6 0

Answer:

52.95% (I'd actually round and just go with 53%)

Step-by-step explanation:

Divide 16 by 34, then multiply by 100 to get it to a percent (47.05%). Then you subtract the percent from 100 to find the amount Lizzy got correct (52.95%)

Evaluate this expression <br> (-7--9)*(8+2)

Marizza181 [45]

Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.

P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction

Knowing this, we should start by doing the equations <em>within </em>each parentheses.

$(-7 - -9) *(8 + 2)$
$(2) *(10)$

So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:

$(2)*(10) = 20$

20 is the answer.
