Answer:
8
Step-by-step explanation:
step 1.
1,1,1,1,1,1,1,1 = 2 + 2 + 2 + 2 = 8
2 + 2 + 2 + 2 + 2 = 10
3 + 0 = 3
4 + 4 = 8
5 + 0 = 5
6 + 0 = 6
Step 2.
8 + 10 = 18
18 + 3 = 21
21 + 8 = 29
29 + 5 = 34
34 + 6 = 40
40/6 = 8
This is because if you added 6 + 6 eight times, you would get 40.
Answer:
it has 1200
Step-by-step explanation:
because 900+300=1200
Since the angle is connected to the center of the circle, that makes it a central angle. The 30° angle is the same as arc AYB. so AYB is 30°
Answer:
<em>Part A</em>: Explain why x = 5 makes 4x - 1 ≤ 19 true but not 4x - 1 < 19
<em>Part B: x=9</em>
Step-by-step explanation:
<u>Part A</u>: Because the first one is less than or equal to 19 and the other is just less than.
x = 5
TRUE: 4x - 1 ≤ 19 = 20-1 ≤ 19 = 19 ≤ 19
19 is less than or equal to 19 so its true
FALSE: 4x - 1 < 19 = 19 < 19
19 is not greater than 19
<u>Part B:</u>
5x + 2 = 47 subtract 2 from both sides
5x = 45 divide both sides by 5
x = 9
To check we can plug it back in
5x + 2 = 47
5(9) + 2 = 47
45 + 2 = 47
47 = 47
TRUE
