Answer:
the answer is 5
Step-by-step explanation:
2x/5 - 9 = -7
2x/5 = -7 + 9
2x/5 = 2
2x = 2 * 5
2x = 10
x = 10/2
x = 5
Hey there!
In my opinion, yes, because there are many reasons for this answer. But one reason is that when you get older, you'll be using 3.14 more than 22/7 because you don't really use fractions anymore, you use decimals.
^^That's my opinion, you might have something different^^
Hope this helps!
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 <span>− 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 .

D: -25/27
-5/6 ÷ 9/10 = 5/6 x 10/9 *when diving fractions, use recipricals.*
-5/6 ÷ 10/9 = - 25/27 *just multiply each numerator and denominator*
