Need answer asap pls..............

Answer:

It's 4 I hope this helped.

If I subtracted 2 from 6 in Equation B. I would get 4. Putting 4 to replace the x in Equation A, it makes the equation make sense.

Step-by-step explanation:

3 ( 4 + 2 ) = 18

4 + 2 = 6

Answer:

[tex]\huge\boxed{\sf n = 5}[/tex]

Step-by-step explanation:

[tex]\sf \frac{4}{n} = \frac{4}{5} \\\\Cross \ Multiplying \\\\n * 4 = 4*5\\\\Divide \ both \ sides \ by \ 4 \\\\\frac{n*4}{4} = \frac{4*5}{4} \\\\n = 5 \\\\\rule[225]{225}{2}[/tex]

Hope this helped!

Answer:

n = 5

Step-by-step explanation:

[tex] \frac{4}{n} = \frac{4}{5} [/tex]

Dividing 4 on both the sides gives ,

[tex] = > \frac{4}{n} \div 4 = \frac{4}{5} \div 4[/tex]

[tex] = > \frac{4}{n} \times \frac{1}{4} = \frac{4}{5} \times \frac{1}{4} [/tex]

Cancelling 4 from numerator and denominator from both the sides ,

[tex] = > \frac{1}{n} = \frac{1}{5} [/tex]

Cross-multiplying the denominators of both sides,

[tex] = > n = 5[/tex]

Answer:

x= -4 & y=-12

Step-by-step explanation:

multiply y=3x by 2

giving you 2y=6x

subtracting 2y=x+20 from 2y =6x

=> 5x=-20

dividing through by 5

=> x=-4

put x=-4 into y=3x

=> y=3(-4)

y=-12

Answer:

3.2 cakes a hour

Step-by-step explanation:

Answer:

4 bags of purple beads and 3 bags of indigo beads.

Step-by-step explanation:

Total number of beads = 21 beads'

Total bags of beads = 4 bags

Purple beads = 3 purple beads

Indigo beads = 6

Let x be each bags of purple beads

Let y be each bags of indigo beads

Since there are 4 bags of bead then;

x + y = 4 ....1

If some of the bags contain 3 purple beads and the rest contain 6 indigo beads, then;

3x + 6y = 21

x + 2y = 7.....2

Subtract 1 from 2

y - 2y = 4 - 7

-y = -3

y = 3

Sunce x + y =7

x = 7-y

x = 7-3

x = 4

Hence there are 4 bags of purple beads and 3 bags of indigo beads.

Step-by-step explanation:

Answer:

B on edge

Step-by-step explanation:

Answer:

x= 3, y= -4

Step-by-step explanation:

Answer:

y=3x-1

Step-by-step explanation:

First, we must find the slope of the equation. To do that we take two ordered pairs from the graph.

(2,5) (10,29)

The equation for slope is m=y2-y1/x2-x1

m=29-5/10-2

m=24/8

m=3

Now, we will find the variable B.

5=3(2)+b

5=6+b

-1=b

That's how we get the equation!

y=3x-1

Answer:y= 3x-1

Step-by-step explanation:

m= y2-y1/ x2-x1=

29-5/10-2=3

Now,use: y-y1= m(x-x1)

y-5=3( x-2)

y= 3x-1

Answer:

the answer is 10 percent off because that is 13 dollars

Step-by-step explanation:

if you do 130 times 10 it is 1300, then divide by 100 it equals 13 dollars off. if you did the other coupon it would only be 10 dollars off

Answer:

98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day

 (0.3672 , 0.7328)

Step-by-step explanation:

Explanation:-

Given Random sample size n =40

Sample proportion

                            [tex]p = \frac{x}{n} = \frac{22}{40} = 0.55[/tex]

98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day

          [tex](p-Z_{\alpha } \sqrt{\frac{pq}{n} } , p + Z_{\alpha } \sqrt{\frac{pq}{n} } )[/tex]

The Z-value Z₀.₉₈ = Z₀.₀₂ = 2.326

98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day

    [tex](0.55-2.326\sqrt{\frac{0.55 X0.45}{40} } , 0.55 + 2.326\sqrt{\frac{0.55 X0.45}{40} } )[/tex]

  ( 0.55 - 0.1828 , 0.55 + 0.1828)

  (0.3672 , 0.7328)

Answer:

Step-by-step explanation:

98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day

The Z-value Z₀.₉₈ = Z₀.₀₂ = 2.326

98% confidence interval of the true proportion of all Americans who celebrate Valentine's Day

 ( 0.55 - 0.1828 , 0.55 + 0.1828)

Answer:

you just add X=8 to 5x-6

You always have to multiply it

so its 5•8-6= 34

Answer: The answer is 34

Step-by-step explanation: all you had to do was think all of the answers below are high numbers so you most likely had to multiply so i did 5x8-6=34

Answer:

[tex]a_{1}[/tex] = 12

[tex]a_{2}[/tex] = 20

[tex]a_{3}[/tex] = 28

Step-by-step explanation:

In order to find the values of the first three terms of this sequence we would have to substitute in the "n" values for the first three terms that we mention earlier so. So in order to find the value of the first term we will substitute n with 1 (since the first term will be written as [tex]a_{1}[/tex], and as you see 1 will be equal to n, use the same logic for the other three terms) , in order to find the value of the second term the n would be substituted with 2, and for the third value we will substitute n with 3.

[tex]a_{1}[/tex] = 8 x 1 + 4

[tex]a_{1}[/tex] = 8 + 4

[tex]a_{1}[/tex] = 12

Then.......

[tex]a_{2}[/tex] = 8 x 2 + 4

[tex]a_{2}[/tex] = 16 + 4

[tex]a_{3}[/tex] = 20

And finally .......

[tex]a_{3}[/tex] = 8 x 3 + 4

[tex]a_{3}[/tex] = 24 + 4

[tex]a_{3}[/tex] = 28

Answer:

170,070 residents

Step-by-step explanation:

Original population = 1500 residents

Total population after 6 years is calculated using the formula

A = P(1+r)^t

r is the rate = 120% = 1.2

t is the time = 6 years

P is the original population

A = 1500(1+1.2)^6

A = 1500(2.2)^6

A = 1500(113.379904)

A = 170,069.856

Hence the total people using the recycling program after 6 years is approximately 170,070 residents
