Answer:
43/70
Step-by-step explanation:
Total number of times spun = 14 + 12 + 16 + 15 + 13 = 70
Total number of times spun that yielded a odd number (1,3,5) = 14 + 16 + 13 = 43
The probability of spinning an odd number = total number of spins that yielded 1,3,5 ÷ total number of spins yielding all values from 1 to 5
= 43 / 70
X − 4y = 7
5x + 9y = 6
5x − 20y = 35 //1st * 5
5x + 9y = 6
5x +9y - 5x + 20y = 6 - 35 //2nd - 1st
5x + 9y = 6
29y=-29
5x=6-9y
y=-1 //1st : 29
5x=6-9*(-1)
y=-1
x=15:5 //2nd : 5
y=-1
x=3
check:
for x=3 and y=-1 there is:
x − 4y = 7 is 3 − 4*(-1) = 7 is 7=7 ok
5x + 9y = 6 is 15-9=6 is 6=6 ok
answer: (3;-1) represents the solution.
Answer:
I think it is 40% (Not sure)
Step-by-step explanation:
First, you want to find out how much percent is in one square. To find that out you divide 5 by 100 because 100 is basically 1 in this situation. 100/5 is equal to 20% so that means any one part (Shaded or not) is 20%. Then add the shaded squared up and you get 40%.

Answer:
B. -4x+5y=40
Step-by-step explanation:
y * 5= (4/5 x + 8) * 5
5y = 4x + 40
-4x + 5y =40
