What is the value of n in the equation below? 9 n − 24 = 4 n + 6 A. –3 B. –6 C. 5 D. 6
First you want to get n on the side by itself.
So 9n-24=4n+6 you want to add 24 to both sides so you get 9n=4n+30 than you want to subtract 4n from both sides to get 5n=30 than divide 5 from both sides to get n by itself and you will get n=6
A 12-foot ladder is placed 4 feet away from a house as shown.
A 12 foot ladder is leaning against a house to form angle x. The distance between the house and the bottom of the ladder is 4 feet. The angle between the house and the ground is 90 degrees.
What is the value of x, rounded to the nearest degree?
x ≈
°
According to the manufacturer, if the angle the ladder forms with the ground, x, is between 70° and 75°, then it meets safety standards.
Is this ladder being used safely?
Answer:
Answer: x = 71 degrees. Yes, the ladder meets safety standards
Discussion:
The problem describes a right triangle with hypotenuse 12, the side against the ground is 4, and the angle between those two sides is "x". For this triangle,
cosx = (side adjacent to angle) / hypotenuse
= 4 / 12
= 1/3
To find "x" take the inverse cosine of each side to find that :
x is approximately 70.52 degrees. That's 71 degrees rounded to the nearest degree.

What is the slope of the equation y = 5x - 7?
o
-7
o
7.
Answer:
slope = 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 5x - 7 ← is in slope- intercept form
with slope m = 5
Answer:
The slope is 5.
Step-by-step explanation:
y=mx+b is the equation used to plot a line, where m is the slope and b is the y intercept.

Answer:
f(x)=0.5x+3.5, x<1
f(x)=-2x+6, x>1
Step-by-step explanation:
Find the Point of Interest, which is at x=1 because the direction changes. Find the slope (rise/run) of the line on the left which is 1/2 or 0.5. Find the y-intercept by plugging in the given point: (-3, 2). 0.5(-3)+c=2 so the y-intercept is 3.5. Do the same for the line on the right.
4(x-5)=10(x-10)
solve for x
Answer:
40/3
Step-by-step explanation:
4x -20 = 10x -100 (Distributive Property)
4x -10x = -100 +20 (I swith the numbers so all of them are similar)
-6x= -80 (Divide -6 on both sides)
And you will get 40/3 or 13.3333..
Answer:
x = 40/3
Step-by-step explanation:
4(x-5)=10(x-10)
=> 4x - 20 = 10x - 100
=> 4x - 10x = - 100 + 20
=> -6x = -80
=> x = 80/6
=> x = 40/3

a. -4 and 4b + 4
b. 3x and 1 -3x
Answer:
Does this problem have a picture, I just need to make sure I am seeing everything correctly thanks!
Step-by-step explanation:
a. -4 and 4b + 4 = 4b
-4 and 4b + 4 = -4 + (4b + 4) = 4b + (4 - 4) = 4b + 0 = 4b
b. 3x and 1 - 3x = 1
3x and 1 - 3x = 3x + (1 - 3x) = 1 + (3x - 3x) = 1 + 0 = 1
A butcher has 3 1 3 pounds of ground beef that will be priced at $1.35 per pound. He divides the meat into 8 equal packages. To the nearest cent, the price of each package is $ .
Answer:
$0.56
Step-by-step explanation:
Cost of 3 1/3 pounds of beef at $1.35 per pound
= 3 1/3 × 1.35
= 10/3 × 1.35
= $4.5
He divides the meat into 8 equal packages. To the nearest cent, the price of each package is $
= $4.5 / 8
= $0.5625
Approximately $0.56 to the nearest cent

An empty box weighs 200 g the boxes filled with party goody bags and now it weighs 6.2 kg each goodie bag weighs 100 and grams work out how many goody bags are inside the box
Answer:
60 goody bags
Step-by-step explanation:
1 kg = 1000 g
6.2 kg = 6,200 g
Empty box = 200 g
Box + goody bags = 6,200 g
Weight of Goody bags = Box + goody bags - empty box
= 6,200g - 200g
= 6,000 grams
Each goody bag = 100 g
how many goody bags are inside the box
Number of goody bag in the box = total weight of goody bag / weight of each goody bag
= 6,000 grams / 100 grams
= 60 goody bags
There are 60 goody bags in the box

Write in slope intercept: slope=2/3 y-intercept =-1
Answer:
y=2/3-1.
Step-by-step explanation:
Slope intercept is the easiest out of the forms because you just plug in what is given. Here you are given 2/3 for the slope and the y-int Is -1.
The formula for slope intercept is y=mx+b
m= slope
b= y-int
And you just plug it in.
so the answer would be: y=2/3-1. Hope this helps!
