A. 1/4 because numbers 6 and 3 have 2 bigger of a chance than the other numbers, so the spinner is out of 8. Since 3 has double the chance of being landed on than 1,2,4, and 5, than the probability of the spinner landing on the number 3 is 2/8, which is simplified to 1/4
Answer:
d. 1020 students
Step-by-step explanation:
0.1x+18=120
0.1x · 10 + 8 · 10= 120 · 10
x+180=1200
x+180-180=1200-180
x=1020
sorry if im a bit too late
Answer:
<h3>x = 74</h3><h3 />
Step-by-step explanation:
180 = x + x + 32
180 - 32 = 2x
148 = 2x
x = 148 / 2
x = 74
The difference between the coefficients 7 and 3 is 4, so one solution is
y = 1, x = -1.
Then the remaining solutions will be of the form
x = -7n-1
y = 3n+1
for some integer n.
_____
Some of the solutions are (for n=0, -1, -2, 1, 2)
(x, y) = (-1, 1), (6, -2), (13, -5), (-8, 4), (-15, 7)
Domain: (-infinity, infinity)
All linear equations(unless they have restrictions) will have a domain that goes on forever in both directions of the x-axis
