6 apartments in 2.5 hours
30 apartments in ? Hours
6/2.5=30/x
6x=(30)(2.5)
x=75/6
x=12.5 hours
Answer:
8
Step-by-step explanation:
n * 12 = 96
96/12 = 8
==> n = 8
Answer:
x3
Step-by-step explanation:
Considering x4 and x3 actually power terms.
I mean: x4 is
and x3 is
.
Let's decompose the first term: 
Now it is clear that the common factor is
.
<u>Given</u> -
- If l || m, m∠1 = (13x + 24)°, and m∠2 = (5x-6)°,
<u>To find</u> -
<u>Concept</u> -
Whenever two parallel lines are cut by a transversal, an interesting relationship exists between the two interior angles on the same side of the transversal. These two interior angles are supplementary angles. Hence, according to the figure l and m are two parallel lines and t is the transversal intersecting them then ∠1 + ∠2 = 180°.
<u>Solution</u> -









m∠2 = (5x-6)° = {5(9) - 6}° = {45 - 6}°= 39°
Henceforth, m∠2 = 39°
we know that
If two lines are parallel, then their slopes are the same
m1=m2
and the y-intercept is unequal
If two lines are perpendicular, then the product of their slopes is equal to -1
m1*m2=-1 or m1=-1/m2
therefore
<u>the answer is</u>
Two non vertical lines have slopes m1 and m2, respectively. The lines are parallel if m1=m2 and the y-intercept are unequal; the lines are perpendicular if m1*m2=-1 or m1=-1/m2.
