Answer:
6.3
Step-by-step explanation:
8.5 - (-4.8)
Let's focus on - (-4.8)
if a negative number is subtracted, it reverses itself
In other words, if a negative number is being subtracted, it is the same as being added as a positive number
So we change the equation to
8.5 + 4.8 = 13.3
Now we subtract 7 from 13.3
Since positive 7 is being subtracted, the rule for -4.8 does not apply to it
13.3 - 7 = 6.3
Answer:
y = 4x - 19
Step-by-step explanation:
The line is parallel to the line whose equation is;
y = 4x + 1
Parallel lines have the same slope so the slope of our line is 4.
The line passes through point (5,1)
Slope = change in y ÷ change in x
Taking another point (x,y) on the line,
Slope =
= 4
y - 1 = 4x - 20
y = 4x - 19
Answer:
8(23) so 184
Step-by-step explanation:
The correct answer is the first choice. You can determine which angles are congruent by looking at the corresponding angles (angles that are in the same position) on the similar trapezoids). The angles would be congruent even though the shapes are not the same size.

➷ K - 2L = L - M
Subtract L from both sides:
K - 2L - L = -M
Add M to both sides:
K - 2L - L + M = 0
Add 2L to both sides:
K - L + M = 2L <== this is the answer
