Find the value of x for which r || s.
Then find m<1 and m<2.
m<1 = 79- x
m<2 = 94- 2x
< means angle
Answer:
x=15
Step-by-step explanation:
79-15=64
94-30=64
The value of x for which r || s will be 15.
What are Parallel lines?
Parallel lines are those lines that are equidistance from each other and never intersect each other.
Given that;
Lines r and s are parallel to each other.
m ∠1 = 79 - x
m ∠2 = 94 - 2x
Since, Two lines r and s are parallel to each other.
Then, By definition of alternate angles of parallel lines;
m ∠1 = m ∠2
Now, Substitute the given values we get;
m ∠1 = m ∠2
79 - x = 94 - 2x
Subtract 79 both side,
79 - x - 79 = 94 - 2x - 79
- x = 15 - 2x
Add 2x both side,
- x + 2x = 15 - 2x + 2x
x = 15
Thus, The value of x is 15 for which r || s.

k/6 + 8 = 5 what does k=?
Answer:
The answer is k= -18
Step-by-step explanation:
hope this helps
k/6 + 8 = 5
1/6k+8-8=5-8
1/6k=-3
To find I divide both sides by 1/6.
1/6k/1/6=-3/1/6
k= -18
The value of k in the equation k/6 + 8 = 5 is -18.
The given equation is k/6 + 8 = 5 .
We have to find the value of k.
Let us isolate the term with variable k by subtracting 8 from both sides:
k/6+8-8=5-8
k/6=-3
Apply cross multiplication:
k=-18
Hence, the value of k is -18.

Your sister can get $30 per day, d, for selling clothes at the market. But she has to pay $60 at first for renting a stand. You can get $20 per day for helping your neighbor rake lawns. After how many days will your sister earn as much as you?
Answer:
6 days
Step-by-step explanation:
pay 60 = -60
Let d = the number of days
30d - 60 = sister
20d = me
Equation:
30d - 60 = 20d Move 30 to the other side
-30d -30d
-60 = 20d - 30d Combine liked terms
-60 = -10d
-10 -10 Divide

Find the equation of the line thatis perpendicular to y =
contains the point (4,-8).
- 2/3 x
Answer:
y= 3/2x -14
Step-by-step explanation:
The formula to solve this problem is y- y1 = m(x-x1), so plug in the coordinates according to the formula: y-(-8)= m(x-4). Then, find the reciprocal of the slope, which is 3/2. Plug 3/2 to where the slope belongs: y+8=3/2(x-4). Calculate to solve the rest: y =3/2x -14

Answer:
([tex]\frac{2}{3}[/tex], 2 )
Step-by-step explanation:
Given the 2 equations
3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)
6x - y = 2 → (2)
Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is
- 6x - y = - 6 → (2)
Add (2) and (3) term by term to eliminate x
- 2y = - 4 ( divide both sides by - 2 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (2)
6x - 2 = 2 ( add 2 to both sides )
6x = 4 ( divide both sides by 6 )
x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
Solution is ( [tex]\frac{2}{3}[/tex], 2 )
