What is the solution to this equation?
6(x-5)=4x+20
Answer:
x = 25Step-by-step explanation:
What is the solution to this equation?
6 * (x - 5) = 4x + 20
6x - 30 = 4x + 20
2x = 20 + 30
2x = 50
x = 50 : 2
x = 25
-------------------
check
6 * ( 25 - 5) = 4 * 25 + 20
6 * 20 = 100 + 20
120 = 120
the answer is good
Answer:
x=25Step-by-step explanation:
6(x-5) 4x+20
Distribute.
6x-30 = 4x+20
Subtract 4x from each side.
6x-4x-30 = 4x-4x+20
Simplify.
2x-30=20
Add 30 to both sides.
2x-30+30 = 20+30
Simplify.
2x = 50
Divide both sides by 2
2x/2 = 50/2
Simplify
x = 25
So, x = 25!

Soil sells for 8 1/4 cents per pound. How much would you save if you bought a 100- pound sack for $7.45?
Answer:
$0.80
Step-by-step explanation:
If the 100 pounds was bought separately (of course in real life you will probably not)
= 100 pounds x $0.0825/pound
= $8.25
As you can see it will cost more than if you buy a 100 pound sack.
Cost Difference = $8.25 - $7.45 = $0.80
That means you will save $0.80 from it.
There will be a profit of $0.8 if the soil is bought for $7.45 for 100- pound sack and sold for 8 1/4 cents per pound.
What is Multiplication?Multiplication in mathematics is the process of adding a number repeatedly up to the times of another number. If two numbers, namely a and b are multiplied, this is denoted by a × b. This means that 'a' is added repeatedly to itself up to b times or b is added repeatedly up to 'a' times.
Amount got for 1 pound soil after selling = 8 [tex]\frac{1}{4}[/tex] cents
= 33/4 cents
= 8.25 cents
= 8.25 / 100 dollars
= 0.0825 dollars
For 100 - pound sack, amount got after selling = 0.0825 × 100
= 8.25 dollars
Cost for 100 - pound sack = $7.45
Profit = $8.25 - $7.45
= $0.8
$0.8 will be saved if you bought a 100- pound sack for $7.45.

What is a quadratic equation?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:

(x + 1)² - 3 = 0
(x + 1)² = 3

The diagonal of a rhombus is 24m and 10m. Find the perimeter.
Answer:
52m
Step-by-step explanation:
rhombus
its like a slanted square
all its 4 sides are equal like a square
both pairs of opposite sides are parallel
when the diagonals criss cross they make 4 triangles inside
the sides of the rhombus become the hypotenuse of a triangles inside
if the diagonal is 24 and 10 then
its radius is 12 and 5
the sides of the rhombus become the hypotenuse of a triangle that have the sides 12 and 5
hypotenuse of a triangle that has the sides 12 and 5 is
13
(its a special triangle: its a 5, 12, 13 right triangle)

Function g can be thought of as a translated (shifted) version of f(x)=x^2
Answer:
g(x)=x^2 -6x +5
Step-by-step explanation:
Answer:
g(x) = (x - 3)² - 4
Step-by-step explanation:
When values are directly added to the "x" variable (usually inside of parentheses), the function shifts to the left that many units.
When values are directly subtracted from the "x" variable, the function shifts to the right that many units.
When values are added to an overall function, the function shifts upwards that many units.
When a value is subtracted from an overall function, the function shifts downwards that many units.
We can determine how the function has been translated by looking at the changed position of the vertex (the lowest point of the line).
As you can see, the new vertex now lies on x = 3 rather than x = 0.This means that there should be a -3 directly next to the "x" variable in the new function.
The new vertex also now lies on y = -4 rather than y = 0. Therefore, there should be a -4 added to the overall equation.
These changes make the new function:
g(x) = (x - 3)² - 4

Your image attached has not sufficient criteria for Brainly users to answer. We will assume for now that you are asking what the line is equal to. This question will be deleted eventually due to Brainly ToS most likely
We note that this line is not linear, or squared. This means it might be cubical.
If it is cubical the line must be a variant of
f(x)=[tex]x^{3}[/tex].
However f(x)=[tex]x^{3}[/tex] points the opposite direction so we must make it negative.
We also noticed we had to stretch it, so we had to add a fraction.
Your answer is f(x)=[tex]-\frac{1}{8} x^{3}[/tex]

A force F = (4x i +3y) N acts on an object as the object moves in the x direction from the origin to x =5.00 m. Find the work done.
The work done is 100 + 15y Joules
How to find the work doneThe formula for determining the work done is given as;
Work done = force × distance
We have;
Force = (4x + 3y)
Distance = x = 5.00m
Work done = (4x + 3y) × x
Work done = 4x^ 2 + 3xy
Let's substitute the value of 'x'
Work done = 4 × 5 × 5 + 3 × 5 × y
