Answer:
Step-by-step explanation:
Step 1: Sum of angles on a straight line is 180
Step 2:
2x + 25 + y = 180
2x + y = 180 - 25
2x + y = 155 (1)
Step 3:
3x - 10 + y = 180
3x + y = 180 + 10
3x + y = 190 (2)
Step 4: Substract equation 1 from 2
3x + y - 2x - y = 190 - 155
x = 35
Step 5:
Substitute x in equation 1 to find y
2x + y = 55
2(35) + y = 155
70 + y = 155
y = 155 - 70
y = 85
Answer:
I. x + y = 9
II. x = 3
III. y/c = 1/4 --> y = 1/4*c
II and III in I
3 + 1/4*c = 9 --> c = 24
Answer:
1/8
Step-by-step explanation:
Probability of pulling a nickel the first time: 5/10
Probability of pulling a nickel the second time: 5/10 (remember that you are replacing)
Probability of pulling a dime the third time: 5/10
Total probability: 5/10 * 5/10 * 5/10 OR 1/2 * 1/2 * 1/2 = 1/8
im pretty sure this is the answer! i hope this helps! <3
