Answer:
Quedan 153 sillas
Step-by-step explanation:
Primero sabemos que en una sala de teatro tenían 7 filas, y en cada una de esas filas habían 23 sillas.
Entonces, originalmente, el número total de sillas es 7 veces 23:
S = 7*23 = 161
Luego sabemos que quitan 8 de esas sillas, entonces el número de sillas que quedan es la diferencia entre el número original de sillas, 161, y 8, que nos da:
S = 161 - 8 = 153
Quedan 153 sillas
Answer:
28+ 20 = 48 because 48 take away 28 equals 20. so g is 20
Answer:
X=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
6−4x=6x−8x+2
6+−4x=6x+−8x+2
−4x+6=(6x+−8x)+(2)(Combine Like Terms)
−4x+6=−2x+2
−4x+6=−2x+2
Step 2: Add 2x to both sides.
−4x+6+2x=−2x+2+2x
−2x+6=2
Step 3: Subtract 6 from both sides.
−2x+6−6=2−6
−2x=−4
Step 4: Divide both sides by -2.
−2x/−2=−4/−2
