Step-by-step explanation:
X= 4-3y/y-5
x(y-5) = 4-3y
xy -5x = 4 -3y
xy+3y = 4+5x
y(x+3)= 4+5x
y = (4+5x)/(x+3)
Answer:
B
Step-by-step explanation:
The diagram basically shows three angles that make up a straight line.
We know the angle of a straight line is 180°.
Since there are three angles, Angle 1, Angle 2, and Angle 3 that make up a straight line, we can write:
Angle 1 + Angle 2 + Angle 3 = 180
3x + 4x + 2x = 180
9x = 180
x = 180/9
x = 20
The correct answer is B
The expression that would represent the total number of students at the summer camp for all three years is (b) 5.5s - 54
<h3>How to determine the expression?</h3>
Let the number of students in 2010 be s.
So, we have:
- Year 2011 = 1/2s i.e. half as many students in 2010
- Year 2012 = s - 54 i.e. 54 students less than 2010
The total number of students is:
Total = s + 1/2s + s - 54
Evaluate
Total = 9s/2 - 54
Rewrite s:
Total = 5.5s - 54
Hence, the expression that would represent the total number of students at the summer camp for all three years is (b) 5.5s - 54

Answer:
Complement: 118°. Supplement: 28°
Step-by-step explanation:
To determine the supplement, subtract the given angle from 180.
180 - 62 = 118
To determine the complement, subtract the given angle from 90.
90 - 62 = 28
