Answer:
1.) -8 2.) 10 3.) -y. 4.) -3x. 5.) 34a
Step-by-step explanation:
im pretty sure these are right. i don't really know how to explain my answers cause it's a pretty easy concept
To find the measure of the s angle que are going use the cosine law because we know all the sides of the triangule:
s² = r² + t² - 2*r*t * cos(S)
Then solve the equation
s² -r² - t² = -2*r*t * cos(S)
arccos ((s² -r² - t² /-2*r*t)) = S
arccos (((250)² -(850 cm)²-(940 cm)² /(-2* 850 cm*940 cm) = S
14.9 = S
round to the nearest 10th of a degree
15º = S
If you combine the 25 hrs and 17 hours it equals 4 hours then multiply by 9.75$ and you would get a check for $409.50
Answer:
B.) 15 - A = 6
Step-by-step explanation:
The equation shows that Marcella had $15 then bought something (A), and now she has 6 dollars left.
15 - A = 6
