HELP!!!! Choose the correct answer. Which expression, when evaluated,

blagie [28]

We will check each options and verify it

(a)

$18-2m$

we can plug m=2

$18-2\times 2$

$18-4$

$14$

so, this is FALSE

(b)

$7x-\frac{x}{3} >19$

we can plug x=3

$7\times 3-\frac{3}{3} >19$

$21-1 >19$

$20 >19$

so, this is TRUE

(c)

$6x-1>4x+5$

we can plug x=3

$6\times 3-1>4\times 3+5$

$18-1>12+5$

$17>17$

so, this is FALSE

(d)

$2x^2-3x+1$

now, we can plug x=2

$2(2)^2-3(2)+1$

$8-6+1$

$3$

So, this is FALSE

Simplify.<br> (-3.9) + (6.01) - (-7.423)<br> -5.513.<br> 2.487.<br> 9.533.

lianna [129]

First, since we must follow PEMDAS, we need to do the operation that is first, which is addition.

-3.9 + 6.01 ← Adding a negative means subtracting, then giving the sign of the bigger number.

So now we solved those and we got this answer: 2.11

Now, we need to subtract and re-write the expression.

2.11 - (-7.423) = 2.11 + 7.423= 9.533

Ok....so now we have our final answer, and we have the choices above.

The only answer that matches ours is the last one.

Final answer: 9.533

Hope I helped ^_^
