For the order:
Answer the operations and arrange the results. Not a big deal.
_____
(b).
Associative property: a+(b+c)=(a+b)+c
EX:
2+(3+5)=(2+3)+5=10
_________
To find what a variable/ variables mean in an equation, put consonants together and variables together. To transfer something from some side to the other, inverse the operation then make it on both sides
Ex: 2+n=4
4-2 (instead of +2)=n
2=n
ANSWER:
2=10+z/3
2-10=z/3
-8=z/3
-8*3=z/3*3
-24=z
CHECK: 10+-24/3= 2 RIGHT.
What's was the work, now?
_________
Sorry, can't help with the last one.

Order numbers. Basically, either convert to decimals or convert all to fractions over the same denominator. 3+39/40 is bigger than the other numbers.
This is the associative property in action.
Multiply both sides by -3 and collect constant terms. (b)
The equation is an identify if the terms on one side of the (=) is exactly the same as the other side. So combine stuff and find out.

7D^2 - 35D = 0 divide 7 from the two aspects. D^2 - 5D = 0 develop into: D^2 - 5D = D(D - 5) = 0 you are able to examine via employing the distributive belongings this is a(b+c) = ab+ac. now, that's the two D=0, or D-5=0 with the aid of fact something accelerated via 0 equals 0. the respond is D=0 or 5
