Answer:

x = -15/4

Step-by-step explanation:

1 - 4/3x = 1/2(-x + 7)

~Simplify

1 - 4/3x = -1/2x + 7/2

~Subtract 1 from both sides

-4/3x = -1/2x + 5/2

~Add 1/2x to both sides

-2/3x = 5/2

~Multiply -3/2 to both sids

x = -15/4

Best of Luck~

Using Pythagoras:-

x^2 = 6^2 + (sqrt18)^2
= 36 + 18 = 54

x = sqrt54 = 3 sqrt6

The sum of the digits of a three digit number is 19. The second digit is one more than the first digit. The third

Oxana [17]

Answer:

D. 568

Step-by-step explanation:

Let the number is in the form of xyz

Sum of the digits is 19

x + y + z = 19

The second digit is one more than the first digit

y = x + 1

The third digit is two more than the second digit

z = y + 2 = x + 1 + 2 = x + 3

Substitute the values of y and z into the first equation and solve for x

x + x + 1 + x + 3 = 19
3x + 4 = 19
3x = 15
x = 5

Find the value of y and z

y = 5 + 1 = 6
z = 5 + 3 = 8

The number is 568

Find angles EFG pleaseee

Bumek [7]

Answer:

50 degrees.

Step-by-step explanation:

Angle FGE = $180-(7x+18)$ because angles on a straight line add up to 180 degrees.

Angle EFG = $180-38-(180-(7x+18))=6x-10$ (Angles in a triangle add up to 180)

$180-38-\left(-7x+162\right)=6x-10$

$180-38+7x-162=6x-10$

$7x-20=6x-10$

Add 20 to both sides:

$7x-20+20=6x-10+20$

$7x=6x+10$

Subtract 6x from both sides:

$7x-6x=6x+10-6x$

$x=10$

Angle $EFG=6x-10=6(10)-10=60-10=50$

Amanda [17]

Answer:

In short, they are all quadrilaterals.

Step-by-step explanation:

Rectangle:

- Every angle equals 90 degrees

- Opposite sides are equal and parallel

Square:

- Every angle equals 90 degrees

- Opposite sides are equal and parallel

- Diagonals within the square are perpendicular

Parallelogram:

- Opposite sides are equal and parallel

- Opposite angles are equal

- Any two angles next to each other have to equal 180 degrees, since it would be a line

Rhombus:

- Opposite angles are equal

- All sides are equal

- Opposite sides are parallel

- Diagonals within the square are perpendicular

- Any two angles next to each other have to equal 180 degrees, since it would be a line

Trapedzoid:

- There is only one pair of parallel lines

Kite:

- There are two pairs of equal signs

- There are two equal angles

- You can look at it like two equal triangles glued together

Really hope this helped you!
