Lisa has a rectangular drawing that is 43.5 centimeters by 934 millimeters. How many centimeters of wood framing will she need?

1 answer:

8 0

Lisa's drawing has the following dimensions:
Width=43.5 cm
Length=934 mm

but 1 cm =10 mm
thus
934mm when converted into cm we shall have:
length=93.4 cm

To get the total length of material required to frame the picture, we calculate the perimeter.
P=2(L+W)
P=2(93.4+43.5) cm
P=2(136.9)
P=273.8 cm

The total length of material required will be 273.8 cm

Answer:

x = -10/3

Step-by-step explanation:

−4(x−5)=−7x+10

Use the distributive property to multiply −4 by x−5.

−4x+20=−7x+10

Add 7x to both sides.

−4x+20+7x=10

Combine −4x and 7x to get 3x.
