The whiteboards she bought cost $35, and she spent a total of $51.20, subtract to find out the total amount she spent on posters:

\sf 51.20-35=16.2

So she spent a total of $16.20 on posters, now divide by the amount one poster costs to find out how many posters she bought.

\sf 16.2\div 5.4=\boxed{\sf 3}

So she bought 3 posters.

Number 25 someone help me
Fittoniya [83]
The area of a triangle is given by the formula A= \frac{1}{2}Bh, where B is the base and h is the height. We can rearrange this formula to solve for B.

\dfrac{A}{ \frac{1}{2}h} = B\\ \\\\\dfrac{2A}{h} = B.

We plug in the given area, 640 square millimeters, and the given height, 32 millimeters.

B= \dfrac{2(640)\ mm^2}{32 \ mm} = 40 \ mm.

40 mm is our final answer.
