Answers

Answer 1

Answer:

n = -11 / 9c = 49 / 48f = -2 / 9k = -13 / 9y = 23 / 24b = 19 / 10

Step-by-step explanation:

1. 5+9(1+4n)=-30

-5               -5

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

9 (1 + 4n) = -35

/9                /9

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

(1 + 4n) = -35/9

1 + 4n = -35/9

-1            -1

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

4n = -44/9

/4        /4

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

n = -11/9

2. 6(3-8c)=-31

   /6            /6

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

(3 - 8c) = -31/6

3 - 8c = -31/6

-3          -3

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

-8c = -49/6

/-8      /-8

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

c = 49/48

3. -21=8+9(f-3)

8 + 9 (f - 3) = -21           we switched sides here

-8                  -8

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

9 (f - 3) = - 29

/9              /9

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

f - 3 = -29/9

 +3        +3

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

f = -2/9

4. 9k-7-5=-25

9k - 12 = -25

    +12     +12

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

9k = -13

/9      /9

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

k = -13/9

5. 8(3y-6)=-25

   /8            /8

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

(3y-6) = -25/8

3y - 6 = -25/8

    +6        +6

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

3y = 23/8

/3      /3

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

y = 23/24

6. 16=-5(2b-7)

-5(2b-7) = 16            we switched sides here

/-5             /-5

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

(2b-7) = -16/5

2b - 7 = -16/5

     +7     +7

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

2b = 19/5

/2      /2

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

b = 19/10

Hanks pickup can travel 45 miles on 3 gallons of gas. How many gallons will Hanks pickup need to travel 30 miles?

Answers

2 gallons because 45/3=15 30/15=2

We have an algebra problem.

We will find that Hank's pickup needs 2 gallons of gas to travel 30 miles.

The information given is:

The pickup can travel 45 miles on 3 gallons of gas.

To find the number of miles that the pickup can travel per gallon of gas, we need to find the quotient between the amount that he travels (45 miles) and the amount of gas that he uses (3 gallons)

This is:

r = (45 miles)/(3 gallons) = 15 miles/gallon.

Now that we know this, the number of gallons needed to travel 30 miles is given by:

N = (30 miles)/(15 miles/gallon) = 2 gallons.

N = 2 gallons.

The pickup needs 2 gallons to travel 30 miles.

What is the midpoint of AB ?

Answer:

hope it helps you........

Step-by-step explanation:

The midpoint formula is

[tex] (\frac{x1 + x2}{2} ) \: and \: ( \frac{y1 + y2}{2} )[/tex]

Where (x1,y1) is one pair of the points and (x2,y2) is the other pair of points.

The points are

(-5,-4)

(-3,3) So the midpoint is

[tex]( \frac{( - 5 + ( - 3)}{2} )\: and \:( \frac{ - 4 + 3}{2} )[/tex]

Which gives us

What is the common difference of the following sequence? 27, 11, -5, -21, -37, . . .

Answers

Answer:

Find the common difference and the next term of the following sequence:

3, 11, 19, 27, 35...

Step 1. To find the common difference, subtract any consecutive pair of terms.

11 - 3 = 8

19 - 11 = 8

27 - 19 = 8

35 - 27 = 8

The difference is always 8, so d = 8.

Step 2. Use the common difference to find the next term.

Since the last term was 35, adding the common difference of 8 will find the next term. The next term is 35 + 8 or 43.

Step-by-step explanation:

mark me brainliest plz

Answer:
