3. Simplify 3 x g x 5 x h
Answer:
3 into g into 5 into h
in this we will group the term 3 and 5 together and then the g and h
so the answer will be 3 into 5 into g into h = 15gh
The expression 3 × g × 5 × h is in the simplified form of 15gh.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
It is also known as the product. If the object n is given to m times then we just simply multiply them.
The expression is given below.
⇒ 3 × g × 5 × h
Simplify the expression, then we have
⇒ 3 × g × 5 × h
⇒ 15gh

Write an equation of the line that passes through point P and is parallel to the line with the given equation. P(3,5); y=2x-6
Answer:
y = -(5/2)x + 3 is a line perpendicular to y = (2/5)x + 2. This line is also perpendicular to y = (2/5)x + 9 because it has the same slope.
Step-by-step explanation:
A) So the line you are given is written in slope intercept form y = mx + b meaning that the slope of the line is m = 2/5 and the intercept b = 9 (so the line hits the y axis at 0,9). A line that is parallel has to have the same slope so we know our m is the same. So we have y = (2/5)x + b. We need b. It passes (0, 2) since the x coordinate is 0 you know the y intercept is 2 but you can verify this using the point slope formula:
y - y1 = m(x - x1) plug in values
y - 2 = (2/5)(x - 0) now simplify
y - 2 = (2.5)x last solve
y = (2/5)x + 2 see how when the x coordinate is 0 you can automatically use the point slope intercept formula? Neato!
B) Now we want a line perpendicular to y = (2/5)x + 2 and that passes through 0,3. What are the properties of a line perpendicular to a line of the form y = mx + b and passes through (0, 3)? We know that the slope of this new line will be the reciprocal and have the opposite sign of m. So the new slope we will call it mnew = -(1/m) so plug in for m and you get mnew = -(1/[2/5]) if you simplify you get that the mnew = -(5/2). So we have half of our equation for the perpendicular: y = -(5/2)x + b. If you look at (0, 3) you see that the y intercept is 3 so b = 3. So:
The equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, we need to find the equation of a line passing through the point (3, 5) and is parallel to y = 2x-6,
Comparing the given equation with the general equation of line y = mx+c
m = 2 (the slope)
We know that the two parallel lines have equal slope.
Therefore, the required equation is =
y = 2x+c
To find the value of c, put x = 3 and y = 5,
5 = 2(3) + c
c = -1
Therefore,
The required equation is =
y = 2x-1
Hence, the equation of the line that passes through given point and is parallel to the line with the given is y = 2x-1

Answer:
[tex]\frac{A-2wh}{2(w+h)}=l[/tex]
Step-by-step explanation:
We have to find the formula for the value of 'l'.
So, we will isolate 'l' on one side of the formula.
A = 2lw + 2lh + 2wh
A = 2l(w + h) + 2wh
A - 2wh = 2l(w + h) + 2wh - 2wh
A - 2wh = 2l(w + h)
[tex]\frac{A-2wh}{2(w+h)}=\frac{2l(w+h)}{2(w+h)}[/tex]
[tex]\frac{A-2wh}{2(w+h)}=l[/tex]
Therefore, formula for 'l' will be,

The ∠DCO will be 2·x, 69° is the sum of ∠DCO and x° is x = 23°
What is a circle?A curving line makes up the form of a circle. It is spherical, and every point along the curving line is equally spaced first from the center. Due to its multiple nature, this form is flat.
Points on the circle is A, B, C, and D
Straight lines present are AOBE and DCE
Segment CO = Segment CE
∠AOD = 69°
∠CEO = x°
∠OCD = ∠ODC as this is an isosceles triangle
an exterior angle of a triangle can be determined as
69° = ∠x° + ∠ODC
Because of the Angle sum property of a triangle
∠DOC = 180 - 2×∠ODC
Angles added together on a linear fashion are supplementary.
180 - 2×∠ODC + x° + 69° = 180°
x° + 69° - 2×∠ODC = 0
A triangle's exterior angle is equal to the product of its diagonal internal angles
∠ODC = 2·x°
69° = x° + ∠ODC = x° + 2·x° = 3·x°
69° = 3·x°
x = 69° ÷ 3
x = 23°

Please help! Marking brainliest if correct.
Answer:
110 degrees
Step-by-step explanation:
Because these angles are vertical, 5x+15=8x-42. thus, 15=3x-42, 3x=57, and x=19. 5x+15=5(19) +15=110. So, m<CDE=110 degrees.
Answer:
110°
Step-by-step explanation:
Since CDE and FDG are vertical, they are congruent, so:
5x + 15 = 8x - 42
Solve the equation for x
57 = 3x
19 = x
Then solve for one of the angles (I chose CDE but FDG would also work)
5(19)+15
95 + 15
110

Suppose you asked 100 commuters how much they spend each year and obtained a mean of $167 spent on transportation and a standard deviation of $40. Using the 2 SE rule of thumb, calculate a 95% confidence interval for the mean and select the values that come closest to those that would fill the spaces in the following interpretation: we can be 95% confident that the mean amount of money spent on transportation lies between _____ and _____ .
Answer:
The correct answer is "$159 and $175".
Step-by-step explanation:
The give values are:
Mean,
= $167
Standard deviation,
[tex]\sigma[/tex] = $40
Number of commuters,
n = 100
Now,
⇒ [tex]SE=\frac{\sigma}{\sqrt{n} }[/tex]
On putting the given values, we get
⇒ [tex]=\frac{40}{\sqrt{100} }[/tex]
⇒ [tex]=\frac{40}{10}[/tex]
⇒ [tex]=4[/tex]
By using the 2 SE rule of thumb, we get
= [tex]$(167 - 2\times 4)[/tex]
= [tex]167-8[/tex]
= [tex]159[/tex] ($)
Or,
= [tex](167 + 2\times 4)[/tex]
= [tex]167+8[/tex]
= [tex]175[/tex] ($)
