The value of x in the given equation -9x+7= -6x + 37 will be -10.
What is the equation?An equation can be defined in numerous ways. Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
Given the equation
-9x+7= -6x + 37
-9x + 6x = 37 - 7
-3x = 30
x = -30/3
x = -10
Hence correct answer will be -10.

Raphael's neighborhood kid's pool is shaped like a square with an area of 120ft2. What is the approximate side length of the pool? (Between which two whole numbers)
Answer:
The approximate side length is between 10 ft and 11 ft
Step-by-step explanation:
Here, we are interested in calculating the approximate length of the square shaped pool.
Mathematically, the area of a square is s^2 where s represents the length of its side
in this case; s^2 = 120
s = √120
s = 10.95 approximately
So the length of the side of the square is between 10 and 11 ft
If x power 2 - x- 6 and x power 2+3x- 18 have a common factor ( x -a ) then find the value of a
Answer:
a = 3
Step-by-step explanation:
Factorise both expressions\x² - x - 6 = (x - 3)(x + 2)
x² + 3x - 18 = (x - 3)(x + 6)
Thus both expressions have a common factor of (x - 3) , thus
a = 3

convert 0.06 yards to inches
Answer:
0.06 yards = 2.16 inches
Step-by-step explanation:
1 yard = 36 inches
0.06 yards = 0.06*36 = 2.16 inches
Answer:
2.16 inches
Step-by-step explanation:
We know that 1 yard has 36 inches. With this, we can use dimensional analysis to convert 0.06 yards to inches. (0.06 yd/1) · (36 in/1 yd) You can cancel out the yards and once you've done that, you will you answer in inches. Now multiply 36 × 0.06 = 2.16 You got your answer!! 2.16 inches!the total amount of water a tank can hold is 14 1/4 gallons. Rual wants to find out many 1 1/4 gallon buckets of water can be used to fill the tank. Which expressions could be used to represent this scenario?
Step-by-step explanation:
the volume of gallon is 14 1/4=57/4
the volume of bucket is 1 1/4=5/4
Divide 57/4÷5/4
[tex] \frac{57}{4} \div \frac{5}{4} \\ \\ \frac{57}{4} \times \frac{4}{5} \\ \frac{57}{5} = 11.4 [/tex]
Space shuttle Max is one of the extreme rides in enchanted kingdom. The first of its kind in the country, this roller coaster ride inverts its riders six times. If during one of its operations, a 53 kg boy experiences a net force of 1800N at the bottom of its rollercoaster loop, how fast would he be accelerating at this location?
Answer:
[tex]Acceleration = 33.96ms^{-2}[/tex]
Step-by-step explanation:
Given
[tex]Mass = 53kg[/tex]
[tex]Force = 1800N[/tex]
Required
Determine the acceleration
The relationship between force, mass and acceleration is:
[tex]Force = Mass * Acceleration[/tex]
Substitute values for Force and Mass
[tex]1800 = 53 * Acceleration[/tex]
Solve for Acceleration
[tex]Acceleration = 1800/53[/tex]
[tex]Acceleration = 33.9622641509[/tex]
[tex]Acceleration = 33.96ms^{-2}[/tex]---- Approximated
Riley is going to buy a television for $444.50 plus tax. The sales tax is 6.5%.
How much will the television cost with tax included?
Answer: 473.39
Step-by-step explanation:
444.50 + 0.065*444.50 = (1 + 0.065)*444.50 = 1.065*444.50 = $473.39
Based on the information given the television cost with tax included is $473.39.
Using this formula
Cost=Principal+(Principal× Sales tax)
Where:
Principal=$444.50
Sales tax=6.5%
Let plug in the formula
Cost=$444.50+($444.50×6.5%)
Cost=$444.50+$28.89
Cost=$473.39
Inconclusion the television cost with tax included is $473.39.

Answer:
48
Step-by-step explanation:
Given the equation :
2x + 12
The best answer is 48 because when you measure the angle its equal to 48.
And we can use the equation:
2x + 12 = 48
2x + 12 - 12 = 48 -12
2x= 36
2x/ 2=36/2
x= 18
Thus we can prove abx is 48 by use of the equation and the measuting.

1 3/4 , square root of pi , 1.71 , 16/9
Answer: 1.71, square root of pi, 16/9 and 13/4
Step-by-step explanation: first you need to make all of them into decimals in order to arrange them so, 13/4 = 3.25, square root of pi= 1.772, 1.71 = 1.71( already a decimal) and 16.9 = 1.777.
Once you have written them all in decimals you can now arrange them from least to greatest.

An electric company charges $0.15 for each kilowatt-hour of electricity. If your electric bill is $67.50, how many kilowatt- hours of electricity did you use?
Answer:
450 kilo watt hour of electricity was used
Step-by-step explanation:
Here, we are interested in calculating the kilowatt-hour of electricity used.
From the question, we are told that the bill is $67.50 and the cost of 1 kilo watt hour is $0.15
So to know the amount of kilowatt hours of electricity used, we will simply divide the bill by the charge per 1 kwh
Mathematically that would be 67.5/0.15 = 450
