Which equation represents this statement?
23 times a number is 65
23=n+65
23n=65
23+n=65
23=65n
Answer:
The correct equation is 23n=65
Step-by-step explanation:
23n=65 means a number 'n' multiplied with 23 gives you the product 65.

A hotel has number of meeting rooms m available for events each meeting room. Has 325 chairs write equation to represent c the total number of chairs in all of the meeting rooms at the hotel
Answer:
2,275
Step-by-step explanation:
c=325m
Because for every meeting room there is 325 chairs and c=the total of chairs
and c=325(7) so c=2,275
so the answer is 2,275
Find an equation for the horizontal line through the point (2,−8).
Answer:
X=2
Step-by-step explanation:
X is the horizontal line and in this coordinate pair, 2 is our X. Therefore X=2
Answer:
y = -8
Step-by-step explanation:
You can have a horizontal line parallel to the x-axis which is also known as y=c. Since you had the point (2,-8) you can simply write y = -8 as an equation.

Answer:
Step-by-step explanation:
iii) ∠AOE + ∠DOE + ∠DOB = 180 {Straight line angles}
67 + ∠DOE + 100 = 180
∠DOE = 180 - 167
∠DOE = 13°
ii) ∠BOC = ∠AOD {Vertically opposite angles}
∠BOC = ∠AOE + ∠DOE
= 67 + 13
∠BOC = 80°
i) ∠AOC = ∠BOD
∠AOC = 100°

Answer:
x = 3Sides are 6, 8 and 10Step-by-step explanation:
Use Pythagorean to find the value of x:
c² = a² + b²Consider:
a = x + 3, b = 3x - 1, c = 4x - 2Substitute and solve for x:
(4x - 2)² = (x + 3)² + (3x - 1)²16x² - 16x + 4 = x² + 6x + 9 + 9x² - 6x + 116x² - 10x² - 16x + 4 - 10 = 06x² - 16x - 6 = 03x² - 8x - 3 = 03x² - 9x + x - 3 = 03x(x - 3) + (x - 3) = 0(x - 3)(3x + 1) = 0x - 3 = 0, 3x + 1 = 0x = 3, x = - 1/3Positive root is accepted only.
Sides of the triangle:
a = x + 3 = 3 + 3 = 6b = 3x - 1 = 3*3 - 1 = 8c = 4x - 2 = 4*3 - 2 = 10Here are fractions A) 2/5 B) 2/3 C) 1/4 D) 1/4
Answer:
0.5 can also be written as 1/2 so we can eleminate the ones that are greater than 1/2 and put them ahead of 0.5 on the number line.
Since 2/3 is approximately 0.666666666666 we can put that above 0.5
2/5=0.4
1/4=0.25
1/10=0.1
Knowing this... The answer is D,C,A,B
Hope this helps

It takes Rick, traveling 36mph, 40 minutes longer to go a certain distance than it takes Evelyn traveling at 84mph. Find the distance traveled
d = r · t and we know that the distance is the same.
Let x = time it takes Evelyn (in hours, since the rate is mph).
Evelyn's distance is 84x.
Rick's distance is 36·(x+2/3) since 40 minutes longer is 2/3 of an hour longer
84x = 36(x+2/3)
84x = 36x + 24
48x = 24
x = 1/2
So it takes Evelyn 1/2 an hour, meaning the distance is 84(1/2) = 42 miles
To confirm this, it would take Rick 42/36 hours or 1 and 1/6 hours. That's 70 minutes, which is 40 minutes longer than Evelyn's 1/2 hour trip.
The distance is 42 miles.

My name is Pauley the Parrot and I have a dilemma. Blackbeard found a
chest full of gold and he wanted to divide it evenly among the crew. The
chest weighed 12 pounds because it was filled to the top with gold. There
are 24 crew members (including myself and Blackbeard) on the boat. I told
him that if he gave each crew member 2 lbs. of gold there would be enough
to go around. Blackbeard said that he could give each crew member { lb of
gold and there would be enough to go around.
Can you help us figure out who is correct? Make sure to explain who was
correct, and why the other person was incorrect. Maybe, I can split my
earnings with you!

Between a and b is 10 between a and c 6 these are for the small triangle
between r and q is m and between q and s is 9
help me find m
I WILL MARK BRAINEST
Answer:
m=15
Step-by-step explanation:
since side QS is 9 and side AC is 6 which is 1.5 times bigger so there is a dilation of 1.5 meaning all sides are 1.5 times bigger on the right triangle than the left triangle. Side AB is 10 so 1.5 times 10 is 15 so m=15
A new company president is said to have caused the company "to do a 180." Before the new president, the company was losing 10,000 per month .What is the company most likely doing under the new president?
Answer:
Earning 10,000 per month.
Step-by-step explanation:
Since a "180" usually refers to an opposite, the opposite of "losing 10,000 per month" would happen.
So, the company would be earning money instead of losing money.

What is ratio?Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Genesis mows in 1/6 hour =1/3 lawns
To find, mow per hour,
∴ in 1/6 hours =1/3 lawn,
⇒1 hour = 6×1/3 lawn
⇒1 hour = 2 lawns.
So, In 1 hour, Genesis can mow 2 lawns.
