146° + (-39 +x)° = 180°

Subtract 146° on both sides.

(-39 +x)° = 180° - 146°

(-39 +x)° = 34°

(x - 39)° = 34°

Add 39° on both sides

x = 34° + 39°

x = 73°

Your final answer is C) 73.

Answer:

The correct answer option is $\frac { 4 } { 4 9 }$ .

Step-by-step explanation:

We are to find the probability that both your parents were born on weekend (either Saturday or Sunday).

Total number of days in a week = $7$

Number of days in weekend = $2$

Probability of being born on weekend = $\frac { 2 } { 7 }$

P (both parents were born on weekend) = $\frac{2}{7} \times \frac{2}{7}$ = 4/49

Зn - 3 = 4n + 1 step by step

JulsSmile [24]

Answer: n = -4

3n - 3 = 4n + 1

Add 3 to both sides

3n = 4n + 4

Subtract 4n from both sides

-n = 4

Divide by -1 on both sides

n = -4
