Show how to find 42×27 using an area model.

melomori [17]

Step-by-step explanation:

First break it down

42= 40 & 2

27= 20 & 7

Then times 40 & 20 to get 800
20 x 2 to get 40
40 x 7 to get 280
7 x 2 to get 14

Find the solution of the following system of equations -5+2y=9 3x+5y=7

Rudiy27

Answer:

$x=-\frac{28}{3}\\\\y=7$

Step-by-step explanation:

Given the system of equations:

$\left \{ {{-5+2y=9} \atop {3x+5y=7}} \right.$

You can pply Substitution method:

First you must solve for "y" from the first equation:

$-5+2y=9\\\\2y=9+5\\\\2y=14\\\\y=\frac{14}{2}\\\\y=7$

Therefore, the second and final step to solve the system of equations is to substitute the value of "y" into the second equation and solve for "x":

$3x+5(7)=7\\3x=7-35\\\\x=-\frac{28}{3}$

An artist uses 18 colors on an art palette to paint a picture. This is 72% of all the colors on the palette. How many colors are

brilliants [131]

Answer:

He actually has 25 paints.

Step-by-step explanation:

This is because you take 18x100(100 is the total % under 72 because 72 is out of 100) that equals 1800. then, you take 1800 and divide it by 72. That is because 72 is the actual number that we already have. You would get 25 after dividing. hope this helps:)
