what number is halfway between 8.270 and 8.280? The answer is 8.275 hope this helps
Answer:
8.275
Step-by-step explanation:
8.280 - 8.270 = 0.010
0.010/2 = 0.005
8.270 + 0.005 = 8.275
The number halfway between 8.270 and 8.280 is 8.275.
What is Arithmetic?The study and use of numbers, their connections, and mathematical observations are topics covered by the area of mathematics known as arithmetic. The fundamental ideas in number theory, measurement, and calculation are frequently referred to as "arithmetic" (which is derived from the Greek word "arithmos," "number") (that is, the processes of addition, subtraction, multiplication, division, raising to powers, and extraction of roots).
As per the given data:
We have to find the number which is halfway between 8.270 and 8.280.
For finding the number, we can calculate the difference between 8.270 and 8.280 and then divide it by two now we can add the obtained number into 8.270 to get the number.
[tex]\frac{8.280 - 8.270}{2}[/tex]
= [tex]\frac{0.010}{2}[/tex]
= [tex]0.005[/tex]
The number halfway between 8.270 and 8.280:
8.270 + 0.005
= 8.275
Hence, the number halfway between 8.270 and 8.280 is 8.275.

How many solutions does 3(x + 5) – 3 = 2(3x + 1) – 3x have? Show your work.
Answer: There are no solution
Step 1: Simplify both sides of the equation.
3(x+5)−3=2(3x+1)−3x
(3)(x)+(3)(5)+−3=(2)(3x)+(2)(1)+−3x(Distribute)
3x+15+−3=6x+2+−3x
(3x)+(15+−3)=(6x+−3x)+(2)(Combine Like Terms)
3x+12=3x+2
3x+12=3x+2
Step 2: Subtract 3x from both sides.
3x+12−3x=3x+2−3x
12=2
Step 3: Subtract 12 from both sides.
12−12=2−12
0=−10
After solving the equation, the value obtained for x is 0, which means that there is no solution for the equation.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given equation mentioned in the question,
3(x + 5) - 3 = 2(3x + 1) - 3x
Let's simplify the equation first,
3x + 15 - 3 = 6x + 2 - 3x
Now, rearrange the equation with similar terms on each side,
3x + 3x - 6x = 3 +2 - 15
0 = -10, then there is no solution.

Which equation represents a line with a slope of -6/5
and a y-intercept of 1?
Answer:
y = -6/5x + 1
Step-by-step explanation:
The equation that represents a line with a slope of -6/5 and a y-intercept of 1 is y = -6/5x + 1
How to determine the equation?The given parameters are:
Slope, m = -6/5y-intercept = 1Let the variable of the equation be x.
A linear equation is represented as:
y = Slope * x + y-intercept
So, we have:
y = -6/5 * x + 1
Evaluate
y = -6/5x + 1
Hence, the equation is y = -6/5x + 1

Answer:
(y - 4)/(y + 5)Step-by-step explanation:
Simplify by factoring both trinomials:
(y^2 - y - 12)/ (y^2 +8y + 15) = (y - 4)(y + 3) /(y + 5)(y + 3) =(y - 4)/(y + 5)Felix surrounds a 12 in. by 8 in. photo with a frame that is x inches wide. Which quadratic function represents the combined area A of the picture and the frame?
A. A(x) = x^2 + 20x + 96
B. A(x) = x^2 + 40x + 96
C. A(x) = 4x^2 + 20x + 96
D. A(x) = 4x^2 + 40x + 96
Answer:
D: A(x) = 4x² + 40x + 96
Step-by-step explanation:
Dimensions of photo is;
Length; L = 12 inches
Width; W = 8 inches
Now, this picture is surrounded by a frame that is "x" inches wide. Thus, new dimensions are;
L_new = 12 + x + x = 2x + 12
W_new = 8 + x + x = 2x + 8
New area is;
A_new = (2x + 12) × (2x + 8)
A_new = 4x² + 24x + 16x + 96
A_new = 4x² + 40x + 96

What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
g(x) = 10 - 2x
For x = 7,
g(7) = 10 - 2 x 7
g(7) = 10 - 14
g(7) = -4
Thus,
g(7) = -4.
