Write an express for the perimeter of the figure shown by combing like terms.
Answers
9514 1404 393
Answer:
28k
Step-by-step explanation:
The perimeter is the sum of the four equal-length sides:
P = 7k +7k +7k +7k
P = k(7 +7 +7 +7)
P = 28k . . . . perimeter of the rhombus
__
Of course, multiplication was invented to make repeated addition easier. Here, the perimeter is 4(7k) = 28k, no like terms to combine.

Alex is trying to run a certain number of miles by the end of the month Alex is 40% of the way to achieving her goal and she already has run 12 miles how many miles is she trying to run by the end of the month
Answers
Answer:
30 miles
Step-by-step explanation:
Given that:
Alex has some target to run a certain number of miles by the end of the month.
Goal already achieved = 40% of the total goal
Number of miles already run by Alex = 12 miles
To find:
Number of miles that Alex is trying to run by the end of month?
Solution:
We have to find nothing but the goal of Alex here.
Let the number of miles that Alex is trying to run by the end of the month = [tex]x[/tex] miles
As per question statement:
40% of total number of miles to be run = 12 miles
OR
[tex]\dfrac{40}{100}\times x = 12\\\Rightarrow 40x=12\times 100\\\Rightarrow x = \dfrac{1200}{40}\\\Rightarrow \bold{x = 30\ miles}[/tex]
Total number of miles that Alex is trying to run by the end of the month = 30 miles
Use the algebraic expressions for the length and width of Marlene's living room found in the
23.
diagram and the value of x found in Question 21C.
A. Find the actual length and width of her living room.
B
Find the actual area of Marlene's living room. Use actual dimensions.
Answers
Answer:
The area of Marlien's living room is 420 square ft
Step-by-step explanation:
Before calculating the real dimensions of Marlien's living room, we must find the value of x.
Given the total shape of the house is a rectangle, then both widths must be equal and both lengths must be equal.
The widths are already written width identical expressions x-2+x, but the lengths are given as different functions of x. Equating both expressions, we have:
[tex]2x-10+x-2+\frac{1}{2}x-4+x-2=2x+2+\frac{1}{2}x-4+x-2[/tex]
Simplifying:
-10 + x - 2 = 2
x = 10 + 2 + 2
x = 14
Since x=14 feet, the dimensions of Marlien's living room are
width=x=14 feet
length=2x+2=30 feet
Thus the area is:
A = 14*30 = 420 square ft
The area of Marlien's living room is 420 square ft
a coin jar holds dimes and quarters.A coin jar holds dimes and quarters. There are ten less quarters than dimes. There is a total of $3.80. How many dimes are in the jar
Answers
Answer:
There are 18 dimes in the jar
Step-by-step explanation:
Let
x = number of dimes in the jar
y = number of quarters in the jar
Total = $3.80
There are ten less quarters than dimes
y = x - 10
0.1x + 0.25y = 3.80
0.1x + 0.25(x - 10) = 3.80
0.1x + 0.25x - 2.5 = 3.80
0.35x = 3.80 + 2.5
0.35x = 6.30
x = 6.30/0.35
x = 18

Answers
Answer:
So you have a summation of 4 terms
An Easy way to do this is to simplify the process:
You need X1+X2+X3+X4 to equal 214
Let the first number be 80
80+X2+X3+X4
Let X2 and X3 be 60 each
80+ 60+ 60+X4
Lastly we are at a sum of 200
So let X4 be 14
Therfore we have a sum of 4 X terms equal 214

Francisco is saving money in an account. At the beginning of the year, he has $56 in savings
and puts in another s4 per week. Which of the following equations models the amount of
savings, s, as a function of the number of weeks, w, Francisco has been saving?
Answers
Explanation do 52 times 4 equals 208 plus 56 and you get 264
The correct equation for this given condition is;
⇒ s = $56 + $4w
Where, 's' is amount of savings and 'w' is number of weeks.
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
Francisco is saving money in an account.
The savings amount = $56
And, Put in another $4 per week.
Now,
Let number of weeks = w
And. Total amount in saving amount = s
So, We can formulate;
⇒ s = $56 + $4w
Thus, The correct equation for this given condition is;
⇒ s = $56 + $4w
Where, 's' is amount of savings and 'w' is number of weeks.

Company sells drinks in packs and cases a bottle is 1/6 of pack and the pack is 1/12 of a case a case of the drink called 25.92 what is the price per bottle in a case
Answers
Answer:
0.36
Step-by-step explanation:
Company sells drinks in packs and cases a bottle is 1/6 of pack and the pack is 1/12 of a case a case of the drink called 25.92 what is the price per bottle in a case
From the above question:
1 pack = 1/12 of a case.
1/12 of a case = 1 pack
1 case = x packs
Cross Multiply
1/12 × x = 1 × 1
x = 1 / 1/12
x = 1 × 12/1
x = 12 packs
This means, 1 case of drinks contains 12 packs of drinks
We are also told that: a case of the drink cost 25.92
This means the cost of 12 packs of drinks = 25.92
We are also told that:
a bottle is 1/6 of pack
1/6 pack = 1 bottle
1 pack = x bottles
Cross Multiply
1/6 × x = 1 × 1
x = 1 / 1/6
x = 1 × 6/1
x =6 bottles
This means, 1 pack of drinks contains 6 bottles of drinks
Hence:
12 packs of drinks = 25.92
1 pack of drinks = x
Cross Multiply
12x = 25.92
x = 25.92/12
x = 2.16
1 pack of drinks cost 2.16= 6 bottles of drinks cost 2.16
Therefore:
6 bottles of drinks = 2.16
1 bottle of drink = x
Cross Multiply
6x = 1 × 2.16
x = 2.16/6
x = 0.36
Therefore, the price per bottle in a case is 0.36
