How do you solve 3(5x-2)+1=25

Delvig [45]

Answer:

x = 2

Step-by-step explanation:

3(5x - 2) + 1 = 25 (Given)

3(5x) + 3(-2) + 1 = 25 (Distributive Property of Equality)

15x + -6 + 1 = 25 (Simplify)

15x - 5 = 25 (Simplify)

15x + 5 + 5 = 25 + 5 (Addition Property of Equality)

15x = 30 (Simplify)

$\frac{15x}{15} = \frac{30}{15}$ (Division Property of Equality)

x = 2 (Simplify)

Maru [420]

Answer:

Option 4

Step-by-step explanation:

Given:

Sinθ = $\frac{15}{17}$

Since, cos2θ = 1 - 2sin²θ

cos2θ = $1-2(\frac{15}{17})^2$

cos2θ = 1 - $\frac{450}{289}$

cos2θ = $\frac{289-450}{289}$

cos2θ = $-\frac{161}{289}$

Therefore, Option 4 will be the answer.
