Citrus2011 [14]4 years ago
4 0

Answer:

- 5x² + 3x + 27

Step-by-step explanation:

To find the polynomial subtract 5x² - 3x - 9 from 18, that is

18 - (5x² - 3x - 9) ← distribute parenthesis by - 1

= 18 - 5x² + 3x + 9

= - 5x² + 3x + 27 ← required polynomial

Choose the symbol that correctly compares these mixed numbers.
Anastasy [175]

Answer:

It is 7 2/11 is less then 7 4/10

Step-by-step explanation:

You do not have to worry about the whole number because they are the same. You have to compare the fractions, so if comparing fractions 10 is less then 11 so 1/10 has a larger space then 1/11. That is how i got the answer. Hope this helps. Am I right?

Question 5 <br> show the work please
Pani-rosa [81]

Answer:

D) 27

Step-by-step explanation:

It's a rectangle so the opposite sides are congruent to each other.

<em />

<em>Long Side:</em>

6x + 6 = 42

subtract 6 from both sides:

6x = 36

divide both sides by 6:

x = 6

<em />

<em>Short Side:</em>

5y + 5 = 30

subtract 5 from both sides:

5y = 25

divide both sides by 5:

y = 5

<em />

<em>The Equation:</em>

2x + 3y

substitute in the values:

2(6) + 3(5)

do the multiplication:

12 + 15

add the values together:

27

Jose has $20 more than Sarah. Their combined mobey totals $90. Write and solve an algebric model to determine the amount of mone
scoray [572]

Let S= the amount of money Sarah has.

Let J= the amount of money Jose has

J= S+20

J+S=90

But we also know that J can equal S+20

So,

S+20+S=90

2S+20=90

2S=70

S=35

So Sarah has $35, and Jose has $35+$20, so he has 55$

A sum of money is divided among Khairul, Michael and Ethan in the ratio
Leto [7]

Answer:

$360

Step-by-step explanation:

The intial ratio of the sum shared between Khairul, Michael and Ethan is 6 : 4 : 5.

This would be 6x : 4x : 5x

Khairul gives $30 to Michael and $15.

The ratio is. Now;

(6x - 45) : (4x + 30) : (5x + 15)

We are told this is equal to the ratio 7:6:7

Thus;

((6x - 45) + (4x + 30))/(5x + 15) = (7 + 6)/7

(10x - 15)/(5x + 15) = 13/7

Factorize the left hand side;

5(2x - 3)/5(x + 3) = 13/7

5 will cancel out to get;

(2x - 3)/(x + 3) = 13/7

Cross multiply to get;

7(2x - 3) = 13(x + 3)

14x - 21 = 13x + 39

14x - 13x = 39 + 21

x = 60

Amount Khairul had initially was denoted as 6x.

Thus,6x = 5 × 60 = $360
