How do you determine which variable is independent
and which one is independent?

Answers

Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.

The perimeter of a triangle is 29 millimeters. The length of the first side
is twice the length of the second side. The length of the third side is
5 more than the length of the second side. Find the side lengths of the
triangle. Then classify the triangle by its side lengths.

Answers

Answer:

7.25, 3.625, 18.125

Scalene triangle

Step-by-step explanation:

Turn the lengths into a ratio:

First side twice as long as second side

Third side 5 times as long as second side

First side : Second side  : Third side = 2 : 1 : 5

2 + 1 + 5 = 8

29 / 8 = 3.625

Multiply the ratio by 3.625:

3.625 x 2 = 7.25

3.625 x 1 = 3.625

3.625 x 5 = 18.125

The sides so not follow Pythagoras's theorem a² + b² = c² (c being the largest side, so it is not a right angled triangle  so it is a scalene triangle

A carpenter attaches a piece of plywood with a width of 4 feet and a length of p to another piece of plywood that has a width of 4 feet and a length of 8 feet.


Which expression represents the area of the combined piece of plywood?
A. 4(p + 8)
B. 8(p + 4)
C. 8(p + 8)
D. 4(p + 4)

Answers

A! 4(p + 8)! have a good day

4p + 32, or option C, is the term that depicts the combined plywood piece's area.

What is algebraic Expression?

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

When the two pieces of plywood are attached, the width of the combined piece remains 4 feet.

The length is the sum of the length of the two pieces. So, the area of the combined piece is the product of the length and width.

Length of combined piece = p + 8 feet

Width of combined piece = 4 feet

Therefore, the area of the combined piece of plywood is:

Area = length × width

Area = (p + 8) × 4

Area = 4p + 32

So, the expression that represents the area of the combined piece of plywood is 4p + 32, which is option C.

Answers

The answer is 2.25 because the total was 13.25 and it is asking you how much he paid for the ham. So you would first subtract 2 from 13.25 which gives you 11.25 and then divide by 5 and it will give you the answer which is 2.25

75+11x+-2
Please give an explanation and answer

Answers

7 Simplifying
75 = 11x + -2

Reorder the terms:
75 = -2 + 11x

Solving
75 = -2 + 11x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-11x' to each side of the equation.
75 + -11x = -2 + 11x + -11x

Combine like terms: 11x + -11x = 0
75 + -11x = -2 + 0
75 + -11x = -2

Add '-75' to each side of the equation.
75 + -75 + -11x = -2 + -75

Combine like terms: 75 + -75 = 0
0 + -11x = -2 + -75
-11x = -2 + -75

Combine like terms: -2 + -75 = -77
-11x = -77

Divide each side by '-11'.
x = 7

Simplifying
x = 7
