Answer: -406

Step-by-step explanation:

We have the following expression:

$\frac{e}{4}+2f-34e+2f-3$

In addition we know:

$e=12$ and $f=\frac{1}{2}$

If we substitute this in the expresion, we will have:

$\frac{12}{4}+2(\frac{1}{2})-34(12)+2(\frac{1}{2})-3=-406$

X+2(x+3(x+4(x+5)))=153

Allushta [10]

Answer:

$x=1$

Step-by-step explanation:

Here first open the inner parentheses and use the distributive property,

$4(x+5)=4x+20\\\\(x+4(x+5))=(x+4x+20)=(5x+20)\\\\3(x+4(x+5))=3(5x+20)=15x+60\\\\(x+3(x+4(x+5)))=(x+15x+60)=16x+60\\\\2(x+3(x+4(x+5)))=2(16x+60)=32x+120\\\\x+2(x+3(x+4(x+5)))=x+32x+120=33x+120\\\\\\Hence\ x+2(x+3(x+4(x+5)))=x+32x+120=33x+120\\\\\Rightarrow 33x+120=153\\\\33x=153-120\\\\33x=33\\\\x=1$
