Answer:

Step-by-step explanation:

- 2.5(4w - 4) = -6

-2.5×4w+2.5×4=-6

-10w+10=-6

-10w=-6-10

-10w=-16

Cancel the -sign from both side soqe get

10w=16

W=16/10

W=1.6

So the value of w is 1.6

Answer:

5(9x-5)

Step-by-step explanation:

Answer:

Step-by-step explanation:

I'm not entirely sure what the question is, but I suspect the answer is not prime.

9x^2 - 4

factors into two factors  (3x + 2)(3x - 2)

Suppose x = 11 which is prime.

9*121 - 4

1085 which ends in a 5 so the expression is not prime.

In fact, the two factors are 3*11 + 2 = 35  and 3*11 - 2 = 31

31*35 = 1085

Answer:

  F.  (3x +2)(3x -2)

Step-by-step explanation:

The given expression is the difference of two squares, so can be factored accordingly.

  9x^2 -4 = (3x)^2 -2^2 = (3x +2)(3x -2) . . . . . matches F

Answer:

996

Step-by-step explanation:

the three digit number is;

996

Step-by-step explanation:

The three digit can be written xyz

ones digit is equal to 1/3 the sum of the two other digits

z = 1/3(x + y)

x + y + z = 24

Tens digit is same as hundreds digit

That means x = y

z = 1/3 (x + x) = 2x/3

So;

2x/3 + x + x = 24

Multiply through by 3

2x + 3(2x) = 72

8x = 72

x = 72/8

x = 9

x = y = 9

z = 1/3(18)

z = 6

Ordered pairs

Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice

Answer:

Step-by-step explanation:

Here is the complete question;

M is the midpoint of line segment LN. If LM= 3x + 5 and LN= 5x + 40, find the length of LN.

Since M is the midpoint of LN, hence LM + MN = LN and LM = MN

LM + LM = LN

2LM = LN ..... *

Given;

LM= 3x + 5

LN= 5x + 40

Substitute into the eqn *

2(3x+5) = 5x+40

6x+10 = 5x+40

6x-5x = 40-10

x = 30

Get the length LN

LN= 5x + 40

LN = 5(30)+40

LN = 150+40

LN = 190

Hence the length of LN is 190

Answer:

190

Answer:

The volume of soap that Ryan measured is 354.9 mL. Therefore, option C is the correct answer.

Given that, for the volume of soap in a bottle, Ryan determined the margin of error as 354.85 mL to 354.95 mL.

We need to find the volume of soap that he measured.

A margin of error tells you how many percentages points your results will differ from the real population value.

Now, the margin of error is 354.85 - 354.95

The volume=354.9 mL (Mid value of 354.85 - 354.95 )

The volume of soap that Ryan measured is 354.9 mL. Therefore, option C is the correct answer.

Answer:

A: 35

Step-by-step explanation:

DG is the combined segments DO and OG. In other words:

[tex]DG=DO+OG[/tex]

We know that DG is 60. DO is (4x-3) and OG is (2x+21). So, substitute:

[tex]60=(4x-3)+(2x+21)[/tex]

Solve for x. Combine like terms:

[tex]60=6x+18[/tex]

Subtract 18 from both sides:

[tex]42=6x[/tex]

Divide both sides by 6. Hence, the value of x is:

[tex]x=7[/tex]

GO is defined as (2x+21).

So, to find GO, we can now substitute 7 for x and evaluate. Therefore:

[tex]GO=2(7)+21=14+21=35[/tex]

Hence, our answer is A.

Answer:

The total no. of purple marbles will be:

[tex] \boxed{ \underline{ \rm{28}}}[/tex]

Step-by-step explanation:

It is given that for every 5 blue marbles, we have 4 purple marbles. And similarly we have to find for the no. of purple marbles for 35 blue marbles.

First, Let's divide these 35 blue marbles in groups of 5. We will get:

➝ 35 ÷ 5 = 7 groups

For each group of 5 marbles, there are 4 purple marbles. So for 7 groups, No. of purple marbles will be:

➝ 4 × 7 = 28 purple marbles.

And we are done! :D

Advice for the future, use math w a y next time for stuff like this.

Answer:

-$13.5

Step-by-step explanation:

Let x be a random variable of a count of player gain.

- We are told that if the die shows 3, the player wins $45.

- there is a charge of $9 to play the game

If he wins, he gains; 45 - 9 = $36

If he looses, he has a net gain which is a loss = -$9

Thus, the x-values are; (36, -9)

Probability of getting a 3 which is a win is P(X) = 1/6 since there are 6 numbers on the dice and probability of getting any other number is P(X) = 5/6

Thus;

E(X) = Σ(x•P(X)) = (1/6)(36) + (5/6)(-9)

E(X) = (1/6)(36 - (5 × 9))

E(X) = (1/6)(36 - 45)

E(X) = -9/6 = -3/2

E(X) = -3/2

This represents -3/2 of $9 = -(3/2) × 9 = - 27/2 = -$13.5
