Answer:
n = -23
Step-by-step explanation:
3n + 7 - 11n - 31 = 160
Step 1: Combine like terms
-8n - 24 = 160
Step 2: Simplify
-8n = 184
n = -23
Answer:
= −23
Step-by-step explanation:
Subtract the numbers
3 + 7 - 11-31 = 160
3-24 - 11 = 160
Combine like terms
3 - 24-11 = 160
-8 - 24 = 160
Add 24 to both sides of the equation
-8 - 24 = 160
-8 - 24 + 24 = 160 + 24
Simplify
Add the numbers
Add the numbers
--> -8 = 184
Divide both sides of the equation by the same term
-8 = 184
-8/-8 = 184/-8
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
--> = -23
Solve the equation 3(5x-2)-3x=30
The answer is X=3, ur welcome :)
Answer: 3
Step-by-step explanation:
3(5x-2) - 3x = 30
15x - 6 - 3x =30
15x -3x = 30 + 6
12x = 36
X= 36/ 12
X = 3

Step-by-step explanation:
State University has no honors English course but instead places all freshman scoring at least 60 on a proficiency exam (mean=50, standard deviation=10) into an advanced composition course. If the scores are normally distributed and there are 2,500 entering freshman, how many will be put into the advanced course?
Answer:
that put into the advanced course is 396.75
Step-by-step explanation:
The computation of that put into the advanced course is shown below:
P(X>60)
= P((X - mean) ÷ s > (60 - 50) ÷ 10)
= P (Z > 1)
= 0.1587
It could be checked by the standard normal table
Now that put into the advance course is
= 2,500 × 0.1587
= 396.75
Hence, that put into the advanced course is 396.75

A homeowner uses GGG hours of natural gas heat and PPP hours of heat from a pellet stove to heat her house one month, with a total of 575757 therms of output. How many therms per hour does the pellet stove output
Answer:
0.0792therms/hour
Step-by-step explanation:
Given
Total output per month = 57 therm of output
Required
Total output of the pellet stove in one hour
Since 1month = 24×30 = 720hours
Hence:
57therms = 720hours
x therm = 1hour
Cross multiply
720×x = 57
x = 57/720
x = 0.0792 therms/hr
Hence the pellet stove use 0.0792therms/hour

bcz root of 121 is 11. then 2/3 +11 will give you a rational number.
Answer:
2/7 + square root of 121 (the third one)
Step-by-step explanation:
a rational number is a number where if you write it as a fraction, both the numerator and denominator are integers (numbers like 1 and 2 but not like 3.4 or 5.6)
the equation simplified a bit looks like this:
2/7 + 11/1
anddd so all the numbers are integers which means that expression is correct :3

Match the following words to the correct definition:
_____ translation ______ rotation ______reflection _____dilation
A. Flip B. Enlarge/reduce C. Turn D. Slide
Answer:
A. Flip ---> reflection
B. Enlarge/reduce ---> dilation
C. Turn ----> rotation
D. Slide ----> translation
Step-by-step explanation:
D and translation
A and reflection
C and rotation
B and dilation
it just makes sense.
dilation means like if you stung by a bee and it starts to swell but it can also be used as a way to say something shrunk.
reflection means yourself flipped
rotation means like your turning around or turning something around
i don't know if translation has anything to do with slide but it was the last option and all the others make sense.

Kelsea and Landon are playing in a park standing 100 feet away from each other. They both see a bird flying above them. The angles of elevation from each person to the bird are shown. How high is the bird from the ground? Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
use an ASA triangle with law of sine
since we know that 180 = 20 +45 + C .. solve for C = 115°
now use law of sines c/ sin(C) = b/sin(B) .. and solve for b
Sin(20)*100/sin(115) = b
b = 37.73774 ft
that's the hypotenuse of the 45 triangle
SOH CAH TOA to remember how trig functions fit
use b*Cos(45) = adj
26.6846 = adj
The bird is 26.7 ft. from the ground
