Answer:

147mm

Step-by-step explanation:

volume of the block:

256×152×81

3,151,872 mm³

volume of a cube: side³

side³ = 3,151,872

side = 3,151,872^⅓

side = 146.618753863

approximately 147 mm

It would be y=x-4 because y is 4 take away x. For example, x is 0 and y is -4, therefore -4 has been taken away.

Hope this makes sense and I hope I’ve helped.

Have a great day :)

The sum of ages of three brothers is 79. If James I’d half as old as Brandon and Marshall is 11 years younger then Brandon how o
scZoUnD [109]

Answer:

The youngest brother is <em><u>James</u></em> and his age is <em><u>18 Years</u></em>.

Step wise explaination:

Lets suppose,

age of James = <em>x</em>

age of Brandon = <em>2x</em>

age of Marshall = <em>2x - 11</em>

The sum of ages of three brothers = <em>79</em>

<em>now,</em>

finding the value of x,

x + 2x + 2x - 11 = <em>79</em>

or, 5x - 11 = <em>79</em>

or, 5x = <em>79 + 11</em>

or, 5x = <em>90</em>

or, x = <em><u>90</u></em>

<em> 5</em>

so, x = <em><u>18</u></em>.

<em>Then,</em>

age of James = <em><u>18</u></em>.

age of Brandon = <em>2×</em><em>1</em><em>8</em> = <u><em>3</em><em>6</em></u>.

age of Marshall = <em>(</em><em>2</em><em>×</em><em>1</em><em>8</em><em>)</em><em> - 11</em><em> </em><em>=</em><em> </em><u><em>2</em><em>5</em></u><em><u>.</u></em>

<em>There</em><em>for</em><em>e</em><em>,</em>

The youngest brother is <em><u>James</u></em> and his age is <em><u>18 Years</u></em>.
