During a winter cold spell the temperature change was -1.2 f per hour for a period of 4.5 hours which expressions can be used to find the overall change in the temperature during that time period.
A.) 4.5 divided (-1.2) degrees Fahrenheit
B.) 4.5x (-1.2) degrees Fahrenheit
C.) 4.5 - (-1.2) degrees Fahrenheit
D.) (-1.2)+(-1.2)+(1.2)+(1.2) degrees Fahrenheit
E.) 4(-1.2)+(0.5)(-1.2) degrees Fahrenheit
Answer:
B.) 4.5x (-1.2) degrees Fahrenheit
-3x=2x+19 solve for x
Solve the equation by showing the work
-4x + 2 = -18
Answer:
x = 5
Step-by-step explanation:
-4x + 2 = -18
subtract 2 from both sides
-4x + 2 - 2 = -18 - 2
simplify
-4x = -20
divide both sides by -4
-4x/-4 = -20/-4
simplify
x = 5
hope this helps :) have a nice day !!

Which expression is equivalent to 4/5x + 1 1/5?
A. 1/5 (4x + 1)
B. 2/5 (2x + 3)
C. 4/5 (x + 2)
D. 5/4 (x + 1)
I'd love it if you gave me an explanation for this.
Answer:
The answer would be B!
Step-by-step explanation:
To find which expression is equivalent, do the distributive property.
A. 1/5 * 4x = 4/5x
1/5 * 1/1 = 1/5
4/5x + 1/5 <--- This is wrong!
B. 2/5 * 2x = 4/5x
2/5 * 3/1 = 6/5 = 1 1/5
4/5x + 1 1/5 <--- This is correct!
C. 4/5 * x = 4/5x
4/5 * 2/1 = 8/5
4/5x + 8/5 <--- This is wrong!
D. 5/4*x = 5/4x
5/4 * 1/1 = 5/4
5/4x + 5/4 <--- This is wrong!
Therefore, the answer is B! Hope this helps!

2. Suppose you are a new employee. You notice that each payment option describes a sequence and decide to use rules to help determine which option to take.
(a) Determine the iterative rule for each sequence. Show your work.
(b) Your friend trusts your tables in Problem 1, but wonders if you wrote the iterative rules correctly. Show two calculations to convince your friend that both your rules work.
3. Consider the iterative rules you wrote in Problem 2.
(a) Explain why the rules are functions.
(b) Your friend says that because the rules are functions, they can be graphed and must have y-intercepts. How would you respond to your friend’s comment?
(c) Your friend uses your rules to determine the outputs when the inputs are 18.5. Explain why her outputs are meaningless in this situation. What would you tell her about the inputs she can use?
>THESE ARE NOT MULTIPLE CHOICE QUESTIONS!
Will give brainliest to anyone who answers all letters of both questions.
I only solved Option A in this answer, I think you needed to do both. You can do Option B in the same way!
2.
(a) You're supposed to find the pattern here. Use the slope-intercept form of the equation of a line. y=mx+b. In this situation, x is the week, and y is the amount paid. If you wanted, you could use whichever variables you wanted, of course. Basically, you need to find the slope, represented by m, which is the amount the amount paid increases by each week, and the y-intercept, b, which is the "amount paid" at week 0. (The y-intercept doesn't really make sense in this situation, but we'll get to that later.) You can use the formula m=(y2-y1)/(x2-x1). (x1,y1) and (x2,y2) are the input/output pairs. The x-coordinate is the week, and the y coordinate is the amount paid. Because the weeks are incrementing by 1, x2-x1=1. Because of this, you can just subtract the values and find out the slope is 50/week. After that, to complete the rule, you need to find the y-intercept. If the amount paid is 200 on week 1, and the amount paid increases by 50 each week, then you should be able to work backwards. 200-50=150
Another way to think about it is by plugging your points into the incomplete rule. Let b represent the y-intercept. Plug in the values for week 1 and solve for b.
Your work would probably look something like:
m=(y2-y1)/(x2-x1)
(x1,y1)=(1,200)
(x2,y2)=(2,250)
m=(250-200)/(2-1)
=50/1
=50
y=50x+b
200=50(1)+b
200=50+b
b=200-50
=150
y=50x+150
(b) If I understand the question correctly, you have to show two instances that prove that your rule work. Just pick any two weeks, like weeks 3 and 4 and show how the rule is correct.
y=50x+150
x=3
y=50(3)+150
=150+150
=300
(This is the same value that's in the chart, which proves that the rule works. Do the same thing with another week.)
3.
(a) The rules are functions because each input has only one output. You can test this out, it's true.
(b) So we did have to find the "y-intercept" earlier. But you have to look at the domain. There won't be any amount paid on Week 0, payment starts at Week 1. So you would have to respond that yes, they can be graphed, but there's no y-intercept; the graph starts at week 1. Aditionally, there are only data points at the integer values of x. Look at part c.
(c) The outputs are meaningless because you're counting the time by weeks. There won't be any amount paid in the middle of the week, so she can only use integer inputs.
I hope this helps!! This is my first time answering a question on here.

Here is Priya's calculation of 906 divided by 3
Priya wrote 320 for the value of 906 +3. Check her answer by multiplying it by 3. What product do you get and what does it tell you about Priya's answer?
correct answer is 302**
Answer:
Her mistake is that she wrote a two in the tenths place and zero in the ones place.
Step-by-step explanation:
3 can't go into zero so she had to write a zero in the tenths place. And 3 can go into 6 two times so she must write a 2 in the ones place.
Hope this Helps :)

Answer:
I think 157 pavers
Step-by-step explanation:
I may be able to help with number 10, if the trees are to be decorated with a ring of decorative pavers then we have to find the circumference, if the radius is 5 then using the circumference formula, 2×3.14(pi)×the radius, you'll get 31.4 and since there is 5 trees to be decorated then multiply 31.4 times 5 which will give you 157 feet of pavers to surround all five trees. I apologize if it is incorrect.
