Simplifying 10x + -2x + 6 = 3x + -9
Reorder the terms: 6 + 10x + -2x = 3x + -9
Combine like terms: 10x + -2x = 8x 6 + 8x = 3x + -9
Reorder the terms: 6 + 8x = -9 + 3x
Solving 6 + 8x = -9 + 3x
Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation. 6 + 8x + -3x = -9 + 3x + -3x
Combine like terms: 8x + -3x = 5x 6 + 5x = -9 + 3x + -3x
Combine like terms: 3x + -3x = 0 6 + 5x = -9 + 0 6 + 5x = -9
Add '-6' to each side of the equation. 6 + -6 + 5x = -9 + -6
Combine like terms: 6 + -6 = 0 0 + 5x = -9 + -6 5x = -9 + -6
Combine like terms: -9 + -6 = -15 5x = -15
Divide each side by '5'. x = -3
Simplifying x = -3

Use the following information to answer all parts of question 3.3a: What is the area of the triangle? (Area of triangle = 1/2*b*

Anit [1.1K]

Answer:

See below ~

Step-by-step explanation:

3a : Area of the triangle

A = 1/2bh
A = 1/2 x 10 x 8
A = 5 x 8
A = 40 m²

3b : Area of the semicircle

Finding the radius (equal to 1/2 of the triangle hypotenuse)
Apply Pythagorean Theorem here
√8² + 10² = d
√64 + 100 = d
d = √164
d = 2√41
r = √41

A = πr²/2
A = 3.14 x (√41)² / 2
A = 1.57 x 41
A = 64.4 m² (nearest tenth)

I need to know which one is an expression, equation, and inequality

grin007 [14]

Answer/Step-by-step explanation:

An expression is a series of number without any signs so expression would be the first one.

Inequality would be when they do a sign like > or <, etc. so it would be the 2nd one.

Equation would be when they have an equal sign which would be the 3rd one.

Simple Ex.

Expression : 2 + 66 / 11 - 3 x 2

Inequality : g + h > f

Expression : 4j - 3 = j

Hope this helps :)

The volume of a cylinder is 176 cm and its height is 11 cm,

Mekhanik [1.2K]

Answer:

4cm

Step-by-step explanation:

The volume of the cylinder is the product of the area of the base and the height. In mathematical equation, this can be written as,

V = πr²h

where V is volume, r is the radius, and h is the height.

Substituting the known values from the given,

176π cm³ = πr²(11 cm)
