solve this equation 3\5(x-10)=18-4x-1
Simplify using distributive property. Which number can be distributed across two terms inside parentheses?
Answer choices:
-10
3\5
x
3/5 is the number which can be distributed across two terms inside parentheses
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 3/5 (x-10) = 18-4x-1
According to the distributive property, multiplying the sum of two or more addends by a number produces the same result as when each addend is multiplied individually by the number and the products are added together.
To solve the above equation we have to distribute 3/5 on LHS
3/5x-30/5 = 18-4x-1
3/5x-6 = 17-4x
Hence, 3/5 is the number which can be distributed across two terms inside parentheses

A wire is first bent into the shape of a rectangle with width 5in and length 13in. Then the wire is unbent and reshaped into a triangle. If each side of the triangle has equal length, what is this length?
Length of each side of a triangle with equal measurements is equals to [tex]12in[/tex].
What is perimeter?" Perimeter is defined as the total length around the boundary of any two dimensional geomertic shape."
Formula used
Perimeter of a rectangle [tex]= 2 ( L + W)[/tex]
[tex]L =[/tex] length of the rectangle
[tex]W =[/tex] Width of the rectangle
Perimeter of a triangle with equal length [tex]= 3s[/tex]
[tex]s =[/tex] side length of a triangle
According to the question,
Given,
Length of a rectangle [tex]'L'= 13 in[/tex]
Width of a rectangle [tex]'W' = 5 in[/tex]
Substitute the value in the formula we get,
Perimeter of a rectangle [tex]= 2( 13 + 5)[/tex]
[tex]= 36 in[/tex]
Substitute the value in the perimeter of a triangle with equal side length,
[tex]3s = 36 in\\\\\implies s = \frac{36}{3} \\\\\implies s = 12in[/tex]
Hence, Length of each side of a triangle with equal measurements is equals to [tex]12in[/tex].

A student must have an average (the mean) on five tests that is greater than or equal to 80% but less than 90% to receive a final grade of
b. devon's grades on the first four tests were 92%, 82%, 88%, and 92%. what range of grades on the fifth test would give him a b in the course?
The requried, Devon needs to score between 46% and 95% on the fifth test to receive a final grade of a B in the course.
To find the range of grades Devon needs on the fifth test to receive a final grade of a B (between 80% and 90% inclusive), we need to consider the average of all five tests.
Let's denote the grade on the fifth test as "x" (in percentage).
The average of the five tests will be:
Average = (92% + 82% + 88% + 92% + x) / 5
To achieve a final grade of a B, the average must be greater than or equal to 80% but less than 90%:
80% ≤ Average < 90%
Now, substitute the given grades and the variable "x" into the average equation:
(92% + 82% + 88% + 92% + x) / 5 ≥ 80%
(92 + 82 + 88 + 92 + x) / 5 ≥ 80
(354 + x) / 5 ≥ 80
354 + x ≥ 400
x ≥ 400 - 354
x ≥ 46
Now, for the upper limit:
(92 + 82 + 88 + 92 + x) / 5 < 90
(354 + x) / 5 < 90
354 + x < 450
x < 450 - 354
x < 96
So, Devon needs to score between 46% and 95% on the fifth test to receive a final grade of a B in the course.

Devon must score between 46% and 91% on his fifth test to achieve a B average in the course.
Explanation:To determine the range of grades on the fifth test that would give Devon a final grade of B, we need to calculate the average of the five test scores. For an average to fall between 80% and 90%, the total sum of the five test grades must be between 400% and 449%, since 5 tests × 80% = 400% and 5 tests × 89% (just below 90%) = 445%. Devon's current grades add up to 92% + 82% + 88% + 92% = 354%. Therefore, to achieve a B, his fifth test score needs to be between 400% - 354% = 46% and 445% - 354% = 91%.

The altitude of an equilateral triangle is 9 inches. Find the perimeter of the triangle in inches.
The perimeter of the triangle will be 31.18 inches.
what is perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape.
If we draw a perpendicular line from one of the vertices of the triangle we get 2 right angled triangles each with altitude 9 ins and vertex angle = 30 degrees. So:-
[tex]Cos 30 =\dfrac{ 9} {h}[/tex]
where h = one of the sides of the equilateral triangle
[tex]h = \dfrac{9 }{ cos 30} = 10.392 \ inches[/tex]
Therefore the perimeter of the triangle =
[tex]3 \times 10.392 = 31.1769 \ inches[/tex]

We are to give a counterexample for this.
Let us consider that

A circle with a radius of inches has a central angle of 0.25 radians that intercepts an arc of inches.
Answer:
Step-by-step explanation:
Given that there is a circle of .... inches with central angle 0.25 inches
by formula we have arc = radius *central angle in radians
The radii are given three options as 10,20,4 and corresponding arcs as
25,5, 16 inches.
By matching we find that 10(0.25) not equals 25
But 20(0.25) = 5 inches
Also 4(0.25) not equals 16 inches
Hence correct answer is radius = 20 and central arc = 5 inches
