Answer:
1. 10 in / 3 ft
2. 5 min / 1 h
3. 1 kg / 250 g
Step-by-step explanation:
The greatest common factor of this can be solved by looking at the individual parts and splitting it up.
First, we have 28 and 7. Well, thats an easy one. 7 goes into 28 4 times so we are now left with 4 and 1.
We can also write the rest of this like this 4(x*x*y) - 1(x*y*y*y*y*y)
Now, what values are in both equations. We have one x and one y that can be taken out of both.
We end up with 7xy(4x-7y^4)
Answer:
90
Step-by-step explanation:
Order of operations are known as PEMDAS:
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
For the most part you have to follow these rules in order to get the correct answer. For this question you first have to multiply 19 by 4 to get 76. Next you add 35 to the number. The sum of 76 and 35 is 111. You final step is to subtract 21. Your final answer is 90. I hope this helps!
