Answer:

A-(4÷-0.4)+(0.8)

b-(4÷-0.4)+(0.8÷-0.4)

Answer:

Answer is 1/3

Step-by-step explanation:

If you divide the numerator and denominator by five you get 3/9

3/9 can be reduced if you divide the numerator and denominator by 3, then your answer is 1/3 (since 3 goes into 3 once, and 3 goes into 9 three times.)

Answer:

-20, -12, -8, -1, 1, 5, 10

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) If you really meant X^2+12=40, then this simplifies to x^2 = 28, and therefore x = ±√28, or x = ±2√7.

2) If you meant X^2+12x=40:

a) Take half of the coefficient of x:  that would be (1/2)(12), or 6.  

b) Square this result, obtaining:  6² = 36

c) Add this 36 to x^2 + 12x + 40, and then subtract it:  We get:  

x² + 12x + 36 - 36 = 40, or x² + 12x + 36 = 76

We have to add 36, as indicated above, to "complete the square."

Answer:

a) The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8x = 32

b) Nina delivered 4 times as many papers the second week as the first week

Step-by-step explanation:

From the question, we are told that:

Nina delivers newspapers.

In the first week, she delivers 8 papers.

In the second week, she delivers 32 papers.

Let x represent the number of times

The equation can Nina use to find how many times as many papers she delivered the second week as the first week is given as:

8paper × x = 32 papers

8x = 32

Solving for x

8x = 32

x = 32/8

x = 4 times

Therefore, Nina delivered 4 times as many papers the second week as the first week

Answer: -8,-4,0,4,8,12

Step-by-step explanation:

The six numbers of the arithmetic progression are -8, -4, 0, 4, 8, 12

where

a = first term

d = common difference

n = number of terms

d = 4

first term = a

2nd term = a + 4

3rd term = a + (3 - 1) 4 = a + 8

4th term = a + (4 - 1) 4 = a + 12

5th term = a + (5 - 1) 4 = a + 16

6th term = a + (6 - 1) 4 = a + 20

sum of its 6 terms = 12

Therefore,

a + a + 4 + a + 8 + a + 12 + a + 16 + a + 20 = 12

6a + 60 = 12

6a = 12 - 60

6a = -48

a = -48/6

a = -8

2nd term = -8 + 4 = -4

3rd term = -8 + 8 = 0

4th term = -8 + 12 = 4

5th term = -8 + 16 = 8

6th term = -8 + 20 = 12

Answer:

$9.60

Step-by-step explanation:

8*1.2

Answer:

see explanation

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

A

There is a common difference d between consecutive terms , that is

d = 5 - 2 = 8 - 5 = 11 - 8 = 14 - 11 = 3

Thus the sequence is arithmetic with a₁ = 2 and d = 3, then

[tex]a_{n}[/tex] = 2 + 3(n - 1) = 2 + 3n - 3 = 3n - 1

[tex]a_{n}[/tex] = 3n - 1

B

There is a common difference d between consecutive terms , that is

d = 11 - 9 = 13 - 11 = 15 - 13 = 17 - 15 = 2

Thus the sequence is arithmetic with a₁ = 9 and d = 2 , then

[tex]a_{n}[/tex] = 9 + 2(n - 1) = 9 + 2n - 2 = 2n + 7

[tex]a_{n}[/tex] = 2n + 7

Answer:

so for question a the ans is 3n-1

for question b the ans is 2n+7

Step-by-step explanation:

using the formula for arithmetic progressikn(a.p) a +(n-1)d, u use this formula because it has a common differnce

a=2, where a is first term or t1

d=t2-t1=5-2=3m where d is common difference

replace the values in the formula

2+(n-1)3

2+3n-3

3n-3+2

3n-1, this is the formula for the nth term

it will be 3n -1

if u try it

3(1)-1=2

3(2)-1=5

3(3)-1=8

3(4)-1=11

3(5)-1=14

using the formula for a.p, a+(n-1)d

a=9, because it is the first term

d=t2-t1=11-9=2

replace the values in the formula

9+(n-1)2

9+2n-2

2n+9-2

2n +7,this is the formula for the7th term

if u try it

2(1)+7=9

2(2)+7=11

2(3)+7=13

2(4)+7=15

2(5)+7=17

Answer:

X = 9.2

Step-by-step explanation:

You have to use the pythagorean theorm, which is a squared + b squared  = c squared. Looking at the triangle, the vertical line is 6, and the horizontal is 7.

6squared + 7squared = c squared

85 = csquared

Take the square root of both sides to get rid of the squared on the c.

sqroot of 85 = 9.2

Answer:

16

Step-by-step explanation:

If x = 3 and  , y = 2.  

2 x 3 = 6  and 5 x 2 = 10.

10 + 6 = 16

The value of the expression 2x + 5y when x = 3 and y = 2 is 16.

We have to determine, the value of the expression 2x + 5y when x = 3 and y = 2.

According to the question,

Expression; 2x + 5y

To determine the value of the expression calculation must be done in a single unit following all the steps given below.

The value of expression 2x+5y,

When the value of x = 3 and y = 2,

Therefore,

[tex]= 2x + 5y[/tex]

Substitute the value of x = 3 and y = 2 in the given expression,

[tex]= 2(3)+ 5(2)\\\\= 6 + 10\\\\= 16[/tex]

Hence, The value of the expression 2x + 5y when x = 3 and y = 2 is 16.
