Answer:
x=5
Step-by-step explanation:
-5x+6(5x-18)=17
-5x+30x-108=17
25x-108=17
25x=17+108
25x=125
x=5
Solve for s
3(s + 2) = 3
Answer:
s=-1
Step-by-step explanation:
Distribute the 3 to the (s+2) [tex]3(s+2)= 3s+6[/tex]
Subtract 6 from three [tex]3s+6=3 -> 3s=-3[/tex]
Divide -3 by 3 [tex]3s=-3 -> s=\frac{-3}{3}[/tex]
Simplify to -1
answer the following question
Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) x = 5
You can get this with a calculator if you need by using the log function.
[tex]log_{2} 32 = x[/tex]
x = 5
b) x = 4
According to the product rule of exponents: [tex]a^{x} * a^{y} = a^{x + y}[/tex]
So, x + 11 = 15 --> x = 4

On an airplane, there are two seats on the left side in each row and three seats on the right
side. There are 160 seats altogether.
Answer:
I don't think you put the whole question, but if you're asking how many rows there are, it's 32
Step-by-step explanation:
Answer:
32 rows??
Step-by-step explanation:
If you are looking for rows it would be 32. A total of 5 seats in a row, 160 divided by 5, is 32.
∠ = 150 and∠ = 80. Find ∠. The diagram is not to scale
Answer:
I don't see the diagram but if you're adding to 360 degrees than the answer is 90

after changing the amount of time he works Seth has begun earning a salary of $214,206 that is 5% less than before how much does Seth’s salary used to be
Answer:
seth's new old salary was $224,916
Step-by-step explanation:
You take 214,206 and multiply it by .05 which is 5%
you take the number u got from multiplying that and add it onto the existing "salary" which is $214,206 and 5% of 214,206 is 10,710. you then add that onto 214206 and u get ur answer. Hope this helped.

Identify the function in this graph
Answer:
what's the graph?
Step-by-step explanation:
Please! I'M IN A HURRY. 40 POINTS!
The graph of g is a vertical shrink of the graph if f. What can you say about the x-intercepts if the graphs of f and g. Is this always true? Explain.
Answer:ok ok your answer is...sample response!
g(x) = f(5x)
Step-by-step explanation:
We assume that "shrink by a factor of 1/5" means that horizontal distances on the graph of g(x) are 1/5 of those on the graph of f(x).
Dividing x by a dilation factor will cause horizontal dilation of a graph. Here, that factor is 1/5, so the desired function is ...
g(x) = f(x/(1/5))
g(x) = f(5x)

If △NMK ≅ △TRP, then answer the following questions:
a. Complete the congruence statement: △MNK ≅ △_______
b. What side is congruent to ≅ ______
c. Solve for x. _____
Answer:
A-△MNK ≅ △RTP
B- TR≅NM
C- X=7
Step-by-step explanation:
I did the assignment loves.
The given statements to be completed are completed as follows;
A) △MNK ≅ △RTP
B) TR ≅ NM
C) x = 7
We are given that;
△NMK ≅ △TRP
This means that Triangle NMK is congruent to Triangle TRP.
A) The naming of △NMK is now △MNK. Thus, we have to now re-name Triangle TRP to match the naming of △MNK. Thus;
△MNK ≅ △RTP
B) From the 2 given triangles, we can see that TR and NM are the same length and also perpendicular lines.
Thus they are congruent to each other and as such;
TR ≅ NM
C) Since TR and NM are congruent to each other. Then;
TR = NM
Thus;
3x - 1 = 20
3x = 20 + 1
3x = 21
x = 21/3
x = 7

The sum of the digits of a two digit number is 9 When the digits are reversed the number increases by 9. Find the number.
Answer:45
Step-by-step explanation:
Let the unit place be ‘x'
Tenth place be y
The number is 10y+x
x+y = 9 (according to the condition) (1)
Digits are interchanged Unit place' y ‘& tenth place ‘ x'
New no is 10x +y
This is 9 more than the original number
10x+ y = 10y+x +9
10x-x+y-10y = 9
9x-9y= 9
x-y = 1 (dividing by 9) (2)
Adding the two equations
2x = 10
x= 5
Substituting the value of x in first equation
y = 4
The number is 45, the original number is 54 this is 9 more of the new number.
