<h3>Answer C is correct</h3>

Step-by-step explanation:

$6x - 2 + 5x + 18 + 2x + 8 = 180 \\ 13x + 24 = 180 \\ 13x = 180 - 24 \\ 13x = 156 \\ \frac{13x}{13} = \frac{156}{13} \\ x = 12 \: \: degrees$

Radda [10]

Answer:

S = v1 t1 = 7 t1 traveling downstream

S = v2 t2 = 5 t2 traveling upstream

7 t1 = 5 t2

7 (6 - t2) = 5 t2 since t1 + t2 = 6

42 - 7 t2 = 5 t2

t2 = 42 / 12 = 3.5 hrs so t1 = 2.5 hrs

S = 7 t1 = 7 * 2.5 = 17.5 mi

Also, S = 5 t2 = 5 * 3.5 = 17.5 mi

Answer:

y-intercept is 30

Step-by-step explanation:

Given the model $y = 10x + 30.$ comparing this model to the equation of a straight lines we can get the y- intercept

$y = 10x + 30\\\y= mx+c$

The y- intercept is 30 which is the constant factor and it describes to us about the one-time registration fee of $30.
