Write an expression that shows how to multiply 4×362 using place value and expanded form

Elodia [21]

Separate this into, instead of 4*362, 4*300+4*60+4*2, all of which are much easier to solve than the former problem.
4*300=1200
4*60=240
4*2=8
Add these together now!
1200+240+8=1448

Hope this helps!

Answer:

n = 5
m = 12
m= -14
y =30

Step-by-step explanation:

$n -8 =-3\\\\Collect\:like\:terms\\n = -3+8\\\\Simplify ; -3+8 = 5\\\\n =5$

$-2m=-24\\\\Divide\: both \:sides\:of\:the\:equation\:by\:-2\\\\\frac{-2m}{-2} = \frac{-24}{-2} \\\\Simplify ; -2m/-2 = m , -24/-2 = 12\\\\m =12$

$\frac{m}{2}=-7\\\\Cross\:Multiply\\\\m\times 1 = 2\times -7\\\\m = -14$

$\frac{2}{3}y=20\\ \\\frac{2}{3} y = \frac{20}{1} \\\\Cross\:Multiply\\\\2y\times 1 = 3\times 20\\\\2y = 20\\\\\mathrm{Divide\:both\:sides\:by\:}2\\\frac{2y}{2}=\frac{60}{2}\\\\Simplify\\y = 30$
