Answer:

5/6

Step-by-step explanation:

Use proportion to find the answer.

prisoha [69]

<u>Answer</u>

$\boxed {64}$

<u>Detailed Explanation </u>

Let's set up a proportion.

$\frac{3}{4.8} = \frac{40}{x}$

Now that we have set up a proportion we would need to cross multiply.

3*x=3x

40*4.8= 192

Solve for x

$3x=192$

$\frac{192}{3} = 64$

Therefore, the answer would be 64.

Answer:

x ≈ 5.89

General Formulas and Concepts:

<u>Pre-Algebra</u>

Equality Properties

<u>Algebra II</u>

Exponential to Logarithmic: $\displaystyle b^m=x \rightarrow log_bx=m$

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

0.77 = log(x)

<u>Step 2: Solve for </u><em><u>x</u></em>

[Equality Property] Raise both sides to the 10th power: $\displaysytle 10^{0.77} = 10^{logx}$
Simplify: $\displaysytle x = 10^{0.77}$
Evaluate: $\displaysytle x = 5.88844$

1/2x + x + 1/5y + y = 32

NeTakaya

(1/2)x + x + (1/5)y + y = 32

(3/2)x + (6/5)y = 32
