Answer:

4 kg of sugar would contain $1.2 \times 10^9$ crystals.

Step-by-step explanation:

Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.

Thus, set up a proportion as follows:

3 kg : 9 × 10⁸ = 4 kg : x

$\frac{3}{9 \times 10^8} = \frac{4}{x}$

Solve for x. Cross multiply.

$3 \times x = 9 \times 10^8 \times 4$

$3x = 36 \times 10^8$

$3x = 3.6 \times 10^9$

Divide both sides by 3

$\frac{3x}{3} = \frac{3.6 \times 10^9}{3}$

$x = 1.2 \times 10^9$

4 kg of sugar would contain $1.2 \times 10^9$ crystals.

Identify the parts of the following algebraic expression. -8z 1 2 y - 7. 7 Term: Variable: Coefficient: Constant:.

Harlamova29_29 [7]

The variables are unknown, coefficients are numbers in multiplication with those unknown variables and constants are solo standing numbers.

Thus, we have:

Variables = z and y

Coefficients = -8 and 12

Constant = -7.7

<h2>Given that:</h2>

The algebraic expression $-8z + 12y - 7.7$

Variables, coefficients and constants in the given algebraic expression.

<h3>What is algebraic expression?</h3>

Its a mathematical expression built up from integer constants, variables and algebraic operations.

<h3>What is variable?</h3>

Those symbols or placeholders who may change( vary ) are called variables.

<h3>What are coefficients?</h3>

Those numbers which are in multiplication with variables in the given expression are called coefficients.

<h3>What are constants?</h3>

Constants are numbers who are not associated in multiplication( or division) with variables in given expression.

Thus, for given expression -8z + 12y - 7.7,

we have:

z and y as variables

-8 is coefficient of z

12 is coefficient of y

-7.7 is constant.
