Answer:
Step-by-step explanation:
Ooh I love these type of problems
Okay, here we go :
f = Fred and n = Nathan
f = 4n
f = n + 27
Above are the two equations (the words translated into algebra)
Now you can solve using substitution (any method works, but substitution is easiest for this problem)
4n = n + 27
3n = 27
n = 9
Since n = 9 substitute n into either equation
f = 4 * 9
f = 36
Fred is 36 and Nathan is 9

Classify the pair of angles.
O adjacent
O complementary
O supplementary
Onone of these
The pair of angles are acute angles.
The correct option is none of these.
What is an angle?The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.
Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.
We have,
The pair of angles of 30 and 30 are equal in measure.
But they are not adjacent, as they do not share a common vertex and a common side.
They are also not complementary, as complementary angles add up to 90 degrees, and 30 + 30 = 60.
Similarly, they are not supplementary, as supplementary angles add up to 180 degrees, and 30 + 30 = 60.
Therefore,
The pair of angles are none of the given options.

Lin is solving the inequality 15−x<14. She knows the solution to the equation 15−x=14 is x=1 How can Lin determine whether x>1 or x<1 Is the solution to the inequality?
Answer:
x > 1
Step-by-step explanation:
Given the inequality ; 15 - x < 14
Since the solution to the equation 15−x=14 is x=1 ;
Then we obtain the value of x for which the inequality expression is true :
If x > 1 ; take x = 2
15 - 2 < 14
13 < 14 (true)
If x < 1 ; take x = 0
15 - 0 < 14
15< 14 (not true)
Hence, solution is x > 1

0 Example: Loan payments of $400 due 95 days ago and $700 due today
are to be repaid by a payment of $600 thirty days from today and the
balance in 125 days. If money is worth 6% and the agreed focal date is
125 days from today, what is the size of the final payment?
Answer:
[tex]X=\$519.48[/tex]
Step-by-step explanation:
From the question we are told that
Loan 1 [tex]X_1=\$400[/tex]
Loan 1 due [tex]t_1=95days[/tex]
Loan 2 [tex]X_2=\$700[/tex]
Loan 2 due[tex]t_2=0days[/tex]
Payment [tex]Y=\$600[/tex]
Worth of money [tex]w=6\%[/tex]
Payment due [tex]t=30days[/tex]
Focal date [tex]t_f=125days[/tex]
Generally [tex]\$400[/tex] was due 95days ago
Therefore
[tex]125+90=220days[/tex](total days to consider)
Therefore
[tex]300+400 =700[/tex] is due today
125days left
Given
600 due in 30days
[tex]125-30=95days[/tex]
Generally the Final payment is mathematically given by
[tex]400(1+ 0.06*\frac{220}{365} ) + 700(1+0.06*\frac{125}{365} )=600(1+0.06*\frac{95}{365} )+X[/tex]
[tex]X=1128.9692 - 609.3698[/tex]
Therefore the
[tex]X=\$519.48[/tex]

I do not know how to find the x in this situation can anyone help?
Answer and Step-by-step explanation:
Essentially, the figure FEHG got scaled by a factor of 1.5, and turned into BADC
So 2.4 times 1.5 is 3.6
3.6 = x
Hope this helps! #teamtrees #WAP (Water And Plant)
Answer:
The x would be 3.6
Step-by-step explanation:
If you see the relation or ration between the ABCD triangle and the EFGH then we can see that the side 2 is multiplied by 1.5 to get to 3. so you do the same thing to 2.4 and multiple that by 1.5 and 3.6.

A rope weighs 800 grams per meter of length. What is the weight in kilograms of 12.2 meters of the rope?
Answer: the weight in kilograms is 9.76kg
Step-by-step explanation:
1 meter of length of rope = 800 g
12.2 meters of the rope= (12.2meters x 800g)/ 1 meter=9760grams
We know that 1000 g = 1kg
9760 grams = 9760/1000=9.76 kilograms
Help I’m confused big points to who can solve this
Answer:
n = 2
Step-by-step explanation:
Given nx + y = 4, if we rearrange in slope-intercept form: y = -nx + 4
This means that the y-intercept is 4. Point "A" is the y-intercept, which would make OA = 4, and OB = 1/2(4) = 2.
We can now solve for n. The slope here is "-n", also represented by rise/run or OA/-OB = 4/-2 = -2.
-n = -2,
n = 2
