Which equation has no solution?
O
-3(x+5)= x - 15 - 2x
-3(x+5) = x - 15 - 4x
O c-3(x+5)= x − 10 - 4x
OD -3(x+5)= x −10+2x
Equation with option B and C has no solution.
What is equation?
When two expressions are connected with the equals sign, a formula known as an equation is created.
Main Body:
A) -3(x+5) = x-15 -2x
⇒ -3x -15 = x-15-2x
⇒ -3x = -x
⇒ -2x= 0
⇒ x = 0, this means it has a solution.
B) -3(x+5) = x- 15 -4x
⇒ -3x -15 = -3x -15
So this equation also has no solution.
as L.H.S cancels out R.H.S completely so this equation has no solution.
C) -3(x+5) = x-10 -4x
⇒ -3x -15 = -3x -10
⇒ -15 ≠ 10
hence the equation with no solution is option b and c.

Abe jogs 1. 8 miles on monday, 1. 3 miles on tuesday, and 1. 2 miles on wednesday. If beth jogs twice as far as abe, how many miles does beth jog?.
Abe jogs 1. 8 miles on Monday, 1. 3 miles on Tuesday, and 1. 2 miles on Wednesday.
Beth will jog 8.6 miles, if she jogs twice as far as Abe.
The answer provided below has been developed in a clear step by step manner.
Step: 1
Given that,
Abe jogs 1.8 miles on Monday, 1.3 miles on Tuesday and 1.2 miles on Wednesday.
So,
Total miles jog by Abe =1.8+1.3+1.2
Step: 2
Adding, we get,
Total miles jog by Abe = 4.3 miles
To find :-
The number of miles Beth jogged.
Step: 3
Since Beth jogs twice as far as Abe, we have,
Number of miles Beth jog = 2×4.3 miles = 8.6 miles
Since Abe jog 4.3 miles in total, Beth will jog (2* 4.3) miles
Hence the answer is, Beth will jog 8.6 miles, if she jogs twice as far as Abe.

The total number of residents that voted in the town election is 5275 votes
Total number of votes received = 2300 votes
Consider the total number of votes in the town election = x
She received 190 more than 2/5 of the total number of votes
2/5 of the total number of votes = (2/5)x
190 more than 2/5 of the total number of votes = (2/5)x + 190
The equation will be
(2/5)x + 190 = 2300
Move 190 to the right hand side of the equation
(2/5)x = 2300 - 190
(2/5)x = 2110

A bird is at the very top of a 35 feet tree. He spies a worm that is 50 feet from the base of the tree. Set up a right triangle picture to find the distance from the bird to the worm.
The distance from the bird to the worm is approximately 61.06 feet.
To set up a right triangle picture to find the distance from the bird to the worm, we can use the given information about the bird's position and the worm's position.
Let's consider the bird at the top of the tree as the highest point of the triangle. The height of the tree, 35 feet, represents the vertical side of the triangle. The worm's position, which is 50 feet from the base of the tree, represents the horizontal side of the triangle.
Now, to find the distance from the bird to the worm, we need to find the hypotenuse of the right triangle, which represents the direct line from the bird to the worm.
By using the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides, we can set up the equation:
h² = 35² + 50²,
where h represents the length of the hypotenuse.
Solving this equation, we find:
h² = 1225 + 2500,
h² = 3725.
Taking the square root of both sides, we get:
h ≈ √3725 ≈ 61.06 feet.

The original size of shampoo = 5.36 ounce
Calculating Percentages:In mathematics, percentages are represented as fractions of 100 in the form of integers or ratios. In most cases, they are indicated by "60%" or 65 percentage and 60% can be expressed as (60/100). They can also be expressed as decimal fractions or simple fractions.
Here are some examples to find percentages,
60% of 200 = (60/100) × 100
50% of n = (50/100) × n
Here given that
There is a bottle of shampoo whose size is 6.7 ounces
It is given that the bottle says it gives 25 percent freer
Let's assume that the original bottle size is x ounce
As we know the bottle gives you a 25% extra
The free amount that can be given on x ounce = [tex]\frac{25}{100} x[/tex] = 0.25x
then the final size of the battle will be = x + 0.25x = 1.25x ounces
As we the bottle size = 6.7 ounces
=> 1.25x = 6.7
=> x = 6.7/1.25 = 5.36
=> x = 5.36 ounce

I need help answering the question…
Find expressions for the slope and x- and y- intercepts for Ax + By = C, where A, B, and C are nonzero integers.
First of all, I do not understand any word in that, so the answer and an explanation with get brainiest.
I gotchu :)
So, the base equation is: ax+by=c
x int is c/a
y int is c/b
and the slope is -a/b
So basically, what I wrote above is how to get each aspect of the line using the standard form formula.
The "nonzero" part means that each integer (the A, B, AND C in the formula above) cannot be 0, as that would mean that everything will end up equaling to 0, which does not create the line. So basically, the answer would be:
x int is c/a
y int is c/b
and the slope is -a/b
^ if you apply these to any standard form, you will get the thing I stated next to it. For example, if the standard form equation is:
5x+6y=5
if you want to find the slope, you will do -a/b, and that will give you -5/6, which is your slope
Hope this helps :)
a) Write an equation for a line in point-slope form that is parallel to the line y=2/3x-5 and passes through the point (3, 4).
b) Explain what would be different in part (a) if you were asked to write an equation for a line that is perpendicular instead of parallel.
Answer: a) y - 4 = 2/3(x) - 2
b) y - 4 = -3/2(x) -2
Step-by-step explanation:
equation of original line: y = 2/3x -5
point on a line parallel to original line: (3,4)
The slope of a line parallel to a given line has the same slope, so the equation of the parallel line (in point-slope form) is:
(y - y1) = 2/3(x - x1)
point (x1, y1) is (3, 4)
plug (3,4) into the equation:
y - 4 = 2/3(x - 3)
y - 4 = 2/3(x) - 2
rewrite in slope-intercept form: y = 2/3(x) + 2
The slope of a line perpendicular to another line is the negative reciprocal of the slope of the first line: - 1/m
Therefore, the slope of the perpendicular line = -3/2
Equation for the perpendicular line is:
y - 4 = -3/2(x) -2
