Commutative property: when you have to solve a sum, it does not matter the order in which you place your addends, since you will always get the same result.
We have then:
((40) + (185)) + (240) = 465
(240) + ((40) + (185)) = 465
answer:
Form 1:
((40) + (185)) + (240) = 465
Form 2:
(240) + ((40) + (185)) = 465
Answer:
y = -5 10/11
Step-by-step explanation:
12(5+2y)=4y-(5-9y)
Distribute
12*5 +12*2y = 4y - 5 +9y
60 +24y = 4y - 5 +9y
Combine like terms
60+24y =13y -5
Subtract 13 y from each side
60 +24y-13y=13y-13y -5
60+11y = -5
Subtract 60 from each side
60+11y-60 =-5 -60
11y = -65
Divide by 11
11y/11 = -65/11
y =-65/11
Change to a mixed number
11 goes into 65 5 times (5*11=55) with 10 left over
y = -5 10/11
8, 10, 12
A helpful equation:
x+x+1+x+2 = 30
Combine like terms
3x + 3 = 30
Subtract 3 from each side
3x = 27
Divide each side by to isolate x
x = 9
x = 9. However, 9 is not an even number. Let’s subtract 1 from 9 to get the first even number.
The first number is 8. The best two even numbers after 8 are 10 and 12.
8 + 10 + 12 = 30, thus this is the sequence.
You want to isolate the variable on one side of the equation so that you can see what it's value is with respect to the other terms
