for the first question, start by flipping bot sides upside down. then you will have a 16 dividing the n. we want n by itself, so we have to do the opposite operation the 16 is doing on both sides. that is, we must now multiply both sides by 16. tell us what you get
for the second, multiply both sides by 18 and simplify. what do you get? why do we multiply by 18?
the third question is just like the first. try it. what do you get?
for the last, i don't want to judge, the ruler shown does not allow us to measure accurately i think. is it drawn to scale. you can use a regular ruler to measure the kitchen. whatever answer you get in inches, multiply it by 8 and change the units to feet. that will give you the actual dimensions
haha, they are being graded. my child is taking an online class and asked me for some help. i just wanted to make sure i had the correct answers before i attempted to help her. ;)
You might find the rule of cross-multiplication helpful. If you have
then you may rewrite the equation as
That the simplest thing I've ever met in my life,man!
