Paul [167]

Given:

Jerome ate 1/2 of the sandwich , Kevin ate 1/3 of the sandwich, and Seth ate the rest.

To find:

The ratio of jerome's share to kevin's share to seth's share.

Solution:

Jerome ate 1/2 of the sandwich. So,

Jerome's share = $\dfrac{1}{2}$

Kevin ate 1/3 of the sandwich. So,

Kevin's share = $\dfrac{1}{3}$

Seth ate the rest. So,

Seth's share = $1-\dfrac{1}{2}-\dfrac{1}{3}$

= $\dfrac{6-3-2}{6}$

= $\dfrac{1}{6}$

The ratio of jerome's share to kevin's share to seth's share is:

$\dfrac{1}{2}:\dfrac{1}{3}:\dfrac{1}{6}$

To simplify the ratio multiply the ratio by 6.

$\dfrac{1}{2}\times 6:\dfrac{1}{3}\times 6:\dfrac{1}{6}\times 6$

$3:2:1$

Therefore, the ratio of jerome's share to kevin's share to seth's share is 3:2:1.

3x^2 – 8x + 5 = 5x^2

Ghella [55]

Answer:

Step-by-step explanation:

$3x^2 -8x +5 = 5x^2\\\\5x^2 - 3x^2 + 8x -5 =0\\\\2x^2 +8x -5 = 0\\\\$

a = 2, b = 8, c = -5

$x = \frac{-b \pm \sqrt{b^2 -4ac} }{2a}\\\\x = \frac{-8 \pm \sqrt{8^2 - ( 4 \times 2 \times (-5))} }{2 \times 2}\\\\x = \frac{-8 \pm \sqrt{64 +40} }{4}\\\\x = \frac{-8 + \sqrt{64 +40} }{4} \ , \ x = \frac{-8 - \sqrt{64 +40} }{4}\\\\x = \frac{-8 + \sqrt{104} }{4} \ , \ x = \frac{-8 - \sqrt{104} }{4}\\\\x = \frac{-8 + \sqrt{4 \times 26} }{4} \ , \ x = \frac{-8 - \sqrt{4 \times 26} }{4}\\\\x = \frac{-8 +2 \sqrt{26} }{4} \ , \ x = \frac{-8 - 2\sqrt{26} }{4}\\\\$

$x = \frac{-4 + \sqrt{26} }{2} \ , \ x = \frac{-4 - \sqrt{26} }{2}$

Use the number line to answer the following

adelina 88 [10]

There are 4/7 groups of 7/4 in 1 and 3 divided by 7/4 is 12/7

<h3>How to evaluate the expressions</h3>

<u>1. How many groups of 7/4 are in 1</u>

Here, we have:

Groups = 7/4

Entity = 1

The number of groups is calculated as:

Number =Entity/Groups

So, we have

Number = 1/(7/4)

Evaluate

Number = 4/7

Hence, there are 4/7 groups of 7/4 in 1

<u>2. 3 divided by 7/4</u>

Here, we have:

Divisor = 7/4

Dividend = 3

The quotient is calculated as:

Quotient = Dividend/Divisor

So, we have:

Quotient =3/(7/4)

Evaluate

Quotient = 12/7

Hence, 3 divided by 7/4 is 12/7
