The quotient of-54 and 9, subtracted from 8 times a number, is-18

1 answer:

4 0

The number is: " -3 " .
_____________________________________
Explanation:
_____________________________________
Let "x" be the "unknown number" for which we are to solve.

8x − (-54/9) = -18 ; Solve for "x" ;

→ 8x − (-6) = - 18 ;

→ 8x + 6 = - 18 ;

Subtract "6" from each side of the equation:

→ 8x + 6 − 6 = - 18 − 6 ;

to get: 8x = -24 ;

Divide EACH SIDE of the equation by "8" ; to isolate "x" on one side of the equation ; & to solve for "x" ;

8x / 8 = -24 / 8 ;

to get: x = -3 .

$Steps:$

$\mathrm{Divide}\:\frac{2x^3+4x^2-5}{x+3}:\quad \frac{2x^3+4x^2-5}{x+3}=2x^2+\frac{-2x^2-5}{x+3}$

In the diagram AB=AD and

hammer [34]

Answer:

AC ≅ AE

Step-by-step explanation:

According to the SAS congruence theorem, if two triangles have 2 corresponding sides that are equal, and also have one included corresponding angle that are equal to each other in both triangles, both triangles are regarded as congruent.

Given ∆ABC and ∆ADC in the question above, we are told that segment AB ≅ AD, and also <BAC ≅ <DAC, the additional information that is necessary to prove that ∆ABC and ∆ADC are congruent, according to the SAS theorem, is segment AC ≅ segment AE.

This will satisfy the requirements of the SAS theorem for considering 2 triangles to be equal or congruent.
