Answer:

Fraction: 1/ 5 n= 7

Step-by-step explanation:

To find n first you cross multiply : 2/ 10 * n / 35

= So we multiply 10 and n ( answer = 10n)

= Then 2 and 35 ( multiply) ( answer = 70)

Now algebra

70 = 10n

Divide both sides by 10

10n / 10 = 70 / 10

n = 7

The fraction becomes 7 / 35

When this is simplified the answer is 1 / 5

To simplify you divide the numerator and denominator of the fraction by 25 ( GCF )

Perform the operation indicated, then place the answer in the proper location on the grid. Write your answer in descending power

VikaD [51]

Answer:

<h3>The answer after performing the indicated operation is in descending powers of x is $5x^2-7x+15$ </h3>

Step-by-step explanation:

Given expression is $(6x^2-4x+11)+(4-x^2-3x)$

<h3>To perform the operation indicated, then place the answer in the proper location on the grid and also Write answer in descending powers of x:</h3>

Now solve the given expression as below ( that is perform the operation indicated)

$(6x^2-4x+11)+(4-x^2-3x)$

$=6x^2-4x+11+4-x^2-3x$

Adding the like terms we get

$=5x^2-7x+15$

$(6x^2-4x+11)+(4-x^2-3x)=5x^2-7x+15$

<h3>The answer after performing the indicated operation is in descending powers of x is $5x^2-7x+15$ </h3>

Rudiy27

Answer: r=-7/6y+7/2

Step-by-step explanation:

Step 1: Add -5 to both sides.

6r+5+−5=−7y+26+−5

6r=−7y+21

Step 2: Divide both sides by 6.

6r/6=-7y+21/6
