Answer:

It depends on how you interpret the statement.

( x * -7 ) + ( 5 - 2 )

x * ( -7 + 5 ) - 2

Step-by-step explanation:

"a number times negative seven added to five equals two"

Let's set x as our number.

So the statement would translate to:

x * -7 + 5 - 2

To simplify, we might try to organize things by adding some parentheses. But that's when things start to get a little.....dicey.

Depending on how you interpret the original statement, both (x*-7)+5-2 and x*(-7+5)-2 can satisfy the statement.

Herein lies our problem. Which of the two expressions is correct?

Well.....both of them, actually. It just depends on how you're interpreting the statement and what options you have available.

If you can only pick one, but all of the expressions are possible options, then you're kind of stuck.

Eduardo purchased a car for $18,500 with 6.5% sales tax, a freight charge of $450, a registration fee of $155, and an ownership
siniylev [52]

Answer:

17852.5$

Step-by-step explanation:

I already answer this in another part, but here it is againa:

In this case, all you need to do is sum all the amounts and take out the down payment of 2500$

First, the car of 18,500 with the 6.5% sale tax, it would be:

18,500 * (6.5/100) = 1202.5$

18500 + 1202.5 = 19702.5$

Now the charge and fees:

450+155+45 = 650$

Then:

19702.5 + 650 = 20352.5$

Finally, the down payment:

20352.5 - 2500 = 17852.5 $

What is the surface area of the prism?
cestrela7 [59]

Step 1: Find the area of the bases (triangles)

A = 1/2 * base * height

A = 1/2 * 16 * 6

A = 48

48 + 48 = 96

Area of the triangles = 96 cm^2

Step 2: Find the area of the sides (rectangles)

A = base * height

A1 = 16 * 12

A1 = 192

A2 = 10 * 12

A2 = 120

120 + 120 = 240

240 + 192 = 432 cm^2

Step 2: Add the areas together

96 + 432

528 cm^2

Hope this helps!! :)
