Answer:

60 x 130

Step-by-step explanation:

____

| |

w+70 | | w+70

| |

---------

add all the sides

2(w+70)+2w=380

2w+140+2w=380

4w+140=380

move the 140 to the other side of the =

4w=380-140

4w=240

divide both sides by 4

w=60

to get the length plug in 60 to w+70 to get 130 and width is just 60.

Picture 1: the colonists rights had been trampled over by the British, so they renamed the coercive rights and intolerable rights.
Picture 2: the Boston tea party was not appropriate because colonists wasted so much money on that wasted tea, but they had for the motivation to stand up for their right and to risk their life for independence.

I hope this helped! :)

let's firstly, convert the mixed fraction to improper fraction, and then subtract.

$\bf \stackrel{mixed}{2\frac{3}{4}}\implies \cfrac{2\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{11}{4}}
\\\\[-0.35em]
\rule{34em}{0.25pt}\\\\
\cfrac{11}{4}-\cfrac{2}{3}\implies \stackrel{\textit{our LCD will be 12}}{\cfrac{(3)11-(4)2}{12}}\implies \cfrac{33-8}{12}\implies \cfrac{25}{12}\implies 2\frac{1}{12}$
