Answer:
With what?
Step-by-step explanation:
A + b + c = 12
c = (a + b) - 2.....c - a - b = -2
3a + 1 = 2c
add the first 2 equations
a + b + c = 12
-a - b + c = -2
------------------add
2c = 10
c = 5 <== longest side is 5
sub in 5 for c in the 3rd equation
3a + 1 = 2c
3a + 1 = 2(5)
3a + 1 = 10
3a = 10 - 1
3a = 9
a = 3 <== shortest side
now sub in 5 for c and 3 for a back into the first equation
a + b + c = 12
3 + b + 5 = 12
b + 8 = 12
b = 12 - 8
b = 4 <== other side
I assume the question is to calculate how much work is left to complete.
we know that
the 100% of the work is equal to 1
so
To find how much work is left to complete
therefore
the work completed is equal to 
the pending work to be completed is 
the total work is equal to 
Answer:
94
Step-by-step explanation:
(Lo siento, español no es mi primero lingua, pero intentaré mi mejor :) )
La ecuación is (66 + 90 + x + 94)/4 = 86
Multiple los dos de los lado por 4.
66 + 90 + x + 94 = 344
Hace 66 + 90 + 94, y ponelos a la otro lado con sustracción.
X = 94
94 es la tercera lecture.
