What is 19 - 6x = 29
notka56 [123]

Answer:

x = (-5)/3

Step-by-step explanation:

Solve for x:

19 - 6 x = 29

Hint: | Isolate terms with x to the left hand side.

Subtract 19 from both sides:

(19 - 19) - 6 x = 29 - 19

Hint: | Look for the difference of two identical terms.

19 - 19 = 0:

-6 x = 29 - 19

Hint: | Evaluate 29 - 19.

29 - 19 = 10:

-6 x = 10

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of -6 x = 10 by -6:

(-6 x)/(-6) = 10/(-6)

Hint: | Any nonzero number divided by itself is one.

(-6)/(-6) = 1:

x = 10/(-6)

Hint: | Reduce 10/(-6) to lowest terms. Start by finding the GCD of 10 and -6.

The gcd of 10 and -6 is 2, so 10/(-6) = (2×5)/(2 (-3)) = 2/2×5/(-3) = 5/(-3):

x = 5/(-3)

Hint: | Simplify the sign of 5/(-3).

Multiply numerator and denominator of 5/(-3) by -1:

Answer: x = (-5)/3

Please help with this geometry problem please
Sergeu [11.5K]
The slant height is 51 cm. The radius can be found from the Pythagorean theorem:
  r^2 + (24 cm)^2 = (51 cm)^2
  r^2 = (51^2 -24^2) cm^2 = 2025 cm^2
  r = 45 cm

The area of the circular base is
  A = π·r^2 = 2025π cm^2

The lateral area is
  A = πrs . . . . . where s is the slant height
  A = π·(45 cm)·(51 cm) = 2295π cm^2

Then the total area is
  total area = base area + lateral area
  = 2025π cm^2 + 2295π cm^2
  = 4320π cm^2

Convert 9ft -2 1/2in to inches
Mandarinka [93]

we know that


1 ft is equal to 12 in

so

9 ft is equal to

by proportion

\frac{1}{12} =\frac{9}{x} \\ \\ x=12*9\\ \\ x=108 in


therefore


9ft-2\frac{1}{2} in=108 in-2.5 in\\ \\ =105.5 in

105.5 in=105 \frac{1}{2}in

the answer is

105 \frac{1}{2}in
