konstantin123 [22]

Answer:

Lisa will need $273.8\ cm$ of wood framing

Step-by-step explanation:

we know that

The perimeter of rectangle is equal to

$P=2(b+h)$

In this problem we have

$b=43.5\ cm$

$h=934\ mm$

convert to cm

Remember that $1\ cm=10\ mm$

$h=934\ mm=934/10=93.4\ cm$

substitute the values and solve the perimeter

$P=2(43.5+93.4)=273.8\ cm$

lilavasa [31]

Write a system of equations and solve.

x + y = 10
5x + 10y = 90

Multiply and combine equations

-5x - 5y = -50
5x + 10y = 90
------------------
5y = 40
y = 8
x = 2

There are 2 nickels and 8 dimes in the jar. Hope this helps! :)
