-8-5n=64+3n

Answers

Answer 1

Answer:

n= -9

Step-by-step explanation:

The calculator is correct haha, You're welcome.

Answer 2
Answer:

n=-9

Explanation:
In order to solve for x, we must get x by itself on one side of the equation.
The equation is:
-8-5n=64+3n
5n is being subtracted and the inverse of subtraction is addition. Add 5n to both sides of the equation.
-8-5n+5n=64+3n+5n
-8=64+3n+5n
-8=64+8n
64 is being added and the inverse of addition is subtraction. Subtract 64 from both sides of the equation.
-8-64=64-64+8n
-8-64=8n
-72=8n
n is being multiplied by 8. The inverse of multiplication is division. Divide both sides of the equation by 8.
-72/8=8n/8
-72/8=n
-9=n

The solution to the equation is n=-9

-34x+6=-28
I need to learn how to solve for x

Answers

Answer:

x=1

Step-by-step explanation:

-34x+6=-28

       -6     -6

-34x=-34

-34     -34

x=1

Subtract 6 from both sides. on the left the 6 will be canceled out and on the right -28-6= -34

Than you divide -34 on both sides on the left the -34 will be canceled and on the right -34 divided bt-34 is positive 1. So x equals 1.

Answer:

Your answer is x = 11/17

Step-by-step explanation:

I gotchu!

Alright first, subtract 6 on both sides. After doing so, your equation should look like:

-34x = + 22

Then, divide -34 on both sides. Do not divide x though! The equation will look like:

x= -22/34

Now, let's simplify the answer. We can divide 22 and 34 by 2 so we will do that.

After simplifying, it should be 11/17.

Finally, keep it improper because you always should keep fractions improper when doing this.

Your answer is x = 11/17

Answers

Answer:

24 combinations

Step-by-step explanation:

For this problem, you use factorials. Factorials are when you multiply every number below it except zero. So like the factorial of 3 or 3! is 3*2*1 is 6.

Factorials are used to figure out how many combinations there are of something. So for you, we have 4 different quadrants so we write that as 4! (! is the sign for factorials.)

(62 points) Jim makes $5 an hour at the surf shop. His boss gives him a one time bonus of $50. Sarah makes $8 an hour at the clothes store. Her boss gives her a one time bonus of $14. After how many hours will their paychecks be the same?

Answers

Answer:

12 hours

Step-by-step explanation:

So we know that Jim makes $5 an hour and was given a one time bonus of $50. Using the information given, we can make the expression:

5h + 50

to represent how much Jim makes in h hours.

Now we also know that Sarah makes $8 an hour and was given a one time bonus of $14. Using this information, we can make the expression:

8h + 14

to represent how much Sarah makes in h hours.

Now to find how many hours it will take for their paychecks to be the same, we have to set the two expressions equal to each other and solve for h:

8h + 14 = 5h + 50

Now solve for h. Subtract 5h from both sides.

3h + 14 = 50

Subtract 14 from both sides.

3h = 36

Divide both sides by 3.

h = 12

So it will take 12 hours for their paychecks to be the same.

Answers

Answer:

The simplest radical form is [tex]9\sqrt{5}[/tex] ⇒ (c)

Step-by-step explanation:

To simplify any square root;

Factorize the number under the root using prime numbersTake out the root any number repeated twice as one number

Examples:

1. Simplify [tex]\sqrt{8}[/tex]

factorize 8 using prime numbers

8 = 2 × 2 × 2, then [tex]\sqrt{8}=\sqrt{(2)(2)(2)}[/tex]

Take two of 2 out the root, then [tex]\sqrt{8}=2\sqrt{2}[/tex]

2. Simplify [tex]\sqrt{18}[/tex]

factorize 18 using prime numbers

18 = 2 × 3 × 3, then [tex]\sqrt{18}=\sqrt{(2)(3)(3)}[/tex]

Take the two 3 out the root, then [tex]\sqrt{18}=3\sqrt{2}[/tex]

Let us simplify [tex]3\sqrt{45}[/tex]

∵ 45 = 3 × 3 × 5

∴ [tex]3\sqrt{45}=3\sqrt{(3)(3)(5)}[/tex]

→ Take the two 3 out by one 3

∴  [tex]3\sqrt{45}=3(3)\sqrt{5}[/tex]

→ Multiply the numbers out the root

∴ [tex]3\sqrt{45}=9\sqrt{5}[/tex]

The simplest radical form is [tex]9\sqrt{5}[/tex]

Which equation represents the lower unit rate of these two relationships?

A. y=2/9x

B. y=1/4x

C. y=1/5x

D. y=2/11

Answers

Answer:

the answer is d y=2

_ x

11

Step-by-step explanation:

I got it right on the test

2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11

A proportional relationship between variable y and x can be expressed as:

y = kx

Where,

k is the unit rate/constant of proportionality.

Therefore,

k = y/x

Thus, find the equation for the table and the graph respectively in order to determine which equation represents the lower unit rate.

Equation for the table using a pair of coordinates, say (11, 2):

Find, unit rate (k) by substituting x = 11, and y = 2 into k = y/x

Thus:

k = 2/11

Plug in the value of k = 2/11 into y = kx

The equation for the table is:

y = 2/11x

Equation for the graph using a point on the line, say (9, 2):

Find, unit rate (k) by substituting x = 9, and y = 2 into k = y/x

Thus:

k = 2/9

Plug in the value of k = 2/9 into y = kx

The equation for the table is:

y = 2/9x

In conclusion, 2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11

Heather purchased a prepaid phone card for $15 . Long distance calls cost 16 cents a minute using this card. Heather used her card only once to make a long distance call. If the remaining credit on her card is $12.76 , how many minutes did her call last?

Answers

Answer:

14 minutes

Step-by-step explanation:

In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left over after the call:

15 - 12.76 = 2.24

Then, we divide this number by 0.16:

2.24 / 0.16 = 14

So, Heather's call lasted 14 minutes

Sam counted his heartbeats while resting. His heart beat 220 times in 4 minutes. Sam's heart beat at the same rate for the 4 minutes.

Answers

The equation is , 220 x 4 = 880 , if his heart beat the same time every minute than multiple how many times it beat time the minute !

The equation for the number of beats per minute is 55 beats per minute

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of beats be = A

Now , the value of A = 220 beats

The total time required for Sam to have 220 beats = 4 minutes

So , the number of beats of Sam in 1 minutes is calculated by

The equation will be

The number of beats of Sam in 1 minutes is = total number of beats  / total time required for Sam to have 220 beats

The number of beats of Sam in 1 minute is = 220 / 4

The number of beats of Sam in 1 minute is = 55 beats per minute

Therefore , Sam would have 55 beats every minute or 55 beats per minute

And for the period of 4 minutes , Sam would have

Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4

Number of beats for 4 minutes = 55 x 4

Number of beats for 4 minutes = 220 beats in 4 minutes

Hence , The equation for the number of beats per minute is 55 beats per minute

2.4(x - 6) = -5.6x + 8​

Answers

Let's solve your equation step-by-step

2.4(x-6)=-5.6x+8

Step 1: simplify both sides of the equation

2.4(x-6)=-5.6x+8

(2.4)(x)+(2.4)(-6)=-5.6x+8 (distribute)

2.4x+-14.4=-5.6x+8

2.4x-14.4=5.6x+8

Step 2: Add 5.6x to both sides.

2.4x-14.4+5.6x=-5.6x+8+5.6x

8x-14.4=8

Step 3:Add 14.4 to both sides

8x-14.4+14.4=8+14.4

8x=22.4

Step 4 : Divide both sides by 8

8x/8 =22.4/8

A circular pool has an area of approximately 154 square feet. To the nearest foot, how much fencing is needed to completely surround the pool?

Answers

Given parameters:

Area of pool = 154ft²

Unknown:

The circumference or perimeter of the pool = ?

Solution:

The amount of fencing needed for the pool is the same as the circumference of the pool or the perimeter of the pool.

To solve this problem, we need to find the radius from the given area.

    Area of a circle  = π r²

        154  = π r²

           r² = [tex]\frac{154}{3.142}[/tex]   = 49

                    r  = 7ft

Now the circumference of a circle = 2 π r

                                                         =  2 x π x 7

                                                         = 44ft

The circumference of the circle is 44ft
