Answer:
D) Commutative property of addition
Step-by-step explanation:
Commutative property of addition
a + b = b + a
On this case
-12 + 5x = 5x - 12

Answer:
(D) 9/5
Step-by-step explanation:
One way to work this problem is to find % per cup for cereal and cups per % for milk, then multiply the product of those by 2.
The way we'll use here is to find the ratio of cups of milk to cups of cereal for the same % RDA.
We're given an amount of milk that has 25% of the RDA, but we want to find an amount that has 15% RDA. That amount of milk will be ...
(15%)/(25%)(1 cup milk) = 3/5 cup milk
This tells us that 3/5 cup milk has the same %RDA as 2/3 cup cereal. That ratio is ...
milk/cereal = (3/5)/(2/3) = (3/5)(3/2) = 9/10 cup of milk per cup of cereal
Then for 2 cups of cereal, we need ...
(9/10)(2 cups cereal) = 9/5 cups milk . . . . matches choice D
First number is (n)
second number is (n - 4) --- first number diminished by 4
third number is (4n) --- 4 times the first number
Answer: 6x=42
Explanation: After the step 6x+6=36, it’ll equal 6x=30 because when you subtract the 6 on both sides, it’ll equal 30, revealing it’s actually 6x=30, with the conclusion of x=5.
Answer:
Multiplying and dividing fractions are essentially the same process which you multiply the numbers straight across and no need for common denominators. Except in division of fractions, the second fraction is flipped so that the denominator is on the top and the numerator is on the bottom (reciprocal).
