Answer:
1 3/8 ft.
Step-by-step explanation:
<em>The cabinet's center will be at the same place as the wall's center</em>. The wall's center is at its <em>3 1/8 ft mark</em>. The cabinet's center will also be at the wall's 3 1/8 mark. This means that both sides of the cabinet is <em>1 3/4 around the center line</em> (if my wording is vague, look at the image). So, we have to find <em>3 1/8 - 1 3/4</em>, which is 1 3/8 ft.
Since you know that a square has 4 equal sides then you know the small squares are 4cm on all sides and the big squares are 9cm on all sides.
If 2 and a partial sm sq are next to a 9cm sq then knowing 4*2=8 you can figure out that the other square is split as 1cm and 3cm(1+3=4), 3cm of which is lined up with the width (4cm)of another sm sq which would equal 7cm, these 2 sm sqs line up with the unknown sq whose sides would in turn also be 7cm.
A=l*w, 7*7=49
Answer:Area=49cm^2
Answer:
52
Step-by-step explanation:
Angle A equals 4x+8
Angle B equals 5x-b
and they are vertical angles.
If so, vertical angels are equal. You can set the expressions equal to each other, solve for x, and plug that value back in to solve for A.
4x+8=5x-b
add 3 to both sides
4x+11=5x
subtract 4x from both sides
11=x
Then plug x=11 into 4x+8.
4(11)+8
44+8
52
7/16 = 0.4375
those are the 4 decimal places
We have the system of equations:
3x + 5y = 10
x + 5y = 2 => x = 2 - 5y
__________________
3*(2 - 5y) + 5y = 10
6 - 15y + 5y = 10
-4 = 10y
y = -4/10 = -2/5 => x = 2 - 5*y = 2 - 5*(-2/5) = 2 + 2 = 4
The correct answer is x = 4.
