Given three consecutive odd integers, what is the greatest number if triple of the sum of thrice the third one and twice the first one is equal to 291? ( grid-in )

Answers

Let n be the smallest of these integers. The other two are then n + 2 and n + 4.

"triple of the sum of thrice the third one and twice the first one is equal to 291" is a long-winded way of saying

3 (3 (n + 4) + 2n) = 291

Solve for n :

3 (3n + 12 + 2n) + 291

3 (5n + 12) = 291

15n + 36 = 291

15n = 255

n = 17

Then the greatest of the three integers is n + 4 = 21.

The center of a hyperbola is located at the origin. one focus is located at (0, 20), and its associated directrix is represented by the line y = . what is the equation of the hyperbola? = 1 = 1 = 1 = 1

Answers

The equation of the hyperbola is D. [tex]y^2/16^2-x^2/12^2=1[/tex]

Calculations and Parameters:

Given that the focus is at (0, 20)

Directrix is y= -256/20

What is the relation between a, b, and c?

[tex]a^2 +b^2 = c^2\\b^2 + (16)^2= (20)^2\\b^2= 400 -256\\b^2= 144[/tex]

b= 12

Making use of the vertices, foci, asymptotes, directrices, and standard equation, we find the equation of the hyperbola is [tex]y^2/16^2-x^2/12^2=1[/tex]

Answers

Answer:

a=-3

b=6

Step-by-step explanation:

equation 1: ax+6

equation 2: -3x+b

get the -3 from equation 2 and plug it into equation 1

get the 6 from equation 1 and plug it into equation 2

What number is represented by P

Answers

The number that is represented by P is 0.0057

Narrow it down.The point P is between 5 * 10^-3 and and 6*10^-3When you go to the bottom line, P is on the 7th division from the left.Going from left to right increases PP is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.One of the answers is 5.7 * 10^-3The other answer is .0057I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.If it is not correct, then 5.7 * 10^-3 is the answer.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Before school began, Mrs. Weeks bought a total of 86 balls.

Total number of each type of ball 8.

footballs - There are 8 footballs.

Basketballs - Two more than twice the number of footballs are Basketballs .

So, Basketballs = 2 + 2(8)

= 18

Baseballs - Four less than 5 times the number of footballs are

Baseballs .

So, Baseballs = 5(8)- 4

= 36

Softballs - Six more than half of the baseballs are softballs.

So, Softballs = 6 + 1/2 baseballs are softballs

= 6 + 1/2 (18)

= 15

IDΚ, help, what's the value of x,
8x-2=-9+7x

Answers

Answer:

x = -7

Step-by-step explanation:

8x - 2 = -9 +7x

in this type of problem you have to get all the X's together on one side, and all the common variables together on the other.

8x = -7 + 7x (you add 2 to boths sides. The -2 and 2 clear out on the left side. The 2 and -9 added together forms -7 on the right)

x = -7 (you subtract 7x from both sides. The 7x and -7x cancel out on the right and you are left with on 1 x on the left side)

Answer:

x = -7

Step-by-step explanation:

In this question we have given an equation that is 8x - 2 = -9 + 7x . And we're aksed to find the value of x .

Solution : -

[tex] \longmapsto \qquad \: 8x - 2 = -9 + 7x[/tex]

Step 1 : Adding 2 to both sides :

[tex] \longmapsto \qquad \:8x - \cancel{ 2} + \cancel{ 2} = - 9 + 7x+2[/tex]

On further calculations, we get :

[tex] \longmapsto \qquad \:8x =7x - 7[/tex]

Step 2 : Subtracting 7x on both sides :

[tex] \longmapsto \qquad \:8x - 7x = \cancel{7x} - 7 - \cancel{7x}[/tex]

On further calculations, we get :

[tex] \longmapsto \qquad \: \red{\underline{\boxed{ \frak{x = - 7}}}}[/tex]

Henceforth , value of x is - 7 .

Verifying : -

Now ww are verifying our answer by substituting value of x in given equation . So ,

8x - 2 = -9 + 7x

8 ( -7 ) - 2 = -9 + 7 ( -7 )

-56 - 2 = -9 - 49

-58 = -58

L.H.S = R.H.S

Hence, Verified.

Therefore, our answer is correct .

If Sandra charges $4.00 for a cup of ice cream and $0.37 for each ice cream, What
function would represent the situation?
Remember it should look like y=mx+b.

Answers

Answer:y= 0.37x+4

Step-by-step explanation:
x is the amouny of ice cream, 0.37 is the amount charged per x plus the additional 4 for the cup

The slope of the linear equation is 0.37, then the linear equation will be represented as y = 0.37x + 4.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

If Sandra charges $4.00 for a cup of ice cream and $0.37 for each ice cream. Then the linear equation is given as

[tex]\rm y=mx+c[/tex]

We have

m = $0.37

c = $4

Then the linear equation will be

y = 0.37x + 4
