Question

When 4[0.5+2.5y-0.7x-1.3+4] is simplified, what is the resulting expression?

Answer 1

Answer:

The resulting expression is:

$4\left[0.5+2.5y-0.7x-1.3+4\right]\:=-2.8x+10y+12.8$

Step-by-step explanation:

Given the expression

$4\left[0.5+2.5y-0.7x-1.3+4\right]\:$

simplifying

$=\left(4\right)\left(0.5+2.5y+-0.7x+-1.3+4\right)$

$=\left(4\right)\left(0.5\right)+\left(4\right)\left(2.5y\right)+\left(4\right)\left(-0.7x\right)+\left(4\right)\left(-1.3\right)+\left(4\right)\left(4\right)$

$=2+10y-2.8x-5.2+16$

$=-2.8x+10y+12.8$

Thus, the resulting expression is:

$4\left[0.5+2.5y-0.7x-1.3+4\right]\:=-2.8x+10y+12.8$
