First of all, we will subtract [tex]5[/tex] from each side.
[tex]\frac{2x-3}{4}=5[/tex]Then we multiply both sides by [tex]4[/tex].
[tex]2x-3=20[/tex]Then add [tex]3[/tex] to each side.
[tex]2x=23[/tex]Finally, we divide each side by [tex]2[/tex].
[tex]x=\frac{23}{2}=11.5[/tex][tex]\boldsymbol{\sf{\cfrac{2x-3}{4}+5=10 }}[/tex]
Multiply the two sides of the equation by 4.
2x - 3+20 = 40
Add −3 and 20 to get 17.
2x+17 = 40
It remains 17 on both sides.
2x = 40−17
Subtract 17 of 40 to get 23.
2x = 23
Divide both sides by 2.

A red ballon is 40 feet above the ground and rising at 2 ft/s. At the same time, a blue balloon is at 60 feet above the ground and descending at 3 ft/s. What will the height of the balloons be when they are the same height above the ground
Answers
Answer: 48 ft
Step-by-step explanation:
The height gap between the balloons is 60 -40 = 20 feet. That gap is being closed at the rate of 2 + 3 = 5 ft/s, so will be gone in ...
(20 ft)/(5 ft/s) = 4 s
At that time, the red balloon will have risen (2 ft/s)(4 s) = 8 ft to a height of ...
40 ft +8 ft = 48 ft
The blue balloon will have descended (3 ft/s)(4 s) = 12 ft to a height of ...
60 ft -12 ft = 48 ft
The balloons at at 48 ft when they are both the same height.
_____
Time and speed and distance are related by the formula you see on every speed limit sign:
speed = distance/time . . . . . . . (on the sign, it's "miles per hour")
or
time = distance/speed
or
distance = speed × time
_____
If you want equations, you can write them as ...
h = 40 +2t
h = 60 -3t
where h is the altitude the balloons have when they are at the same height, and t is the number of seconds it takes to get there.
We're only interested in h, so we can cancel t by multiplying the first equation by 3 and adding that to the second equation multiplied by 2:
3(h) + 2(h) = 3(40 +2t) +2(60 -3t)
5h = 120 +6t +120 -6t
h = 240/5 = 48 . . . . the height in feet at which the balloons are the same height

Answers
The proper test statistic has a value of 13.21.
As a result, repeated measurements of cholesterol levels from the same blood sample are taken to assess a lab technician's consistency.
The desired accuracy is a measurement variance of 2.78 or less. In the event that the lab technician conducts 16 measurements, and the sample's measurement variance is 2.45.
1) n=16 samples were used.
The desired accuracy is a measurement variance of 2.78 or less.
The sample's measurements' variance is 2.45 or less.
We list both the null and alternative hypotheses in response to the query.

2)Calculate the appropriate test statistic's value.
Using Chi-square,

a 13-ft ladder rests against a vertical wall. if the bottom of the ladder slides away at 1 ft/s, at what rate is the top of the ladder sliding down the wall when the bottom of the ladder is 5 ft from the wall? g
Answers
The given situation can be solved using the differential equation and the top of the ladder slides downward at 0.417 ft/s.
Let:
x be the distance from the bottom of the ladder to the base of the wall
y be the distance from the top of the ladder to the bottom of the wall
When the ladder is still, apply the Pythagorean Theorem,
x² + y² = 13²
5² + y² = 13²
y² = 169 - 25 = 144
y = 12 ft
When the ladder slides, apply the differential equation:
x² + y² = 13²
2x . dx/dt + 2y . dy/dt = 0
Substitute x = 5, dx/dt = 1, y = 12
2 . 5 . 1 + 2 . 12 . dy/dt = 0
24 dy/dt = -10
dy/dt = -5/12 = - 0.417 ft/s
The minus sign indicates that the ladder is sliding downward.

The equation that represents the total amount of money Papi's made selling pizzas on Saturday is (39 x $9.99) + (62 x $11.99) + (83 x $13.99)
Equation:
An equation is the mathematical statement which is made up of two expressions connected by an equal sign.
For example, 3x – 2 = 16 is an equation.
Given,
There are three types of pizza varieties are small, medium and large. And the price of them are $9.99, $11.99 and $13.99 respectively.
On Saturday, Papi's sold 39 small pizzas, 62 medium pizzas, and 83 large pizzas.
So, we have to write the equation for the total amount of money Papi's made selling pizzas on Saturday.
To calculate the price of the pizza we have to multiply it by the number of items sold by the cost.
So, the equation to calculate the cost of pizza,
=> number of items sold x cost.
Here we have to write the equation for three types and we have to find the total cost for it,
So, the equation is looks like,
=> (39 x $9.99) + (62 x $11.99) + (83 x $13.99)

If two angles be 10x + 5 and 15x - 30 then the value of x = 7.
How to find the value of x?Let the two angles be 10x + 5 and 15x - 30.
simplifying the above two equations, we get
10x + 5 = 15x - 30
Subtract 5 from both sides
10x + 5 - 5 = 15x - 30 - 5
Simplifying the above equations,
10x = 15x - 35
Subtract 15x from both sides of the equation
10x - 15x = 15x - 35 - 15x
Simplifying the above equation, we get
-5x = -35
Divide both sides by -5

Given diagram is a solid prism of a triangular base. if the base of the prism is 480 cm cube. find its height .
Answers
Answer:
20 cm
Step-by-step explanation:
Given a prism with a right triangle base and a volume of 480 cm³, you want the height of the prism. The base has one side 8 cm, and hypotenuse 10 cm.
Base edgeThe missing edge of the right triangle base can be found using the Pythagorean theorem. It tells us the square of the hypotenuse is the sum of the squares of the other two sides:
b² = c² +a²
10² = 8² +a² . . . . . . . use given lengths
a² = 100 -64 = 36 . . . . subtract 8², simplify
a = 6 . . . . . . . . . . . . . length of side BC
Base areaThe area of the right triangle base is ...
A = 1/2bh . . . . . . . . b is the triangle base; h is its height
A = 1/2(6 cm)(8 cm) = 24 cm²
VolumeThe volume of the prism is ...
V = Bh . . . . . . . . . . . . . . . where B is the base area, and h is the height
480 cm³ = (24 cm²)h . . . use known values
h = 20 cm . . . . . . . divide by the coefficient of h
The height of the prism is 20 cm.

Step-by-step explanation:
y = mx + b They gave us the slope of -1. We need to find the y intercept. We will use the x of 9 and the y of 2 to find b. We will plug these numbers in to find b.
y = mx + b
2 = -1(9) + b
2 = -9 + b Add 9 to both sides
11 = b
y = -x +11
Now, plug in 8 for x
y = -1(8) + 11
y = -8 + 11
y = 3
In this case p is 3.

Answers
Answer:

OR
–72 + 32x
Step-by-step explanation:
To use the Distributive Property, just simply follow my steps:
Write the equation:
–8(9 – 4x)
To distribute, multiply the numbers inside the parenthesis by the number outside of the parenthesis SEPARATELY. It should look like this:
(–8 • 9)(–8 • –4x)
(–72)(32x)
Since the 32 is positive, the equation could be written either way:
–72 + 32x
OR
32x – 72
If you want the equation to be fully solved...
Set the equation equal to zero:
32x – 72 = 0
Isolate the variable. Subtract 72 from both sides:
32x – 72 + 72 = 0 + 72
32x = 0 + 72
32x = 72
Divide:
32x/32 = 72/32
x = 9/4 (Improper Fraction Form)
OR
x = 2 (and) 1/4 (Mixed Number Form)
Convert 9/4 to a decimal:
x = 9/4
x = 2.25

So, this is theoretically true if your variable for a side just happened to be "n".
You also put, "The perimeter of a square", A simpler way to put this is
P = s4 or in your case P = n4.
Because this shape is a square all side lengths and angles will be congruent, and therefore will all be the same (which is why we are able to multiply one side by four.)
