no of people that received a free admission over the two days.
Dividing 8,633 by 179 gives 48 as quotient and 41 as remainder. It means on Saturday 48 people entered for free.
Dividing 7,400 by 179 gives 41 as quotient and 61 as remainder. It means on Sunday 41 people entered for free.
Total no of people,
T = 48 + 41
T = 89
Hence, there are 89 people for free entries.

James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? Check all that apply.
7 x + 4 and 3 x + 5 + 4 x minus 1
When x = 2, both expressions have a value of 18.
The expressions are only equivalent for x = 4 and x = 6.
The expressions are only equivalent when evaluated with even values.
The expressions have equivalent values for any value of x.
The expressions should have been evaluated with one odd value and one even value.
When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
The expressions have equivalent values if x = 8.
Answer:
Two or more Algebraic expressions are said to be equivalent, if both the expression produces same numerical value , when variable in the expressions are replaced by any Real number.
The two expressions are
1. 7 x +4
2. 3 x +5 +4 x =1
Adding and subtracting Variables and constants
→7 x +5=1
→7 x +5-1
→7 x +4
→ When x=2,
7 x + 4 =7×2+4
=14 +4
=18
So, Both the expression has same value =18.
→So, by the definition of equivalent expression, when ,you substitute , x by any real number the two expression are equivalent.
Correct options among the given statement about the expressions are:
1.When x = 2, both expressions have a value of 18.
2.The expressions have equivalent values for any value of x.
3.The expressions have equivalent values if x = 8.
