600/800 descansos porque mencionaste que se toma un descanso cada 3 cm pero se desliza 1 cm cada vez que se toma un descanso, así que solo cambia los 2 ma cm, que es 200 veces eso a 3 o 4 y obtendrás el número de descansos (acabo de adivinar)
Answer:
189 minutes or 3 hours and 9 minutes
Step-by-step explanation:
Given:
12 rectangular planks
2 sides per plank
Length = 8 ft
Width = 3 ft
Area of a rectangle = Length * Width.
A = 8ft * 3ft
A = 24 ft²
24 ft² x 2 sides of a plank = 48 ft²
48 ft²/plank * 12 planks = 576 ft² is the total area Alex needs to varnish.
576 ft² ÷ 125 ft² = 4.608 pint or round to 5 pints
5 pints x $3.50/pint = $17.50 Total cost that Alex need to spend to varnish all the wooden planks.
Answer:
x = 7 x = -1
Step-by-step explanation:
3|x − 3| + 2 = 14
Subtract 2 from each side
3|x − 3| + 2 -2= 14-2
3|x − 3| = 12
Divide by 3
3|x − 3| /3 = 12/3
|x − 3| = 4
Now the absolute value has a positive and negative solution.
x-3 = 4 x-3 = -4
Add 3 to each side
x-3+3 = 4+3 x-3+3 = -4+3
x = 7 x = -1
