5(3x − 4) = 1
Which of the following correctly shows the first two steps to solve this equation?
Step 1: 15x − 20 = 1; Step 2: 15x = 21
Step 1: 15x − 4 = 1; Step 2: 15x = 5
Step 1: 8x + 1 = 1; Step 2: 8x = 0
Step 1: 8x − 9 = 1; Step 2: 8x = 10
Answer:
The first choice is the correct answer
Step-by-step explanation:
С
65°
65°
Answer:
50°
Step-by-step explanation:
The missing angle, <C, is an angle on a straight line with the two other angles who measures are 65% each.
Therefore:
65 + 65 + C = 180° (angles on a straight line)
130 + C = 180
Subtract 130 from both sides
130 + C - 130 = 180 - 130
C = 50°
Answer:
Step-by-step explanation:
There are a lot of ifs in this problem. The generator has to be a fair one. Any one of the 11 numbers must be equally likely to happen. Second, the sequence must not be the same each time she turns it on. Assuming both are true, then the numbers she will get are
9 10 11 for one number
9 10 11 for the other number
P(x>8) = 3/11 * 3/11 = 9/121
