no sorry but it's okay you at least guess

Answer:

x,y =3,-4

Step-by-step explanation:

// Solve equation [1] for the variable  y

 [1]    y = 2x - 10

// Plug this in for variable  y  in equation [2]

  [2]    3x - 2•(2x-10) = 17

  [2]    -x = -3

// Solve equation [2] for the variable  x

  [2]    x = 3

// By now we know this much :

   x = 3

   y = 2x-10

// Use the  x  value to solve for  y

   y = 2(3)-10 = -4

Answer:

  y = 5x² -30x +39

Step-by-step explanation:

Multiply it out and collect terms.

  y = 5(x -3)² -6

  y = 5(x² -6x +9) -6 . . . . . expand the square

  y = 5x² -30x +45 -6 . . . . use the distributive property

  y = 5x² -30x +39 . . . . . . collect terms

_____

The expansion of a binomial square is ...

  (a +b)² = a² + 2ab + b²

In this problem, we have a=x, b=-3.

Answer:

y = 5x² -30x +39

Answer:

5d+3

Step-by-step explanation:

just as you combine regular numbers you can combine terms that have the same variable raised to the same exponent, and 7d-2d=5d. So the equation simplifies to 5d+3

Answer: x = 3

because ΔABC has BD is the bisector of ∠ABC

=> AD/AB = DC/BC

⇔ x/6 = 4/8

⇔ x/6 = 1/2

⇔ x = 6.1/2

⇔ x = 3

Step-by-step explanation:

Answer: x=3

Answer:

x + 14

Step-by-step explanation:

Let's break it down to key terms:

14

more (+)

a number (x)

So 14 more than a number is just adding 14 to x.

x + 14

Step-by-step explanation:

You multiply/divide all the fractions with each other.

Answer:

a = 6

Step-by-step explanation:

120 = 3 + 3(7a - 3)   (by PEDMAS, expand parentheses first by distributive property)

120 = 3 + 7a(3) - 3(3)

120 = 3 + 21a - 9

120 = 21a - 6    (add 6 to both sides and rearrange)

21a = 120 + 6

21a = 126   (divide both sides by 21)

a = 126/21

a = 6

Step-by-step explanation:

120-(3+3*(7*a-3))=0

Step by step solution :

STEP

:

Equation at the end of step 1

120 - (3 + 3 • (7a - 3)) = 0

Pulling out like terms :

3.1 Pull out like factors :

126 - 21a = -21 • (a - 6)

Equation at the end of step

:

-21 • (a - 6) = 0

STEP

:

Equations which are never true:

4.1 Solve : -21 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.2 Solve : a-6 = 0

Add 6 to both sides of the equation :

a = 6

One solution was found :

a = 6

Answer:

Shortest distance = 23/24

Farthest distance = 3 17/24 miles

Step-by-step explanation:

Distance of home from school = 2 1/3 miles

Distance of shop from school = 1 3/8 miles

Shortest distance possible :

(2 1/3 - 1 3/8) miles

(7/3 - 11/8) miles

L. C. M = 24

(56 - 33) / 24

23 / 24 miles

The farthest distance :

(2 1/3 + 1 3/8) miles

(7/3 + 11/8) miles

L. C. M = 24

(56 + 33) / 24

89 / 24

= 3 17/24 miles

Answer:

x = 20

Step-by-step explanation:

6(x-8)=72

6x-48=72

6x-48+48=72+48

6x=120

6x/6=120/6

x = 20

hope it's helpful ❤❤❤❤❤❤

THANK YOU.

Answer: x=20

Step-by-step explanation:

Distribute the 6 to the values in the parentheses

6x - 48 = 72

Add 48 to each side

6x = 120

Divide each side by 6

x = 20

Answer:

90°

Step-by-step explanation:

[tex](\pi /2) * 180 = 90[/tex]

Whenever you are required to transfer from Radians to Degrees, simply multiply the Numerator by 180° (180). Treat the [tex]\pi[/tex] as a variable such as x and y, and divide by the numerator.

Answer:

mIHE should be 133°

Step-by-step explanation:

A line is 180°, so, if you take 47° off you're left with 133.

Giving you an answer of 133°.

Answer:

q = [tex]\frac{8}{3}[/tex]

Step-by-step explanation:

The point of intersection (3, 1 ) is the solution to both equations

Using

y = qx - 7 and substituting x = 3, y = 1

1 = 3q - 7 ( add 7 to both sides )

8 = 3q ( divide both sides by 3 )

[tex]\frac{8}{3}[/tex] = q

Answer:The value of x must be 7 units.

Answer:

5

Step-by-step explanation:

First, you would want to subtract the first nights cost from the bill, which you would get 108. And then you would want to divide 108 by how much it costs to stay additional night, so 108 divided by 27 = 4. But you have to remember to add the first night you stayed so it would be 5. I hope this helps :)

Answer:

4 nights

Step-by-step explanation:

148-40=108

108÷27=4

So, you spent 4 nights at the hotel.
