Answer:
The associative property is being demonstrated. This is because the order of the numbers themselves is not being changed, but the groupings are. The associative property is often confused with the commutative property. In the commutative property, the order of the numbers are changed. Example -
3 + 4 + 7 = 7 + 3 + 4
In this problem, the numbers' order is changed, demonstrating the commutative property.
However, in the problem that you wish to solve, the numbers' order is not changed, but the parentheses around them is changed (also known as the groupings), demonstrating the associative property.
Answer:
15 times as long
Step-by-step explanation:
6 meters/0.4 meters is 15, so it is 15 times as long.
Answer:
25.2X + 3.4 centimeters.
Step-by-step explanation:
The formula for the perimeter of a rectangle
= 2L + 2W
= 2(L + W)
From the question:
Width of a rectangle (W) = 9.7 X - 4.7 centimeters
Length of a rectangle (L) = 2.9 X + 6.4 centimeters
Imputing it into the formula
2(L + W)
2( 9.7X - 4.7 + 2.9X + 6.4)
2 (9.7X + 2.9X - 4.7 + 6.4)
2( 12.6X + 1.7)
= 25.2X + 3.4 centimeters.
Therefore, the perimeter of the rectangle = 25.2X + 3.4 centimeters.
Answer:
0.645
Step-by-step explanation:
since a percent is out of 100, it could also be written a 64.5/100,
then converting a fraction into a decimal is jus dividing the two equaling to 0.645
