9. What is the value to x in the inequality -4(6 + 5x) - 7 < - 9(2x+ 3)

9. What Is The Value To X In The Inequality -4(6 + 5x) - 7 &lt; - 9(2x+ 3)

Answers

Answer 1

Answer:

x [tex]\geq[/tex] -2

Step-by-step explanation:

Remove parentheses and distribute -4 and -9, calculate the difference,  move the variable and constant,  collect like terms. ( -2x [tex]\leq[/tex] 4), and divide both sides, and you'll end with -2.

Answer 2

Answer:

x > -2 (last choice)

Step-by-step explanation:

Using the distributive property multiple -4 to both integers

-24 - 20x - 7 < -18x - 27

-31 - 20x < -18x - 27

Add 27 on both sides

-4 - 20x < -18x

Add 20x on both sides

-4 < 2x

Divide each side by 2

x > -2

Answers

Answer:

16. Adults = $12

17. 750 ml

18. $9

19. 96 students

20. 5/6x

Step-by-step explanation:

16.

A child pays = $9

Bus fee = 1/3 of $9

= 1/3× 9

= $3

Admission fee for a child= amount paid - bus fee

= $9 - $3

= $6

What was the admission fee for adults, if children get in for haprice

Children = 1/2 of adults

$6 = 1/2 × adults

Adults = 6÷ 1/2

= $12

Adults = $12

17.

Leaking rate = 10 ml per minutes

One and quarter of an hour

1 hour = 60 minutes

Quarter of an hour = 15 minutes

Total time = 75 minutes

Air lost in 75 minutes = 10 ml × 75

= 750 ml

18. 4 glasses for $3

1 dozen of glasses = 12

12 glasses = $x

4 = 3

12 = x

Cross product

4*x = 3*12

4x = 36

x = 36 / 4

= 9

x = $9

19.

Total students = x

1/2x = soccer

Rugby = 1/2 of 1/2x

= 1/2 * 1/2x

= 1/4x

24 = 1/4x

x = 24÷1/4

= 24 × 4/1

x = 96 students

20.

Total petrol = x

Petrol in the tank = 1/2x

Petrol used = 1/3 of 1/2x

= 1/3 × 1/2x

= 1/6x

Petrol remaining after the trip = x - 1/6x

= 6x-x/6

= 5/6x

The price of a computer was decreased by 7% to £500. What was the price before the decrease? Give your answer to the nearest penny.

Answers

Answer:

£ 537.63

Step-by-step explanation:

original price = 100%

selling price = 100% - 7% = 93% = £500

just do the proportion or ratio

[tex] \frac{100\%}{93\%} = \frac{original \: price}{500} [/tex]

OP = 500 x 100% / 93%

OP = £ 537.634

rounded to the nearest penny and become £ 537.63

Q.10...In a cookie mix, we find chocolate chip cookies, spice cookies, and ginger cookies in a ratio of 4 : 3 : 3. If a bag of the mix contains 33 ginger cookies, how many chocolate chip cookies are there?

Answers

Answer:

13.2

Step-by-step explanation:

Let 4x represent the chocolate chip cookies

Let 3x represent the spice cookies

Let 3x represent ginger cookies

4x + 3x + 3x = 33

10x = 33

x = 33/10

x = 3.3

Since 4x represents chocolate chip cookies

4 × 3.3

= 13.2

Hence there are 13.2 chocolate chip cookies

Maximum value of z = 21

Minimum value of z = -9

Step-by-step explanation:

We have to maximize/minimize the given equation for the given constraints as,

x ≥ -1

y ≤ -2x + 3

y ≥ -1

By using the graphing tool,

Corner points for the feasible region are,

A(-1, 5), B(-1, -1) and C(2, -1)

For A(-1, 5),

z = 4x + 5y = 4(-1) + 5(5)

                  = -4 + 25

                  = 21

For B(-1, -1),

z = 4(-1) + 5(-1)

  = -4 - 5

  = -9

For C(2, -1),

z = 4(2) + 5(-1)

  = 8 - 5

  = 3

Maximum value of z = 21

Minimum value of z = -9

Given:

Gracie is sharing 75 marshminnows among 4 of her friends.

Each of her friends gets  the same number of marshminnows, and she gives them as many marshminnows as possible.

To find:

The remaining number of marshminnows she has.

Solution:

We have,

Total number of marshminnows = 75

Number of friends = 4

Divide 75 by 4.

[tex]4|\overline{75}|{18}\\ -4\\\text{\quad }\overline {35} \\ -32\\\text{\quad }\overline {\ 3\qaud }[/tex]

Here, quotient is 18 and remainder is 3. It means, each friend can be get maximum 18 marshminnows and the number of remaining marshminnows is 3.

Therefore, the correct option is B.
