Commutative property (when dealing with addition) means that you can change the order of the terms without changing the sum, so you could write
y + 3x
hope this helps :)
Answer:
answer= 229/30
Step-by-step explanation:
turn 4/3 into 8/6
5/6+8/6=13/6
6x6=36
13/6+36/6=49/6
49x2=98
4x3=12
98/12+3/12=101/12
101/12+18/12=119/12
108/60+595/60=10 1/20
10 1/20-29/12=7 19/30
Y(y+21) If you think about it you will see that it would most likely be this answer because the product of something is multiplying, and the sum is adding. If this answer is not correct then I am sorry.
Answer: The method of solving "by substitution" works by solving one of the equations (you choose which one) for one of the variables (you choose which one), and then plugging this back into the other equation, "substituting" for the chosen variable and solving for the other. Then you back-solve for the first variable.
Step-by-step explanation:
Subtract -9 from both sides.
x2+6x−(−9)=−9−(−9)
x2+6x+9=0
Factor left side of equation.
(x+3)(x+3)=0
Set factors equal to 0.
x+3=0 or x+3=0
x=−3
Answer:
x=−3
