3 (n - 4) = 36
please show work if you can
Answer:
n=16
Step-by-step explanation:
3 (n-4) = 36
3n -12=36
add twelve to both sides. because -12 + 12 is 0. and once you are at zero, you can cancel it out.
3n=48
divide by 3 on both sides
n=16
please help due at 11 !! thank you so much
Answer:
13cm
Step-by-step explanation:
The pythagorean theorem states that, for right triangles, [tex]a^{2} +b^{2} =c^{2}[/tex]. Using this equation, we can solve for the hypotenuse.
a = 12cm
b = 5cm
c = hypotenuse
[tex]12^{2} +5^{2} =c^{2}[/tex]
[tex]144+25=c^{2}[/tex]
[tex]\sqrt{169} =c[/tex]
13 = c
Answer:
13
Step-by-step explanation:
a^2+b^2=c^2
12^2+5^2=c^2
144+25=c^2
169
square root of 169=13
13=c

long. What is the measure of the longest side of the triangle?
Answer:
42.42641
Step-by-step explanation:
A major storm has winds speeds that are at least 110 miles per hour.Write and solve an inequality that describes how much greater these wind speeds are than the slowest hurricane
Answer:
x ≥ 36 miles per hour
Step-by-step explanation:
The speed of a major storm is at least 110 miles per hour while the speed of the slowest hurricane is at least 74 miles per hour.
Let x represent how much greater these wind speeds are than the slowest hurricane. Therefore:
x ≥ 110 miles per hour - 74 miles per hour
x ≥ 36 miles per hour
This means that the winds speed must be 36 miles per hour greater than the slowest hurricane.

8n+16.2=1.6
Plzzz
Help ,
Answer:
8n+16.2=1.6
n=-1.825
Step-by-step explanation: Subtract 16.2 from both sides 8n+16.2-16.2=1.6-16.2
Simplify 8n=-14.6/8
n=-1.825
Answer:
-1.825
Step-by-step explanation:
8n + 16.2 = 1.6
(step1)
8n + 16.2 = 1.6
- 16.2 -16.2
8n = -14.6
(step2)
8n = -14.6
---- ------
8 8
(step3)
-1.825
1. subtract 16.2 from both sides, you have to get rid of the number that is being add/subtracted to get the n and result alone
2. divide by the number next to the variable since you have to get the variable alone in order to find out what it is. you divide because you have to do the opposite of what the variable IS doing.
3. get the result lol

HELP ME PLEASE I DONT UNDERSTAND
the ratio 20 minuets to 1 hour can be written in the form 1:n
find the value of n
the answer is 1:3 since there are 60 minutes in on hour you divide 60 by 20 and get 3 so you have 3 sets of twenty minutes to one hour. so n is 3

What is the domain of the function graphed?
Answer:
C lets look at were this line starts which is in between 7 and 8 right in the middle making it 7.5 it is negative because the point is on the negative side of our graph. Where the line ends in on positive 2 on the x-axis. -Your friend, Bill Cipher

Answer: Choice (2) 3x-1 = 2x+3===============================================
Explanation:
We will plug x = 7 into each equation or inequality given to us. Then we determine if we get a true statement or not.
----------------
Let's start with choice (1)
x + 3 > 6
7 + 3 > 6 .... x is replaced with 7
10 > 6
Since 10 is larger than 6, this makes the last inequality true. Therefore, the first inequality is true when x = 7. So we can rule out choice (1) since we are looking for a false statement.
----------------
Move onto choice (2)
3x-1 = 2x+3
3*7-1 = 2*7+3 ... replace every x with 7
21-1 = 14+3
20 = 17
This is false since we don't get the same number on each side. Therefore, choice (2) is the final answer.
----------------
Since we found the answer, we can stop here. But let's keep going to check the others.
choice (3)
2(x+1) = x+9
2*(7+1) = 7+9 ... plug in x = 7
2*(8) = 16
16 = 16
We get the same thing on both sides, so the equation is true. We can rule out choice (3).
-----------------
Now onto choice (4)
[tex]-2x + 10 \le 0\\\\-2*7 + 10 \le 0\\\\-14 + 10 \le 0\\\\-4 \le 0\\\\[/tex]
This is true since -4 is to the left of 0 on the number line, which makes -4 smaller than 0. We can rule out choice (4).

Hope it will help :)
Answer:
5 milesfollow meThe average distance from the Sun to Mars is 22,793, 910,000,000 centimeters.
The conversion factors between centimeters and four other units of measure are shown below.
9.46. 10^17 cm = 1 light-year
1.50.10^13 cm = 1 astronomical
1 . 10^5 cm = 1 kilometer
1. 10^2 = 1 meter
For the distance to be expressed as x units of measure, where 1 < x < 10, which unit of measure must be used?
A Light-years
