Substitute y = 1/5 x + 1 into x + 5y = -15
x + 5y = -15
x + 5(1/5 x + 1) = -15
x + x + 5 = -15
2x = -20
x = -10
Plug in x = -10 into y = 1/5 x + 1
y = 1/5 (-10) + 1
y = -2 + 1
y = -1
(-10 , -1)
Answer is the last one
(-10 , -1)
9=t/5
times both sides by 5
45=t
12/30=0.4 or 40% finished
18/30=0.6 or 60% did not finish
Using cosine law:
24 ^ 2 = 10 ^ 2 + 16 ^ 2 -2 * 10 * 16 * cos (G)
Clearing we have:
cos (G) = (24 ^ 2-10 ^ 2-16 ^ 2) / (- 2 * 10 * 16)
cos (G) = - 0.6875
Clearing the angle:
G = acos (-0.6875)
G = 133.4325366
Rounding:
G = 133.4
Answer:
G = 133.4
option 4
Answer:
Ethan plays football 18 minutes each day
Step-by-step explanation:
0.6 : 2.5
75/2.5=30
?/0.6=?
0.6 times 30 since you need then to be proportional
=18 minutes each day for ethan
