So my teacher gave me this super hard problem that i could't answer...its 999999999999x99999999999+9 billion can yall help me

Answer:

1st=3x+9, 2nd=8x, 3rd=4x+3y, 4th=neither, 5th=neither, 6th=4x+3y, 7th=3x+9, 8th=8x.

Step-by-step explanation:

for the 1st one cancel out the y's, 3x+9. for the 2nd one: 2x-1x+7x, (2-1+7)x, 8x. for the 3rd one: 2x+2y+2x+y, 4x+2y+y, 4x+3y. for the 4th one: 7x+x+0-y, 8x-y. for the 5th one: 2x+2y+2x, 4x+2y. for the 6th one: 4x+4y-y, 4x+3y. for the 7th one: 2x+6+x+3, 3x+6+3, 3x+9. for the 8th one: 5(2x)-2x, 5 * 2x-2x, 10x-2x, 8x.

Answer:

The answers would be :

first table (equivalent to 8x ) = 2x-x+7x , 7x+x+0×y , 5(2x)-2x

second one (equivalent to 4x+3y) = 2x+2y+2x+y , 4x+4y-y

third one = every expression left but 2x+2y+2x .

you have to calculate them ! for example look at the first one ----> y+3x-y+9 is equivalent to 3x+9 'cause y-y = 0 ,so 3x +9 will be the left expression and you can't calculate it because the both left items in expression are not from the same type , one of them has a x but the other one doesn't have .

or for example the second one is 2x-x+7x and you know that -x can be written as -1x ,so it becomes like 2x+-1x+7x = 8x .

in the above example we could calculate numbers 'cause all of them have the same variable .

hope it was kinda helpful , sorry for bad english :D

ask me if you have further questions .

Answer:

the diameter is twice the circle radius, or 20

Step-by-step explanation:

Recall that the radius is half the diameter <=> the diameter is twice the radius.  In this problem we need to find the radius first, then multiply it by 2 to obtain the diameter.

We need to determine the distance between the center of the circle Q(6, -4) and the point R(14, 2) on the circle.  

The Pythagorean Theorem applies here.  Going from Q to R, x changes from 6 to 14, or 8 units, which is the horizontal leg of a right triangle, and y changes from -4 to 2, or 6 units.  Thus, according to the Pythagorean Theorem, the length of the hypotenuse of this triangle is

r = √(6² + 8²) = √100 = 10

and so the diameter is twice that, or 20.

Answer:

9.16

Step-by-step explanation:

4.58/.5

Answer:

9.16

Step-by-step explanation:

4.58

--------

0.5

45.8

--------

5

5 into 45 is 9

9 x 5 = 45

45-45= 0

5 into 8 is 1

1 x 5 = 8

8 - 5 = 3

Bring down the zero: 30

5 into 30 is 6

5 x 6 = 30

30 - 30 = 0

the solution for long division of 4.58

                                                    -------- = 9.16

Answer:

There is a 20% chance you draw an orange candy.

Step-by-step explanation:

4+1+2+3=10

pink=4/10

blue=1/10

orange=2/10

white=3/10

There is a 20% chance you draw an orange candy.

Answer:

Step-by-step explanation:

P(O)=2/(4+1+2+3)

P(O)=2/10

P(O)=1/5

P(O)=0.2 (as a decimal)

-7t+3>-46

Subtract 3 on both sides to cancel it out.

-7t+3>-46

    -3  -3

-7t>-49

Now divide -7 on both sides.

-7t>-49

/-7  /-7

t>7

This means the answer, or t, can be anything above 7.

Answer:

13 degrees warmer

Step-by-step explanation:

Answer:

13 degrees Fahrenheit.

Step-by-step explanation:

The temperature started at -1 then raises to 12.

So, it goes -1,0,1,2,3,4,5,6,7,8,9,10,11,12, so it increases by 13 degrees Fahrenheit.

Answer:

The answer is A. 1101000

Step-by-step explanation:

Step 1) Divide 104 by 2 to get the Quotient. Keep the Whole part for the next step and set the Remainder aside.

Step 2) Divide the Whole part of the Quotient from Step 1 by 2. Again, keep the Whole part and set the Remainder aside.

Step 3) Repeat Step 2 above until the Whole part is 0.

Step 4) Write down the Remainders in reverse order to get the answer to 104 as a binary.

Here we will show our work so you can follow along:

104 / 2 = 52 with 0 remainder

52 / 2 = 26 with 0 remainder

26 / 2 = 13 with 0 remainder

13 / 2 = 6 with 1 remainder

6 / 2 = 3 with 0 remainder

3 / 2 = 1 with 1 remainder

1 / 2 = 0 with 1 remainder

Then, when we put the remainders together in reverse order, we get the answer. The decimal number 104 converted to binary is therefore:

A. 1101000

Answer:

It would take them  [tex]\frac{110}{21}[/tex] or approximately 5.24 hours together

Step-by-step explanation:

Use the algebra work formula, [tex]\frac{1}{tb}[/tex] = [tex]\frac{1}{t1}[/tex] + [tex]\frac{1}{t2}[/tex], where tb is the time together, t1 is the time of one person individually, and t2 is the time of the other person.

Plug in 10 and 11:

[tex]\frac{1}{tb}[/tex] = [tex]\frac{1}{t1}[/tex] + [tex]\frac{1}{t2}[/tex]

[tex]\frac{1}{tb}[/tex] = [tex]\frac{1}{10}[/tex] + [tex]\frac{1}{11}[/tex]

Find the common denominator, then add the fractions together:

[tex]\frac{1}{tb}[/tex] = [tex]\frac{11}{110}[/tex] + [tex]\frac{10}{110}[/tex]

[tex]\frac{1}{tb}[/tex] = [tex]\frac{21}{110}[/tex]

Cross multiply and solve for tb:

110 = 21tb

5.24 = tb

So, it would take them [tex]\frac{110}{21}[/tex] or approximately 5.24 hours together

Answer:

B) 16

Step-by-step explanation:

If you look at the graph and go to 4 hours, you can see a dot at 14. So, in this case the nearest answer choice to 14 is 16, as it would be your best estimate if you follow the imaginary line you can draw in the middle of all that points.

Answer:

1000 cm^3

Step-by-step explanation:

First, Find the side length of the cube. The surface area is all the area on the surface of a 3-dimensional object. Since a square has 6 congruent faces the formula for surface area is 6s^2 where s is the side length. Since we know the surface area we can solve for the side length.

600=6s^2- DIvide by 6

100=s^2- Take the square root of both sides.

10=s

The volume of a cube is s^3.

10^3=V

1000=V

Answer:

number 3

Step-by-step explanation:

p represents amount of tickets sold at the pre-sale and d represents the amount of tickets sold at the door. If you add p + d, that equals the total amount of tickets sold which is 345 tickets.

So:

p + d = 345

Pre-sale tickets (p) cost $7 while tickets at the door (d) cost $10, and the total amount of money mad is $2550.

So:

7p + 10d = 2550

Answer should be the equations in number 3.

Answer:

-60z^23

Step-by-step explanation:

Answer:

465 miles

Step-by-step explanation:

From the question,

S₁ = d₁/t₁............................... Equation 1

Where S₁ = Speed travels by Perry for the first journey, d₁= First distance traveled by Perry, t₁ = First time taken.

make d₁ the subject of the equation

d₁ = S₁t₁................... Equation 2

Given; S₁ = 55 miles per hour, t₁ = 5.5 hour

Substitute these values into equation 2

d₁ = 55×5.5

d₁ = 302.5 miles.

Also,

d₂ = s₂t₂.......................... Equation 2

Given: s₂ = 65 miles per hour, t₂ = 2.5 hours.

d₂ = 65×2.5

d₂ = 162.5 miles

Hence,

Total distance = d₁+d₂

Total distance = 302.5+162.5

Total disstance = 465 miles
