I'm assuming you're matching the property you'd use to solve each given equation.
The thing to remember is that when you're solving equations like these, you're going to always do the opposite operations (formally the "inverse" operation) to get the variable by itself.
Equation a: x÷3 = 52
Since this has division connecting the 3 to the x, you'll cancel out the division with multiplication, using the Multiplication property of equality (Property 3).
Equation b: 6x = 36
Since this has multiplication connecting the 6 to the x, you'll cancel out the multiplication with division, using the Division property of equality (Property 4).
Equation c: x+70 = 245
Since this has addition connecting the 70 to the x, you'll cancel out the addition with subtraction, using the Subtraction property of equality (Property 2).
Equation c: x-35 = 450
Since this has subtraction connecting the 35 to the x, you'll cancel out the subtraction with addition, using the Addition property of equality (Property 1).
2,500,000/365 = 6849 per day.
6849/24 = 285 per hour.
285/60 = 4.75 which is rounded to 5.
So 5 per minute

Answer:
<h3>
-2.6m - 5</h3>
Step-by-step explanation:
-(2.6m + 5) = -1(2.6m + 5) = -1•2.6m +(-1)•5 = -2.6m - 5
<u><em>Answer:</em></u>
The missing term is 3x²
<u><em>Explanation:</em></u>
Addition and subtraction can only take place between like terms.
<u>For two terms to be like</u>, both the variable and its degree must be the same in both terms
<u>Now, consider the given terms:</u>
First term is 7x² has the variable x with degree 2
The resulting term is 10x² has the variable x with degree 2
This means that the missing term is ax²
We need to get the value of "a"
<u>This is done as follows:</u>
ax² + 7x² = 10x²
x²(a+7) = 10x²
a+7 = 10
a = 10-7
a = 3
Therefore, the missing term is 3x²
Hope this helps :)
