3 1/4 = 13/4
2 3/4 = 11/4
13/4 - 11/4 = 2/4 = 1/2
I only know one and i would say that it is the first one .
Y=5/x+3
For the equation of the line expressed as Ax + By + C = 0, the value of the slope (m) is calculated by -A / B. For perpendicular lines, the slope of one should be the negative reciprocal of the other. From the choices given, the lines that are perpendicular is Option A.
I saw this same type of question and page but with different numbers just 5 minutes ago...
Anyway here’s the answers:
1) Complementary
3x+1+44=90
3x+45=90
3x=45
x=5
2) Vertical
Ignore everything about the work. The answer is 120 degrees because they’re vertical angles.
3) Supplementary
15x-5+110=180
15x+105=180
15x=75
x=5
And I can’t see the last question clearly
Answer:
-1 1/2
same as -1.5 but since you are dealing with fractions you should put it in fraction form unless told otherwise.
