Well, since you have the value of b, the first thing you want to do is substitute that value in for b.
5a - 10(3) = 45
10*3 = 30
5a - 30 = 45
Now, to get the variable by itself (a) you have to + 30 because you have to reverse the subtraction.
5a = 75
Now, you divide by 5 to finish getting a by itself.
a = 15

The volume of a cylinder can be found using the formula πr²h.
V = (3.14)(6)²(6)
V = 678.24 cm³
From the answer choices it will be:
V = π(6)²(6)
V = 216π cm³
So the answer is answer choice B.
Hope this helps :)
Given the sequence 5, 6, 7, 8, ....., where x = 1, 2, 3, 4, ...., what is the first term in the sequence?
wel
The first term in the sequence is 5.
<u>Step-by-step explanation</u>:
The sequence is 5,6,7,8,.....
- The first term = 5
- The second term = 6
- The third term = 7
where x= 1,2,3,4,...
The sequence follows the pattern (x+4).
- For x=1, then (1+4) = 5 which is the first term of the sequence.
Similarly,
- For x=2, then (2+4) = 6 which is the second term of the sequence and the sequence follows the same pattern.
Answer:
The graph shows that typically students with more hours of sleep(independent) had higher test scores (dependent)

Look at that website. The part says that (ab*ad)=(ac*ae)
Doing that, we get
9*(9+11x)=10(10+8x)
81+99x=100+80x
19x=19
X=1
