Answer:

(5, -18)

Brainliest, please!

Step-by-step explanation:

(12, -9)(19, 0)

x distance: 7, y distance: 9

To get the other endpoint, we must apply the opposite.

x distance: -7, y distance: -9

(12, -9)

12 - 7 = 5, -9 - 9 = -18

(5, -18)

Answer:

50%

Step-by-step explanation:

Answer:

  52 minutes

Step-by-step explanation:

Streaming Haunted Cave videos used the battery at the rate ...

  (76% -16%)/(3·30 minutes) = 60%/(90 minutes) = (2/3)% per minute

Playing Top Pop used the battery at the rate ...

  (63% -59%)/(24 minutes) = (4/24)% per minute = (1/6)% per minute

The remaining charge (in percent) after x minutes for Jorge's phone will be ...

  J = 55 -2/3x

The remaining charge for Samantha's phone will be ...

  S = 29 -1/6x

We can find the value of x that makes these equal:

  J = S

  55 -2/3x = 29 -1/6x

  26 = 1/2x . . . . . . . . . . . . . . . add 2/3x -29 to both sides

  52 = x . . . . . . . . . . . multiply by 2

It will be 52 minutes before the two phones have the same battery level.

Answer:

x = 8

Step-by-step explanation

Complimentary angles have a sum of 90*. Thus when adding the two equations together, we must get 90*.

7x + 17 + 3x - 7 = 90                Combine like terms

10x + 10 = 90                           Subtract 10 on both sides

10x = 80                                   Divide both sides by 10

x = 8

Answer:

766?

Step-by-step explanation:

Answer and Step-by-step explanation:

Three Digit Number.

***

Second digit = Last digit

*xx

I multiplied 45 from numbers 1-23, with 22 being the maximum # to multiply to get a 3 digit number that is divisible by 45, and 3 being the minimum # to multiply to get a 3 digit number that is divisible by 45.

Now to check which number it is.

When you multiply 45 by 17, you get 765. This number is supposed to be 1 less than the riddle's number. It also has to have the last 2 digits be the same.

So, lets add one to 765 to see if we solved the riddle.

765 + 1 = 766

766 is the answer!

Step-by-step explanation:

[tex] \frac{27}{5} = \frac{4}{x} \\ 27 \times x = 4 \times 5 \\ 27x = 20 \\ \frac{27x}{27} = \frac{20}{27} \\ x = \frac{20}{27} [/tex]

Answer:

20 and 21

Step-by-step explanation:

424 = 400 + 20 + 4. √400 = 20, as √4 = 2

21² = (20 + 1)² = 400 + 40 + 1 = 441 > 424.

Answer:

a = 3

Step-by-step explanation:

We can start by cross multiplying, which is a method to help solve proportions. We get:

5 * a = 3 * (a + 2)

Now, we can distribute the 3 and solve:

5a = 3a + 6

-3a  -3a

2a = 6

/2    /2

a = 3

Answer:

[tex]a = 3[/tex]

Step-by-step explanation:

[tex]a \times 5=(a+2) \times 3[/tex]

[tex]5a=(a+2) \times 3[/tex]

[tex]5a=3a+6[/tex]

[tex]5a−3a=6[/tex]

Answer:

42 students

Step-by-step explanation:

If 4 students had to travel in cars, then 382 - 4 = 378 students traveled in the buses.  Since there were 9 buses, 378 / 9 = 42.  Therefore, there were 42 students in each bus.

Step-by-step explanation:

In mathematics, factorization or factoring consists of writing a number or another mathematical object as a product of several factors, usually smaller or simpler objects of the same kind. For example, 3 × 5 is a factorization of the integer 15, and is a factorization of the polynomial x² – 4.

Answer:

-2

Step-by-step explanation:

when there are two negative signs directly next to each other, it becomes a positive. Set the equation. Let the unknown number be signified by the variable, x:

6 = x - (-8)

6 = x + 8

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 8 from both sides of the equation:

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

6 - 8 = x

x = 6 - 8

x = -2

-2 is your missing value.

Hey there!

6 = ____ - (-8)

• We’re going to substitute the blank value as “x” because we don’t know the variable is just yet.. it is unknown

x - (-8) = 6

x + 8 = 6

SUBTRACT 8 to BOTH SIDES

x + 8 - 8 = 6 - 8

CANCEL out: 8 - 8 because that gives you 0

KEEP: 6 - 8 because that helps solve for the x-value

x = 6 - 8

6 - 8 = x

x = -2

Answer: -2

Answer:

-7

Step-by-step explanation:

Answer:

10+4x+11=x²-10+10 (add 10 both side)

21+4x-4x=x^2-4x  (substract 4x in both side)

21-21=x^2-4x-21 (substract 21 in both side)

x^2-4x-21=0

x^2+3x-7x-21=0(we can write -4x as (3x)+(-7x)=(-4x)

x(x+3)-7(x+3)=0 (get common factor)

(x+3)(x-7)=0 (get common factor which is (x+3) by both)
