A: $\frac{5}{3} = \frac{N}{12}$
Multiply both sides by 12
Answer: $N = 20$

B: $\frac{7}{2} = \frac{42}{N}$
Multiply both sides by 2, $7 = \frac{84}{N}$
Multiply both sides by N, $7N = 84$
Divide both sides by 7,
Answer: $N=12$

C: $\frac{N}{2}= \frac{50}{N}$
Multiply both sides by 2, $N = \frac{100}{N}$
Multiply both sides by N, $N^{2} = 100$
Simplify,
Answer: $N = 10 , -10$

Hope I helped you!

What is the solution to the trigonometric inequality 2-3cscx) > 8 over the interval 0 5x52x radians

Sholpan [36]

Answer:

The solution to the inequality is

x > 2π

Step-by-step explanation:

Given the inequality :

2 - 3cscx > 8

We want to find the solution to this.

2 - 3cscx > 8

-3cscx > 8 - 2

-3cscx > 6

cscx < -2

But cscx = 1/cosx

1/cosx < -2

cosx > -1/2

x > arccos(-1/2)

x > 2π

What is the solution of 7x + 14 - 3x = 30? O A. 4 o B. -11

max2010maxim [7]

X = 4

7(4)+14-3(4)=30

7(-11)+14-3(-11)=-30

So, 4 is the answer because when substituted for X, it gives you 30.
