This is a help site, so I'll explain each property and see if you can match them yourself.
Associative property of addition, you can add 3 or more different numbers any which way, the sum will be the same.
Commutative Property of Addition - same as the associative property but with 2 numbers.
Identity Property of Multiplication - Any number multiplied by one is itself
Multiplicative Property of Zero: x * 0 = 0
Associative Property of Multiplication - Same as that of addition, yet with multiplication.
Distributive Property: Factoring Out.
EX: (12 x 15) = 3(4 x 5)
50 POINTS!!! Word problem.
A class contributed $8.40 in dimes and quarters to the Red Cross. In all, there was 45 coins. How many coins of each kind were there?
Please also give an explanation. 50 points are a big deal.
Answers
Let q = # of quarters
45 = d + q
.1d + .25q = 8.40
Then we can use the substitution method and make it so that d = 45 - q.
Then plug in the value for d into the second equation.
.1(45-q)+.25(q)=8.40
4.5-.1q+.25q=8.40
4.5+.15q = 8.40
.15q = 3.90
q = 26
d = 45 - 26 = 19
26 quarters
19 dimes
Answer:
Step-by-step explanation:
Let d = # of dimes
Let q = # of quarters
45 = d + q
.1d + .25q = 8.40
Then we can use the substitution method and make it so that d = 45 - q.
Then plug in the value for d into the second equation.
.1(45-q)+.25(q)=8.40
4.5-.1q+.25q=8.40
4.5+.15q = 8.40
.15q = 3.90
q = 26
d = 45 - 26 = 19

Select ALL expressions that are equivalent to -6. *
-7 + 13
-10 - (-4)
26 - 32
16 - 10
3 - ( - 3)
Answers
Answer:
The terms equivalent to - 6 are
- 10 - ( - 4)
26 - 32
Answer:
Only the 2nd and 3rd expressions are equal to -6
Step-by-step explanation:
The only way to do this is evaluating ot actually doing each expression:
Some key skills needed are subtraction with negative numbers, distributing the negative properly, and addition.
The first one is -7+13. This can be rewritten as 13-7. And this is 6, so it is not equal to -6. The 2nd one is -10-(-4). You have to distribute that minus sign after the -10 to the -4. Think of the subtraction symbol I mentioned as -1. -1(-4) is 4 since the negative signs cancel out. It would then be -10 + 4 which -6. So this works. This one is 26 - 32. You have to subtraction here. 26 - 32 is the opposite of 32 - 26. 32 - 26 is 6, so 26 - 32 would be -6. So the 3rd one is another one eqial to -6. This is simple subtraction. 16 - 10 is 6, so this one definitely does not work. This uses the same skill as number 2. Think of the minus sign after the positive 3 as a -1. -1(-3) is 3, so it would be 3 + 3 which is 6.Only the 2nd and 3rd ones work. Hope you understood and have a nice day!!
