Answer:

$\dfrac{19}{840}$

Step-by-step explanation:

The given fraction is:

$\dfrac{1}{168}+\dfrac{3}{180}$

We need to solve it.

The LCM of 168 and 180 is 2520.

So,

$\dfrac{1}{168}+\dfrac{3}{180}=\dfrac{15+3\cdot14}{2520}\\\\=\dfrac{19}{840}$

So, the required answer is equal to $\dfrac{19}{840}$ .

Fifteen more than twice the hours Carla worked last week is the same as three times the hours she worked this week decreased by

lapo4ka [179]

2x-15=3(x-15)
2x-15=3x-45
2x+30=3x
30=x

Let's check this work!

2(30)-15=3(30-15)
60-15=3(15)
45=45

She worked 45 hours each week

*the reason it is 2x-15 and not 15+2x is because "more than" is considered a "turn around word" meaning it is the opposite

Find the equation of a line that passes through (5,-3) and is perpendicular to y = x.

VashaNatasha [74]

We know the slope is -1, because perpendicular line's slopes are always the negative reciprocal. We plug (5, -3) in to get:
-3 = -5 + b
b = 2
So we get C. y = -x + 2.
