What does 6x − 9 = 45 equal?
Answer:
9
Step-by-step explanation:
Add nine to both sides:
[tex]6x = 54[/tex]
Divide by six:
[tex] \frac{6x = 54}{6} [/tex]
[tex]x = 9[/tex]
Answer:
x = 9
Step-by-step explanation:
Add 9 to each side to begin simplifying. It should now look like this: 6x = 54Now, divide each side by 6 to find the value of x. It should look like this: x = 9I hope this helps!

Answer:
140°
Step-by-step explanation:
[tex] \because m\widehat{BG} = 360\degree - m\widehat{GCB} \\

\because m\widehat{BGD} = m\widehat{BG}
+m\widehat{GD}\\

Answer:
6.25%
Step-by-step explanation:
The probability of landing on B once is 25%.
So you multiply 25% by 25%.
0.25×0.25
The answer is 0.0625.
Converting back to %, its 6.25%.

What is the leading coefficient of the polynomial: 5-3x+4x^2
Answer:
4
Step-by-step explanation:
5-3x+4x^2
Write the terms from highest power to smallest power
4x^2 -3x +5
The leading coefficient is the term in front of the highest power
4
Answer:
4
Step-by-step explanation:
The first step here is to rearrange the terms of this polynomial in descending order: x^2, then x, then x^0 (nothing that x^0 = 1):
4x^2 - 3x + 5
The "leading coefficient of the polynomial) is the coefficient of the highest x power, which here is x^2: 4.

Pls help I’ll mark Brainliest!! Which mapping represents a function?
Answer:
Mapping C represents a function.
To be a function, there must be one and only one y value (output) for every input value (x value).
Mapping C matches this criteria, thus it is a function.

PLEASE HELP! I WILL GIVE BRAINLIEST (8.02 MC) A pair of equations is shown below: y = 7x − 9 y = 3x − 1 Part A: In your own words, explain how you can solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations. (6 points) Part B: What is the solution to the pair of equations? (4 points)
Answer:
Step-by-step explanation:
slope intercept form: y=mx+b
m= slope
b= y-intercept
y= 7x - 9
slope= 7
y-int.= -9
y= 3x - 1
slope 3
y-int.= -1
7x-9 = 3x-1
Add 9 to both sides: 7x = 3x +8
Subtract 3 from both sides: 4x = 8
Divide by 4 on both sides: x =2
Substitute 8 into the equation: y = 3(2) -1
y = 5
Solution: (2,5)

Solve for x. 23x +2=15x+48x+6
Answer:
[tex]x = - \frac{1}{10} [/tex]Step-by-step explanation:
23x +2 = 15x+48x+6
To solve for x group like terms
That's
Send the constants to the right side of the equation and those with variables to the left side
We have
23x - 15x - 48x = 6 - 2
Simplify
- 40x = 4
Divide both sides by -40
[tex] \frac{ - 40x}{ - 40} = \frac{4}{ - 40} [/tex]We have the final answer as
[tex]x = - \frac{1}{10} [/tex]Hope this helps you
If a square has a side of length 3, then it’s area is 9. This square has a side of length 3, so it’s area is 9. Is it valid or invalid?
Answer:
Yes it is valid
Step-by-step explanation:
A square is a geometric shape which is also known as a Quadrilateral. This means that it has 4 sides.
For a square, it's 4 sides are equal to one another or we can put it in other words as the length of the 4 sides of a square are congruent to one another.
From the above question, we are asked that:
"If a square has a side length of 3, it's area is 9. Is it valid or invalid?"
The above statement is valid. This is because, the formula for the Area of a Square is given as
L × L = L²
Where L = Side length = 3
Area = 3 × 3 = 3²
Area = 9
Therefore, the statement is valid.
PLEASE HELP ASAP!! (: One link below. I WILL NAME BRAINLIEST!! 30 points (: Make sure to show ur work. One who shows work and gets correct, gets title of Brainliest!! (: Convert the percentages to a fraction, and then convert the fraction to a mixed number or a whole number!
Answer:
[tex]\boxed{\sf{view \: explanation}}[/tex]
Step-by-step explanation:
To convert percentages into a fraction, divide the value by 100.
[tex]\displaystyle 800\% =\frac{800}{100} =8[/tex]
[tex]\displaystyle 375\% = \frac{375}{100} =\frac{15}{4} =3\frac{3}{4}[/tex]
[tex]\displaystyle 240\% = \frac{240}{100} =\frac{12}{5} =2\frac{2}{5}[/tex]
Answer:
see below
Step-by-step explanation:
To change a percent to a fraction, divide by 100 and simplify
800% = 800/100
Dividing by 100
= 8/1
=8
375% = 375/100
Dividing by 25
=15/4
Changing to a mixed number
4 goes into 14 3 times with 3 left over
3 3/4
240% = 240/100
Dividing by 20
=12/5
Changing to a mixed number
5 goes into 12 2 times with 2 left over
= 2 2/5

the area of a trapezium is 14.7cmsquare. if the parallel sides are 5.3cm and 3.1cm long,find the perpendicular distance between them
The perpendicular distance of the trapezoid is 3.5 cm
How to determine the perpendicular distance?The given parameters are:
Parallel sides = 5.3 cm and 3.1 cmArea = 14.7 square cmThe area of a trapezoid is:
Area = 0.5 * (Sum of parallel sides) * perpendicular distance
So, we have:
14.7 = 0.5 *(5.3 + 3.1) * perpendicular distance
Evaluate
Perpendicular distance = 3.5
Hence, the perpendicular distance of the trapezoid is 3.5 cm

The diameter of a wheel of a car is 30cm. If the car travels at an average speed of 13.2m/s, find the number of revolutions made by the wheel per hour, giving your answer correct to the nearest whole number.
Answer:
Approximately [tex]50420[/tex] revolutions (rounded to the nearest whole number.)
Step-by-step explanation:
Convert the diameter of this wheel to meters: [tex]d = 30\; \rm cm = 0.30\; \rm m[/tex].
Circumference of this wheel:
[tex]\pi \, d = \pi \times 0.30\; \rm m \approx 0.942\; \rm m[/tex].
Distance travelled in one hour:
[tex]\begin{aligned}v \cdot t &= 13.2 \; \rm m \cdot s^{-1} \times 3600\; \rm s \\ &= 47520\; \rm m\end{aligned}[/tex].
Number of revolutions required for covering that distance:
[tex]\displaystyle \frac{47520\; \rm m}{(\pi \times 0.30\; \rm m)} \approx 50420[/tex].

Write an expression in simplified form for the area of each rectangle. Width: 7 Length: 5n-9
Answer:
35n - 63
Step-by-step explanation:
The area of a rectangle is given by
A = l*w where l is the length and w is the width
A = 7(5n-9)
Distribute
A = 35n - 63
Area of rectangle = Length * Width
Length is 5n-9
Width is 7
⇛Area = 5n-9(7)
⇛Area = 33n - 63
