<span>The
temperature of dry ice is −109.3°f−109.3°f. this is 184.9°f184.9°f less
than the outside temperature. write and solve an equation to find the
outside temperature tt (in degrees fahrenheit).

25% of 15 is the same as 15% of 25
25%=25/100
25% of 15=(25/100)15=(25*15)/100
15%=15/100
15% of 25=(15/100)25=(25*15)/100
Therefore:
25% of 15=15% of 25
because:
(25/100)15=(15/100)25
(25*15)/100=(25*15)/100
3.75=3.75
To answer, we set the expression inside the absolute value symbol (II) equal to 0. That is,
x + 2 = 0
Then, we solve for the value of x.
x + 2 - 2 = 0 - 2
Hence, the value of x from the equation above is equal to -2.
Then, substitute the value of x to the equation and drop the absolute value symbol.
y = 4(x + 2) + 7
Substituting,
y = 4(-2 + 2) + 7
y = 4(0) + 7
y = 7
Thus, the vertex of the absolute value equation is equal to (-2,7). The answer is the last choice.
