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).
Answer:
D: 20h + 45 = 165
Step-by-step explanation:
20 for EACH hour means that there's a variable (h) attached to 20 so it has to be 20h
Because of that, we can eliminate choices A and B.
Charges mean that it's ADDED to the price so it has to be 45 PLUS 20h
20h + 45 = 165
Answer:
The African Elephant is 2.27 times heavier than a African Lion.
Step-by-step explanation:
9 × 103 pounds = 927E.
4 × 102 pounds = 408L.
Answer:
For the temperature to be below 32 F, following inequality must be met,

Step-by-step explanation:
Let "t" be the temperature at any time.
General format of a linear equation can be given as,
y= mx + c
Where,
y ⇒ dependent variable ( in this case temperature t)
m⇒ Gradient ( the rate at which the temperature drops)
x⇒ independent variable ( hours )
c⇒ intercept ( this is the starting temperature)
Now we can substitute the given values to the above format to arrive at the equation,

We can re-arrange the equations as ,

=
We can write this as an inequality when t = 32 F
