yo i could use some help please, thank you

Answer:

Step-by-step explanation:

We calculate terms in parentheses: +(3x-84-()), so:

3x-84-()

We add all the numbers together, and all the variables

3x

Back to the equation:

+(3x)

x=0/3

x=0

Answer: b

Step-by-step explanation:  y=3x−84.

y=3x−84

Answer:

Step-by-step explanation:

This is one of those things that will drive you insane until you understand the answer.

Every y value is 4 no matter what x is.

The perpendicular will meet y = 4 at the point (6,4)

Answer: So the equation has to be x = 6.

The blue line is y = 4

The red line is x = 6

The point of intersection is marked.

Step-by-step explanation:

97+47+77 = 221

Answer:

The number is 218.

2=2×1

8=2×4

Answer:

Range = 5

Mode = 7

Step-by-step explanation:

To find range we first need to find the highest number and the lowest number

3 , 4 , 4 , 7 , 7 ,7 ,7 7, 8

least number = 3

highest number = 8

now substract the lowest number from the highest to get the range

= 8-3

= 5

range = 5

Mode : the most common number in the list will be our mode

7 is our mode as it came 5 time in the list

Answer:

4, 5, 6

Step-by-step explanation:

The only three consecutive positive integers that fits the criteria is 4, 5, and 6 since the product of the two larger integers, 5 and 6, is 30 and 4, 5, 6 is consecutive.

Answer:

4 5 and 6

2 – X – 3= 0

X = 2 - 3

X = -1

Answer:

Option A.

Step-by-step explanation:

A rational number is a number that can be expressed in a fraction (ratio of integers).

Option A is rational since both quantity are rational

Option B is irrational since

[tex]\sqrt{3}\cdot\sqrt{9}=\sqrt{27}[/tex]

where 27 is not a square of any fractions/ integers. Hence, it cannot be expressed as a fraction and is irrational.

Option C is irrational. Note that PI is irrational. Any rational multiples of an irrational number must also be irrational.

Option D is irrational. Similar to Option B.

Answer:

A)x +12 = y

B) (X +y) = 4x

A) x -y = -12

B) -3x + y = 0

Adding both equations:

-2x  = -12

x = 6

y = 18

Answer:

They are actually 53.9 miles away.

Step-by-step explanation:

1 in = 15.4 mi

Set up an equation:

Variable x = number of miles

1/15.4 = 3.5/x

Cross multiply:

1 × x = 15.4 × 3.5

x = 53.9

Answer:

76

Step-by-step explanation:

Firstly I called the original number 'y'

Then i formulated an equation by adding in the processes mentioned in the question: (y + 14) x 2/3 = 60

Then i solved the equation

First I multiplied (y + 14) by 2/3: (y + 14) x 2/3 = (2/3 x y) + (14 x 2/3) = 2y/3 + 28/3

I simplified that to 2y + 28/3 = 60 since you can add fractions which have the same denominator

Then to get rid of the fraction i multiplied both sides by 3 to get 2y + 28 = 180

Then i took away 28 from both sides to get 2y = 152

Then i divided both sides by 2 to get 'y'(the original number) on its on: y = 76

Answer:

= 3.65.

Step-by-step explanation:

You know that Tom has 23 coins in total. That means the number of dimes and the number of quarters equals 23.

D + Q = 23

You also know that the total value of the coins is $3.65. A dime is worth $0.10 and a quarter is worth $0.25, so:

0.10*D + 0.25*Q = 3.65

That says that 10 cents per dime times the number of dimes, plus 25 cents per quarter times the number of quarters is three dollars and sixty-five cents.

So you have a system of linear equations:

D + Q = 23

0.10D + 0.25Q = 3.65

I'm going to multiply the bottom row by 100 to clear the decimals.

D + Q = 23

10D + 25Q = 365

Now I can multiply the top row by -10 to eliminate the D terms

-10D - 10Q = -230

10D + 25Q = 365

________________

0D + 15Q = 135

15Q = 135

Q = 9

Tom has 9 quarters.

If D + Q = 23, and Q = 9, then:

D + 9 = 23

D = 14

Tom has 14 dimes.

Always good to double check:

9 quarters is worth $2.25. 14 dimes is worth $1.40. These should sum to $3.65.

2.25 + 1.40

Answer:

Answer: Radius is 3 ft

Step-by-step explanation:

Formular:

[tex]{ \boxed{V = \frac{4}{3} \pi {r}^{3} }} \\ [/tex]

substitute:

[tex]36\pi = \frac{4}{3} \pi {r}^{3} [/tex]

multiply all sides by 3:

[tex](36\pi \times 3) = ( \frac{4}{3} \pi {r}^{3} ) \times 3 \\ \\ 108\pi = 4\pi {r}^{3} [/tex]

divide all sides by π :

[tex] \frac{108\pi}{\pi} = \frac{4\pi {r}^{3} }{\pi} \\ \\ 108 = 4 {r}^{3} [/tex]

divide all sides by 4:

[tex] \frac{108}{4} = \frac{4 {r}^{3} }{4} \\ \\ {r}^{3} = 27[/tex]

take a cube root:

[tex] \sqrt[3]{ {r}^{3} } = \sqrt[3]{27} \\ r = \sqrt[3]{(3 \times 3 \times 3)} \\ r = \sqrt[3]{ {3}^{3} } \\ \\ r = 3[/tex]

the correct answer is false

give brainliest please I need it to level up

Step-by-step explanation:

the gcf of 13 and 65 is 13

13 + 65 can be rewritten using the gcf as

13( 1 + 5)

The greatest common factor of 13 and 65 is 13.

The 13 + 65 could be written using the gcf as 13(1 + 5).

Given that,

Based on the above information, the calculation is as follows:

The GCF is 13

And, it could be rewritten as 13(1 + 5).

Answer:

[tex]a_n=9n+5[/tex]

Explanation:

[tex]a_n=9n+5[/tex] will find any term in the sequence, just replace "n" with the term you want.

Example:

If you wanted to find the 9th term, replace [tex]a_n[/tex] with [tex]a_9[/tex], and you'll get

[tex]a_9=86[/tex]

86 is the 9nth term.

Answer:

p = -1.66

Step-by-step explanation:

-3p = p - 1 - (p - 6)

-3p = p - 1 - p + 6

-3p = 5

p = 5/-3

p = -1.66

Answer:

No; Because 9 is a factor of 4554. By divisibility rules sum of digits of 4554 is 18, which is a number divisible by 9. Hence 4554 is divisible by 9.

Step-by-step explanation:

#1

Length = Area/Width

Length = 5673/61

Length = 91 m

#2

Perimeter = 2(l + w)

292 = 2(88 + w)

292/2 = 88 + w

146 = 88 + w

146 - 88 = w

58 = w

Answer:

for 7, the answer is angle BFC, They share a side and a vertex.

Step-by-step explanation:

Answer:

n = 7

Step-by-step explanation:

3 = 10 - n

-10   -10              subtract 10 from both sides

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

-7 = -n                -n is the same as -1n so let's divide both sides by -1

/-1    /-1

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

7 = n
