Answer:
The sides of an equilateral triangle are same. So if one of the sides is (x-4.5), all the sides are (x-4.5).
Let the sides are a=(x-4.5), b=(x-4.5), c=(x-4.5)
1. Perimeter(as sum) = a+b+c
= (x-4.5)+(x-4.5)+(x-4.5)
= x+x+x-4.5-4.5-4.5
= 3x - 13.5
2. Perimeter (as product) = 3×a
= 3×(x-4.5)
= 3×x - 3×4.5
= 3x - 13.5
(you can write 3×b or 3×c also as a=b=c.)
Both perimeter as sum and perimeter as product are same as adding a number three times is the same as multiplying it by 3.

Answer:
Ok, so the answer is 3.5
Step-by-step explanation:
From what I could see it says walked for 14 around her block 4 times so your answer is 3.5 because if (Let's call her Patricia) Patricia walked around her block 4 times in 14 minutes, we have to find the unit rate, therefore we have to divide 14 by 4 as shown below
[tex]14/4=3.5[/tex]
Thus your only viable solution is 3.5

The chemistry teacher set out a 5 pound jar of salt at the beginning of the day. If each student needs 27.6 grams of salt for an experiment, how many students can perform the experiment before the jar is empty? (hint: 1lb=454grams)
Answer:
82 students
Step-by-step explanation:
In this, the first thing you should do is convert the five pounds to grams, which is 2270 grams. Now, all you need to divide 2270 by 27.6 to get the number of students because each student uses 27.6 grams and there 2270 grams being set each day. This gives you 82.2463768116 technically, but you should just round up, and that gives you 82 students. I hope this helped :D
Approximately 82 students can perform the experiment before the 5-pound jar of salt is empty.
In order to determine how many students can perform the experiment with the given jar of salt, we need to convert the jar's weight from pounds to grams, and then divide that by the amount of salt each student requires.
1. Given data: 1 pound = 454 grams (conversion factor).
2. The jar's weight is 5 pounds, so we multiply 5 by 454 to find the total grams of salt initially present in the jar:
5 pounds × 454 grams/pound = 2270 grams.
3. Each student needs 27.6 grams of salt for the experiment.
4. To find the number of students that can perform the experiment, we divide the total grams of salt by the grams per student:
Number of students = Total grams of salt / Grams per student.
Number of students = 2270 grams / 27.6 grams/student ≈ 82.42 students.
5. Since we can't have a fraction of a student, we round down to the nearest whole student (as we can't have a fraction of a student), yielding about 82 students.
6. However, we should also consider that after 82 students, there will be some salt left, but not enough for a complete experiment. Therefore, let's find out how much salt would be left after 82 students.
7. Salt used by 82 students = 82 students × 27.6 grams/student = 2263.2 grams.
8. Salt left in the jar = Total initial salt - Salt used by 82 students = 2270 grams - 2263.2 grams = 6.8 grams.
9. Since the remaining 6.8 grams is not sufficient for another complete experiment, we can conclude that approximately 82 students can perform the experiment before the jar is empty.
In conclusion, about 82 students can perform the experiment using the given 5-pound jar of salt.

Karina is baking bread. She buys a small bag of flour that contains 2[tex]\frac{2}{3}[/tex]cups of flour. The recipe calls for 2 [tex]\frac{5}{7}[/tex]cups of flour. Does she have enough flour to bake the bread? Explain how she can compare the fractions to know for sure.
Answer:
to compare she must calculate...
1) ((2*3)+2)/3 she get 2.666
2) ((2*7)+5)/7 she get 2.714
by approximation the two are the same and she had enough flour.
Using approximation, the two are the same and she has enough flour.
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given that Karina buys a small bag of flour that contains [tex]2\frac{2}{3}[/tex] cups of flour. The recipe calls for [tex]2\frac{5}{7}[/tex] cups of flour.
1) [tex]2\frac{2}{3}[/tex] cups of flour.
= ((2 x 3)+2)/3
= 2.666
Hence, she get 2.666
2) [tex]2\frac{5}{7}[/tex] cups of flour.
= ((2x 7)+5)/7
= 2.714
Hence, she get 2.714
Using approximation, the two are the same and she has enough flour.

Zachary purchased a computer for $1,600 on a payment plan. Two months after he purchased the computer, his balance was $1,370. Four months after he purchased the computer, his balance was $1,140. What is an equation that models the balance y after x months?
Answer:
Step-by-step explanation:
You are finding out each time how much is the items Zachary bought.
Then inputting a equation
$1,600 - ??? = $1,370
To find the unknown number, you must subtract the 2 original numbers.
$1,600 - $1,370 = $230
Computer costs: $230 leaving Zachary with $1,370 left.
Next, it says he purchased another computer...
$1,370 - ??? = $1,140
Again, we subtract the 2 original numbers to find the unknown.
$1,370 - $1,140 = $230 leaving Zachary with $1,140 left.
Now we input this data into an equation...
y = -230x + 1600.
Use mental math to find the difference.
