Answer:

x= -1 y= -5

There for: (x, y). (-1,-5).

Step-by-step explanation:

Step one:

y=y

5x=9x+4

5x-9x=4

-4x=4

x= -1

Step two:

y=5x

y= 5(-1)

y= -5

Hope u find this helpful

Step-by-step explanation:

y=5x

y=9x+4

Substituting value of x in equation 2

y=9x+4

5x=9x+4

5x-9x=4

-4x=4

so x = -1

again

y=5x

y=5 * (-1)

so y = -5.

Answer:

The percentage of people is 60%

Step-by-step explanation:

The reasoning this is the answer is because you to find the percentage you take the amount which does the thing or the part of the whole which is included in the slection ad you divide it by the total and multiply that by 100 so (2100/3500)*100 and that gives you 60%

Answer:

2x+10+3x-10=90

5x=90

x=18

the answer is 18 because the figure is a rectangle and recatngle angles equal 90

Answer:

Where is I on the square?

Answer:

the answer is certainly A

Answer:

-90

Step-by-step explanation:

Respuesta:

A = 51,167

b = 28,5 pies

c = 45,4 pies

Explicación paso a paso:

C = 90 °

B = 38 ° 50 '

Convertir B a grado

1 ° = 60 '

x ° = 50 '

Multiplicar en cruz:

60x = 50

x = 50/60

x = 0,83333 °

Por lo tanto, 38 ° 50 '= 38 ° + 0.833 ° = 38.833 °

Recordar :

A + B + C = 180 ° (Suma de ángulos en un triángulo)

A + 38.833 + 90 = 180

A + 128.833 = 180

A = 180 - 128,833

A = 51,167 °

Usando identidades trigonométricas, podríamos encontrar byc

Para obtener b:

Tan B = opuesto / adyacente = b / 35.4

Tan 38,833 = b / 35,4

b = Tan 38,833 * 35,4

b = 28,5 pies

Para obtener c:

Podríamos usar:

Sin A = opuesto / hipoteno = 35,4 / c

Sin 51,167 = 35,4 / c

c * sin 51,167 = 35,4

c = 35,4 / sen 51,167

c = 45,4 pies

Answer:

21 ounces of juice.

63 ounces of water

Step-by-step explanation:

let :

x = ounces of strawberry juice to make the strawberry infused water.

3x = ounces of water needed to make the strawberry infused water.

3x + x = 84

4x = 84

divide both sides of the equation by 4

x = 21 ounces

3x = 3 x 21 = 63 ounces

= 118

Answer:

(2.6, 4.8)

Step-by-step explanation:

The midpoint segment formula is expressed as;

M(X, Y) = [(ax2+bx1)/a+b, (ay2+by1)/a+b]

X = ax1+bx2)/a+b

Y = ay1+by2)/a+b

Given X(-1,3) to Z(5,6) and a = 2, b = 3

X = 2(-1)+3(5)/2+3

X =(-2+15)/5

X =13/5

X = 2.6

Similarly;

Y = 2(3)+3(6)/2+3

Y =(6+18)/5

Y =24/5

Y = 4.8

hence the required coordinate of Y is (2.6, 4.8)

6x³(2x - x² + 3)

Step-by-step explanation:

Given

12[tex]x^{4}[/tex] - 6[tex]x^{5}[/tex] + 18x³ ← factor out 6x³ from each term

= 6x³(2x - x² + 3)

Answer:

12 y

Step-by-step explanation:

π. x².y = ⅓. π (½x) ².h

=> eliminate π,

x²y = ⅓. ¼x².h

=> eliminate x²,

y = 1/12 h

h = 12 y

so, height of the cone = 12 y

Answer: 7.5miles

Step-by-step explanation:

Since the fare is calculated as a base charge of $3.00 plus an additional $2.00 per mile traveled and also customary to leave a $2 tip and Max wants to spend exactly $20. This information can be formed into an equation as:

Let the miles that he can travel be m.

3 + (2 × m) + 2 = 20

3 + 2m + 2 = 20

5 + 2m = 20

2m = 20 - 5

2m = 15

m = 15/2

m = 7.5miles

Therefore, Max can travel 7.5miles

He answered 16 questions correctly, and got 3 wrong answers.

==========================================================

Explanation:

Let

x,y,z are nonnegative whole numbers.

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

Since there are 20 questions total, this means the first equation to set up is:

x+y+z = 20

Solving for y leads to

x+y+z = 20

y+z = 20-x

y = 20-x-z

We'll use this later.

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

Another equation to set up is 7x-4y = 100 because Eric earns 7 points per correct answer and loses 4 points for each incorrect answer, and all that leads to 100 points total which was his quiz score. We'll ignore the questions he left blank since they add 0 points.

Let's plug the equation in which we isolated y

7x-4y = 100  

7x-4(20-x-z) = 100

7x-80+4x+4z = 100

7x+4x+4z = 100+80

11x+4z = 180

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

Now we can guess and check to see which pair of x and z values will make that last equation above true. I suggest starting with the smallest possible value of x and using that x value to solve for z.

If x = 0, then,

11x+4z = 180

11(0)+4z = 180

4z = 180

z = 180/4

z = 45

So if Eric got 0 correct answers, then he left 45 questions blank. But that isn't possible because there are only 20 questions total. So we'll ignore the case that x = 0.

If we increase x by 4, and decrease z by 11, then we get another ordered pair solution to this equation

So another solution is (x,z) = (4,34)

Note that

11x+4y = 180

11(4) + 4(34) = 180

But like before, z = 34 isn't possible since 20 is the max.

Increase x by 4 again, and drop z by 11 to get (x,z) = (8,23). Again we run into the same issue as before.

Increase x by 4 again, and decrease z by 11 to get (x,z) = (12, 12). Now we have both x and z smaller than 20, but note how x+z = 12+12 = 24 which exceeds the total number of questions. So we rule this case out as well.

Do another round of "increase x by 4, decrease z by 11" to get to (x,z) = (16, 1). This is the only case left because anything beyond this, z will be negative.

Luckily, this final case does work. If Eric answers x = 16 questions correctly, then he left z = 1 of them blank. That must mean y = 20-x-z = 20-16-1 = 3 questions were incorrect.

We can see that:

7x-4y = 7(16)-4(3) = 112-12= 100

meaning that (x,y) = (16,3) is a solution to 7x-4y = 100.

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

To summarize, we found that the only possible solution is (x,y,z) = (16, 3, 1)

Meaning x = 16 questions were correct, y = 3 were wrong, and z = 1 question was left blank.

Hey there!

7^8

= 7 * 7 * 7 * 7 * 7 * 7 * 7 * 7

7 * 7 = 49

= 49 * 49 * 49 * 49

49 * 49 = 2,401

2,401 * 2,401

= 5,764,801

Answer: 5,764,801
