If your teacher do not put the value of the q all the letters will be 1 so: 1+5=6 (after you just simplify)
La pregunta requiere que calculemos la diferencia entre la temperatura final e inicial del agua.
Responder:
4 ° C
Explicación paso a paso:
Dado que:
Temperatura inicial del agua = 7 ° C
La temperatura del agua después de 2 horas = 3 ° C
La diferencia de temperatura del agua;
Temperatura inicial - temperatura final
7 ° c - 3 ° c = 4 ° c
La diferencia de temperatura del agua es de 4 ° C
225% 2252/1000 is a fraction so you divide and get 2.25 and move the decimal point over two to the right.
Answer:
x=-6 y=-1
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] y = -x - 7
// Plug this in for variable y in equation [1]
[1] 3x - 2•(-x -7) = -16
[1] 5x = -30
// Solve equation [1] for the variable x
[1] 5x = - 30
[1] x = - 6
// By now we know this much :
x = -6
y = -x-7
// Use the x value to solve for y
y = -(-6)-7 = -1
Solution :
{x,y} = {-6,-1}
