What is 40cm 25% of?
The answer is 160cm.
Rachel is 160cm. 160 - 40 = 120.
Lucy is 120cm tall.
Well,
As we can see, the only difference is that the parentheses have moved.
This is an example of the associative property. It is specifically of multiplication, because products are used in this case.
Just as a test, let's see whether they are really equal.
Following PEMDAS, we get:
(2*4)7 = 2(7*4)
(8)7 = 2(28)
56 = 56
They are equivalent.
11+5=16 3x2= 6 8x1= 8 so add it together, 16 + 6 + 8 = 30.
To find the y intercept, you cover x and it's coefficient and then divide -20 by 4 to get -5. To find the x intercept, you cover y and it's coefficient and divide 5 by -20 to get -4. So, x = -4 and y= -5
