Answer:

B = 61°

C = 61°

Step-by-step explanation:

The sum of all the angles is 360.

When the angles are formed with straight lines like shown the angles back to back are equivalent or equal.

So you can take 119 and add it by itself to get 238.

You then get 360 and subtract 238 which gets you 122.

Then divide 122 by two and you have the answer for both b and c which is 61.

Part B

J = 3x t

Answer Prt B: 3x

Answer Part A: ^          

                         |

The equation 3x =y models the relationship between jellyfish, and sea turtles such that the ratio of their numbers remain constant.

Ratio is the relationship between two numbers given by a quotient

If the ratio of two numbers x and y is x/y then the fraction x/y gives that what parts x is of y .

Given that there are 4 sea turtle and 12 jellyfish in the sea when Alex counted the number.

Ratio of number of sea turtle to number of jellyfish = 4/12 = 1/3

Let at any time the number of sea turtles be x and number of jellyfish be y

Then ratio of number of sea turtles to jellyfish = x / y

Given that this ratio remained constant during the remainder of his dive,

∴ x/y = 1/3

Cross multiply

⇒ 3x = y

The equation that models the relationship between jellyfish, and sea turtles is 3x =y

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.

Tip: The symmetric property of equality states that no matter what side the equations and answer are it will still be equal, but it only works for the equal sign.

The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.

A number system is defined as a system of writing to express numbers.

Given that 12 = 17 - 5, then 17 - 5 = 12

we need to check which property will be used.

The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.

The symmetric property of equality is really quite simple. This property states that if a = b, then b = a. That is, we can interchange the sides of an equation, and the equation is still a true statement.

Hence, the math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.

Answer:

1/2 is 0.5

but % means times by 0.01

so 1/2% is way more smaller

Answer:

x = 9.

Step-by-step explanation:

The first step I did was replace y with 6.

[tex]2x+3\cdot \:6=36[/tex]

I multiplied 3*6 next.

[tex]2x+18=36[/tex]

Then I subtracted 18 from both sides of the equation.

[tex]2x+18-18=36-18[/tex]

After, I simplified the equation.

2x=18

Divided the both by 2 and then simplified again to get...

[tex]\frac{2x}{2}=\frac{18}{2}[/tex]  

[tex]x=9[/tex]

So [tex]x=9[/tex].

Let's solve your equation step-by-step

7 7/8 +2 1/3 =x

Step 1: Simplify both sides of the equation

245/24 =x

Step 2:Flip the equation

x=245/24

Answer: x=10 5/24

Answer:

Approximately, each citizen will owe $81,626 just so that the government can pay all its debts in the coming 10 years

Step-by-step explanation:

What we have here is that the debt grows at a rate of 10% per decade

So in the next 10 years, the worth of the debt will be;

26.7 trillion + 7% of 26.7 trillion

= 26.7 trillion + 1.869 trillion

So the total debt will now be;

= 28.569 trillion

So the amount each of the 350 million citizens owe the government will be;

28.569 trillion/ 350 million

= 81,625.71428571429

Approximately each citizen will owe $81,626

Answer:

vertex = (1, - 5 )

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

y = (x - 1)² - 5 ← is in vertex form

with (h, k ) = (1, - 5 ) ← vertex

Answer:

the amount that he would make in a week is $576.00

Step-by-step explanation:

14.40 * 40                                                                4*0=0

0*0=0                                                                       4*4=16

0*4=0                                                                        4*4+1=17

add the decimal                                                       4*1+1=5

0*4=0

0*1=0                                                                            Then you add and you

then you move on to the tens digit                            get a total of $576.00

Answer:

Step-by-step explanation:

I can give you the key points to look for without the graph. You'll have to do that.

New y intercept

The intercept increases by 2. Currently it is 2. The new y intercept is 2 + 2 = 4

The new Slope

The slope is multiplied by - 9. Currently it is (y2-y1)/(x2 - x1) = (2-0)/(0-6) = 2/-6= - 1/3

This is multiplied by - 9

-9*(-1/3) = 3

New equation

y = 3x + 4

x intercept.

The x intercept occurs when y = 0.

0 = 3x + 4

-4 = 3x

-4/3 = x
