Answer:
2s + 30 = 2s
Step-by-step explanation:
Time up hill + time down hill = total time
:
Multiply equation by 30s; results
2s + 30 = 2s
:
The value of 7 is 7 because it is in the ones place
The area of the rectangle is 
Explanation:
One side of the rectangle is 
The another side of the rectangle is 
The formula to find the area of the rectangle is length × width
Area = length × width
Substituting the values, we have,
Thus, the area of the rectangle is
Answer:
The Correct option is C. Addition Property of Equality.
For above Equation by Elimination we use
Addition Property of equality
Step-by-step explanation:
Given:
Addition Property of Equality :
The property that states that if you add the same number to both sides of an equation, the sides remain equal (i.e., the equation continues to be true.)
Here equation is given as
3x + 4y = 38
+ 5x - 4y = -30
-------------------------------------
8x = 8
------------------------------------
Here +4y and -4y gets cancelled or becomes 0 hence 8x = 8.
For above Equation by Elimination we use
Addition Property of equality
Step 1: Find the slope
(y-y)/(x-x) = (8-8)/(9+4) = 0
Step 2: Substitute into the slope intercept equation
y - y = m(x - x)
y - 8 = 0(x - 9)
If the problem just wants plain, slope intercept form, then this is your answer.
If not, y = 8
