Answer:
C; Substitution property
Step-by-step explanation:
Here, we want to find the justification that justifies the written equation;
If PQ + RS = PS
and RS = XY
then PQ + XY = PS
What we simply did is to substitute RS for XY in the second equation;
The correct answer is Substitution property
It can be fully referred to as the substitution property of equality.
What it simply means in a nut shell is that since XY and RS are equal, then in any addition or arithmetic equation, we can make a substitution of XY for RS since they are equal to each other
Simplifying
8a + 12b = 92
Solving
8a + 12b = 92
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-12b' to each side of the equation.
8a + 12b + -12b = 92 + -12b
Combine like terms: 12b + -12b = 0
8a + 0 = 92 + -12b
8a = 92 + -12b
Divide each side by '8'.
a = 11.5 + -1.5b
Simplifying
a = 11.5 + -1.5b
Answer:
The nearest whole is 122.99 repeated
Step-by-step explanation:
This is the concept of arithmetic, the total distance that Latasha will be from the airport will be:
distance= sum of distances traveled.
hence we shall have:
distance=80+50+40+95
=265 miles
This implies that Latasha is 265 miles off the starting point.
