Joelle is working on a school report in a word processor. she wants to place a figure which is 13.09 cm wide so it apperars centerd to the page. the width of the page is 21.59 cm how much margin should she leave on the left so that the figure is centered?

Hello Croary

We would first need to subtract 13.09cm from  21.59cm which will be 8.5cm, with the left over space, divide in half

8.5/2 = 4.25cm

:)

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

4+3x hope you like mark as brainliest✔
