Step-by-step explanation:
1/2x+2−1/6x=1/6x−1−1/6x
1/3x+2=−1
1/3x+2−2=−1−2
1/3x=−3
3*(1/3x)=(3)*(−3)
x=−9 <- ANSWER
Answer:
Trevon is 28 years old
Step-by-step explanation:
Riggs =x
Trevon =7+x
7+x+x=49
7+2x=49
2x=49-7
2x=42
x=21
Trevon is 21+7= 28 years old
Answer:
d) (3, 4), (5, 5), (5, 2)
Step-by-step explanation:
<em></em>
<em>We are asked to determine which orderpair in the option has the range of {2,4,5}</em>
Using the definition of range:
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
So in the given options if we write the relation in the form of (x,y) then 4, 5, 2 are the values in the range
The value of x from the given equation is 5/3
<h3>How to determine the value</h3>
Since the three points are collinear to U, they are on a straight line which equals 0
Then we have,
UM + UD = MD
5x+30 + 10x+20 = 3x+80
Collect like terms
5x + 10x + 50 = 3x + 80
15x - 3x = 80 - 50
12x = 30
x = 30/12 = 15/6 = 5/3
Thus, the value of x from the given equation is 5/3
