Answer:
D
Step-by-step explanation:
The expression is 
We can follow the rule of "PEMDAS" here.
PEMDAS = Parenthesis, Exponents, Multiply, Divide, Add, Subtract
So, we first need to deal with Parenthesis. Next,
There aren't any exponents, so we deal with Multiplication of 7 and 3.
Then addition/subtraction.
Hence, the first step, from the answer choices, would be D, multiply 7 and 3
Answer:
7x²sqrt(x)
Step-by-step explanation:
7x^(5/2)
7x^(2½)
7x^(2+½)
7x² × x^½
7x²sqrt(x)
sqrt: square root
A) 31.110
B) 0.110
When rounding to three decimal places, you consider if the number to the right of the third decimal place is less than or greater than 5. If it's less than 5, then the digit in the third decimal place stays the same. If it is greater than or equal to 5, then you round the digit in the third decimal place up by one.

Answer:
x=10
x=30
x=15.3
x=4
Step-by-step explanation:
1/2x+7=27
2x+7=27
2x=20
x=10
5=1x-25
30=1x
30=x
3x+9=54
3x=46
x=15.3
16=5x-4
20=5x
4=x
