The formula for a cylinder's surface area is :
in this question, h=x.
Let's plug the values in the formula
Answer:
(5, 9)
Step-by-step explanation:
The distance between A and B is 1/3 the distance between A and C.
x coordinates:
3 − 2 = 1/3 (x − 2)
1 = 1/3 (x − 2)
3 = x − 2
x = 5
y coordinates:
-1 − (-6) = 1/3 (y − (-6))
5 = 1/3 (y + 6)
15 = y + 6
y = 9
The coordinates of point C are (5, 9).
Answer:
We can introduce a variable ( a letter representing an unknown ) to help us solve this question.
Let χ = "a number..."
We can rewrite the sentence in the following way:
7( χ + 2 ) = 8
To solve for χ , we can first distribute 7:
7 ∗ χ + 7∗(2) = 8
7χ + 14 = 8 ⇐ since 7 times 2 is 14
Let's get χ by itself first. We do so by subtracting 14 from both sides of the equation:
7χ + 14 - 14 = 8 - 14
7χ + 0 = -6 ⇐
7χ = -6 ⇐
The last number in our way is that 7. Let's divide both sides by 7 ( which is the same as multiplying both sides by 1 / 7 ) to figure out what χ is:
7χ ∗ ( 1 / 7 ) = -6 ∗ ( 1 / 7 )
χ ∗ ( 7 / 7 ) = - 6 / 7 ⇐
χ ∗ ( 1 ) = - 6 / 7 ⇐
χ = - 6 / 7
Therefore ( we can also use ∴ to represent the word "therefore" ) our number in question is -6 / 7
