What properties of equality do you need to use to solve the equation 2.2x-10.5=-1.7? Solve the equation.
Answers
Answer:
C and A are your answers
x = 4.4
Step-by-step explanation:
2.2x - 10.5 = -1.7
First, we use the addition property of equality and add 10.5 to both sides of the equation:
2.2x = 8.8
Then we use the division property of equality and divide both sides by 2.2
x = 4.4

What is the length of each slanted area
Answers
Answer:
15 is the missing length
The required length of the slanted area is 15 yards.
In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.
Pythagorean theorem is defined as to find the unknown side of a right-angled triangle. eg, Two sides of a right-angled triangle are given as 6 cm and 9 cm, then the hypotenuse (the third side) can be calculated using the formula, h² = p2²+ b²; where 'h' is the hypotenuse and 'p' and 'b' are the perpendicular and base.
Here,
let the hypotenuse be h
now applying the Pythagorean theorem,
h² = 9² + 12²
h²= 81 + 144
h² = 225
h = √225
h = 15
Thus, the required length of the slanted area is 15 yards.

Which statement best describes the equation x = 3? A. The equation can not be graphed. B. The equation represents a function, but not a linear function. C. The equation represents a linear function. D. The equation represents a line, but not a linear function.
Answers
Answer:
D
Step-by-step explanation:
x=3 is a vertical line intersecting 3 on the x axis parallel to the y axis. it can be shown a a line, but it is not a function. A function must have 1 y value for every x value. Here there is infinite y values for one x value therefore it is not a function, but a line.
The statement which best describes the equation x=3 is statement which is in option d which tells that the equation describes a line but not a linear function.
What is function?A function is relationship between two or more variables expressed in equal to form. In a function each value of x must have a corresponding v value. The value that is entered into function is domain of the function and the value which we are getting is known as codomain of function.
How to identify statement?The given equation is x=3.
1) This statement says that the equation cannot be graaphed but it is incorrect because the line of this equation will be vertical line parallel to y axis.
2) This statement says that the equation represents a function but not a linear function but it is also not correct because in this equation there are infinite values of y for the value of x which is a contradiction of the definition of function.
3) This statement says that the equation represents a linear function but it is also not correct because the equation is not a function then how it is a linear function.
4) This statement says that the equation represents a line but not a linear function. It is true because the graph of this equation is a line and the equation is not a linear function because it is not a function.
Hence the statement which best describes the equation x=3 is statement which is in option d which tells that the equation describes a line but not a linear function.

m∠A=60,m∠ B=60, m∠C=60°
Step-by-step explanation:
We know that the interior angles of a triangle total up to 180°. We also know that the six angles given are congruent. So we can do 180÷6=30. So each angle equals 30. There are two of these angles at one angle of the whole triangle. So we can do 30×2=60 for each angle of the triangle. Hope this helps :)
