Step-by-step explanation:

(−9.206x)(14.04)  you just simplify

Answer:

(6, 1)

Step-by-step explanation:

x + 3y = 9

x + 4y = 10

---------------------

-1 (x + 3y = 9)

---------------------

-x - 3y = -9

x + 4y = 10

      1y = 1  or y =1

x + 4y = 10

x + 4(1) = 10

x + 4 = 10

   -4     -4

x = 6

I hope this helps!

Answer:

t=-1

Step-by-step explanation:

t - 2(3 - 2t) = 2t - 9

t - 6 + 4t = 2t - 9

5t - 6 = 2t - 9

5t - 2t = -9 + 6

3t = -3

t= -1

1x=7

7/1=7

Answer:

1234567890

Step-by-step explanation:

Each of the digits is divisible by their individual index in the number. Adding a 0 at the ends allows for the number to be divisible by 10 and completes the 10 digit requirement.

The first digit is divisible by 1

The second digit is divisible by 2

The third digit is divisible by 3

The fourth digit is divisible by 4

The fifth digit is divisible by 5

The sixth digit is divisible by 6

The seventh digit is divisible by 7

The eigth digit is divisible by 8

The ninth digit is divisible by 9

The full number is divisible by 10

Answer:

x ≤ 9

Step-by-step explanation:

Step 1: Write inequality

x - 9 ≤ 2(9 - x)

Step 2: Solve for x

Here we see that any solution less than or equal to 9 would work.

Answer:

x ≤ 9

Step-by-step explanation:

x -9 ≤ 2(9 -x)    

x -9 ≤ 18 -2x

+2x         +2x

3x -9 ≤ 18

    +9    +9

3x  ≤ 27

[tex]\frac{3x}{3}[/tex] ≤ [tex]\frac{27}{3}[/tex]

x  ≤ 9

Answer:

=> 0:2

divide the first number by the second number and multiply the result by 100 (if necessary)

> first term is 1

> second term is 2

solution :

1 ÷ 5 = 1/2 (2dp) which is =0,2

final solution:

=0:2

Answer:

Step-by-step explanation:

Answer:

you need to use the midpoint formula

Answer:

MN is [-3,2] sorry but not really sure about this because they are just two points and don't seem as segment.But when it asks for MN I don't know what to say else.

and midpoint of MN is -1/2

because

x=(x1+x2)/2=(-3+2)/2=-1/2

Step-by-step explanation:

1.5 mill + 40 cent per

sell for 75 per

change numbers

1, 500, 000 + 4 per

sell for 75 per

x = each sneaker

1, 500, 000 + 4 x

sell for 75 x

we want to sell 15, 000

put 15, 000 where x is

1, 500, 000 + 4 (15, 000)

sell for 75 (15, 000)

1, 500, 000 + 4 × 15, 000 = 1, 560, 000

sell for 75 × 15, 000 = 1125000

minus the amount to make sneakers from amount getting for the sneakers

loss = ?

Answer:

Step-by-step explanation:

I dont fully know if i am correct but i think its this:

p + r = 22

9p + 6r = 180

p = 22 - r

9(22 - r) + 6r = 180

198 - 9r + 6r = 180

-3r = -18

r = 6

p = 22 - 6

p = 16

[tex]\sqrt{x} sin(4)*x[/tex]

square root of sin(4) times x

The goal of this equation is to find an x value that will make both sides equal.

I probably shouldn't answer this question since I can't really find a solution to it, but I don't really think its solvable.

Answer:

There are 2.5 grams of niacin contained in the bottle.

First you have to find how many milligrams are in the bottle.

So you multiply 125 by 20 since there are 125 tablets and 20 milligrams in each one.

125*20=2500

So there are 2500 milligrams in the bottle. Then you have to convert it into grams. To do that you divide the mass by 1000.

2500/1000=2.5

So there are 2.5 grams in the bottle.

Step-by-step explanation: hope this helps :)

Answer:

2.5

Step-by-step explanation:

125 vitamins, each vitamin has 20 milligrams. convert 20 milligrams to grams. 0.02 grams of niacin in each vitamin. 125 multiplied by 0.02 is 2.5

Answer: a. 0.00032    B. 0.00672

Step-by-step explanation:

Given: Proportion of  island residents of a country have reduced their electricity usage (p) = 20%= 0.20

Here, residents have two choices either reduced electricity usage or not , hence it follows binomial distribution

Let X be a binomial variable that represents the number of successes .

Binomial distribution formula:

[tex]P(X)=^nC_xp^x(1-p)^{n-x}[/tex], n= sample size.

a.

[tex]P(X=5) = ^5C_5(0.20)^5(1-0.20)^{5-5}=(1)(0.20)^5(1)\\\\=0.00032[/tex]

b. [tex]P(X\geq4)=P(4)+P(5)[/tex]

[tex]^5C_4(0.20)^4(1-0.20)^{5-4}+0.00032\\\\=(5)(0.20)^4(0.80)+0.00032\\\\=0.0064+0.00032\\\\=0.00672[/tex]

There is some unnecessary information in the problem, first, it should be removed.

"The dosage of cough medicine for a child 4 to 6..."

"2 days"

Listing the age and days don't matter here, it's the rest of the problem that matters!

- - - - - - - - - - - - - - - -

"1/2(a teaspoon) every 4 hours,"  This is one dose. Multiply 1/2 by five to see how many teaspoons are consumed.

1/2 x 5 = 2 1/2 (teaspoons)
