Joelle is working on a school report in a word processor. She wants to place an oversized image which is
30.51 cm wide so that it appears centered on the page. The width of the page is
21.59 cm. In the program, horizontal positions to the right of the leftmost edge of the page are positive.
What horizontal position for the left edge of the image should Joelle use to center the image?

answer:

Look below

Step-by-step explanation:

the width of the page 21.59 cm 21point 59 start text space c, m,end text.in the programme,horizontal position to the right of the leftmost edge of the page are positive

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

multiplication is multiplication.   it might feel harder depending on what level of math you are in, but generally it will be the same old stuff, while implementing some new concepts and methods of solving work.
