Answer:

which type of equation just tell we are here to help if we can

Answer:  Take the information given in the situation. Consider the relationships between the amounts, numbers and unknowns that are in the description.

If the word "is" or "are" is included in the description, that is equivalent to an equal sign.

Words like "and," "also" "more than" and "combined" are clues that there may be addition. "Total" often means the sum of an addition equation.  

"From" and "difference" are clues that there is subtraction.

"Times" "by" and "of" art clues for multiplication. "Find the Area of. . ." dedinitely requires multiplication.

"Ratio," 'into' "per" and "among" are clues to division.

Use a letter x, y, d, t, or whatever helps identify the

Step-by-step explanation: Without a specific situation, it is impossible to give a specific answer.

Examples:  The total number of seats in the auditorium is 125. 75 tickets have been sold already. How many more tickets are left. (This is the unknown)

The Total is  the given 75 plus the unknown.

125 = 75 + x   is the equation to start with

What is three-fourths of twelve?  "What" is the unknown.

x = 3/4 × 12  is the  equation to start with.

The ratio of red marbles to blue marbles is 2:3  There are 25 marbles all together. How many red marbles and how many blue marbles.

In this question there are two equations

2r + 3b = 25 This is the equation for the total    r = 2b/3 is the division

Substitute the value of "r" from the second equation to solve the first equation

2(2b/3) + 3b = 25

Answer:

$14.07

Step-by-step explanation:

100-15=85

You change this into a multiplier 0.85.

18x0.85=15.30

100-8=0.92

0.92x15.30=14.07

Step-by-step explanation:

Answer:

The probability the earth is saved is [tex]P(X >  3) = 0.8753 [/tex]

Step-by-step explanation:

From the question we are told that  

   The number of missiles lunched by earth is n =  500

   The probability that each missile will hit the rocket is  p(x) =  0.01

Generally the expected number of  missiles that will hit the rocket is  

    [tex] \lambda =  n  *  p(x)[/tex]

    [tex]\lambda =  500  *  0.01 [/tex]

    [tex]\lambda =  5[/tex]

Gnerally the probability that Earth will be saved is mathematically represented as

      [tex]P(X >  3) =  1 - P(X \le 2)[/tex]

=>    [tex]P(X >  3) =  1 -  P( X = 0 ) + P(X =1 ) + P( X = 2) [/tex]

Gnerally the probability distribution function of a Poisson distribution is

      [tex]P(K) =  \frac{e^{- \lambda t } *  (\lambda *  t)^k}{k!}[/tex]

Here t =  1

Hence

      [tex]P( X = 0 ) =  \frac{e^{-5} *  5^0 }{0!}[/tex]

      [tex]P(X =1 ) =\frac{e^{-5} *  5^1 }{1!}[/tex]

     [tex]P( X = 2) = \frac{e^{-5} *  5^2 }{2!}[/tex]

 [tex]P(X >  3) =  1 - [ \frac{e^{-5} *  5^0 }{0!} + \frac{e^{-5} *  5^1 }{1!} +  \frac{e^{-5} *  5^2 }{2!}][/tex]

[tex]P(X >  3)= 1 - [ \frac{0.00673 }{1} + \frac{0.033689}{1} +  \frac{0.168449 }{2}][/tex]

[tex]P(X >  3) = 0.8753 [/tex]

Answer:

The slope of the line is 8.

Step-by-step explanation:

To solve this problem, we can use the formula for slope:

slope = m = (y2 - y1)/(x2 - x1)

If we substitute in two points from the table into this formula, we get:

slope = m = (11-3)/(1-0) = 8/1 = 8

Therefore, the slope of the line is 8.

We can also see this by looking at the table itself.  Since both x and y are increasing together, we know that the slope should be positive.  For every increase in 1 in x, y increases by 8; this confirms that the slope of the line is 8.

Hope this helps!

Answer:

18 Nickels, 6 Quarters

Step-by-step explanation:

For this problem, let's build a system of equations to find the number of nickels and dimes you have.  Let N represent the number of nickels and Q represent the number of quarters you have.

The first equation, you have 3 times as many nickels as quarters:

N = 3Q

The second equation, you have a total of $2.40.  Given we know nickels are $0.05 and quarters are $0.25:

0.05N + 0.25Q = 2.40

Now, let's use the two equations to find the number nickels and quarters you have.

N = 3Q

0.05N + 0.25Q = 2.40

0.05(3Q) + 0.25Q = 2.40

0.15Q + 0.25Q = 2.40

0.4Q = 2.40

Q = 6

Now, let's plug the value back into the equation:

N = 3Q

N = 3(6)

N = 18

And we can verify these values with the second equation:

0.05N + 0.25Q = 2.40

0.05(18) + 0.25(6) ?= 2.40

0.90 + 1.50 ?= 2.40

2.40 == 2.40

Therefore, we have found and verified the amount of Nickels and Quarters you have.

Cheers.

Answer:

B. 61

Step-by-step explanation:

Given that ∆PQR and PQS are congruent, it follows that their corresponding sides are of the same length.

Therefore,

[tex] RQ = SQ [/tex]

[tex] 3x + 16 = 7x - 24 [/tex]

Collect like terms

[tex] 16 + 24 = 7x - 3x [/tex]

[tex] 40 = 4x [/tex]

Divide both sides by 4

[tex] \frac{40}{4} = \frac{4x}{4} [/tex]

[tex] 10 = x [/tex]

[tex] x = 10 [/tex]

Find PQ:

[tex] PQ = 2x + 41 [/tex]

substitute x = 10 into the equation

[tex] PQ = 2(10) + 41 [/tex]

[tex] PQ = 20 + 41 [/tex]

[tex] PQ = 61 [/tex]

your answer is x< -2.... because 1st we have to take common between 5x and 10.

Answer:

[tex]\frac{-10}{3}[/tex]

Step-by-step explanation:

Cancel x+2 by multilying it with all terms.

x=2+4(x+2)

SImplify both sides

x=4x+10

Subtract 4 on both sides

−3x=10

Divide bot sides by -3

You get [tex]\frac{-10}{3}[/tex]

Answer:

Hi there!

Your answer is:

The length is 17

Step-by-step explanation:

L= 11+w

P=46

perimeter formula:

W+W+L+L = P

W+W+(11+w)+(11+w) = P

First solve for W

4W+22 = 46

-22

4w=24

/4

w=6

Now plug in W for the L formula

l=11+w

L= 11+ 6

L=17

Step-by-step explanation:

The question says "20% of 45 ".

So, framing it , we get:-

[tex]\tt{\dfrac{20}{100}\times 45}[/tex]

So, solving it,

[tex]\tt{\dfrac{20\times 45}{100}}[/tex]

[tex]\tt{\dfrac{900}{100}}[/tex]

[tex]\tt{9}[/tex] is the answer.
