This is the symmetric property of equality, and in a more general form it can be written as: if a=b then b=a.
<span>This is not to be confused with communicative property, which says that the order doesn't matter in some operations, such as addition, and can be written as a+b=b+a</span>
Answer:
The length has 9 cube so the length is 9/8 or 1 1/8 ft.
the width has 4 cubes, so the width is 4/8 or 1/2 ft.
The height has 11 cubes, so the height is 11/8 or 1 3/8 ft.
So, the volume of the portion of the security wall that Tim has constructed so far is 99/128 cu ft.
Step-by-step explanation:
Answer:
126
Step-by-step explanation:
Let x be the missing length
The triangles are similar:
● UE/140 = 45/x
From the graph we deduce that:
● UE = 140 - 90 = 50
Replace UE by its value
● 50/ 140 = 45/x
Switch x and 50
● x / 140 = 45/50
45/50 is 9/10 wich is 0.9
● x/140 = 0.9
Multiply 0.9 by 140
● x = 140 × 0.9
● x = 126
9 times 4.25 = 38.25 inches area of a rectangle is length times width
Answer:
X= 31
Step-by-step explanation:
13x- 15= 12x+ 16
-12x -12x
x- 15= 16
+15 +15
x= 16+ 15
x= 31
