Varies directly basically means a multiple of
y = kx
where "k" is the constant of variation. You must solve for this first using the given information.
8 = 42k
8/42 = k
0.19= k
Equation: y = 0.19x
when x = 126
y = 0.19(126)
y = 24
Answer:
CE = 36
Step-by-step explanation:
The opposite sides of a parallelogram are congruent , then
AS = CE , substitute values
2x + 10 = x + 23 ( subtract x from both sides )
x + 10 = 23 ( subtract 10 from both sides )
x = 13
Then
CE = x + 23 = 13 + 23 = 36
Answer:
22.4
Step-by-step explanation:
using altitude theorem, the height of the triangle is 20
let y = height
10/y = y/40
y² = 400
y =
or 20
Now we can us the Pythagorean Theorem to find 'x':
10² + 20² = x²
100 + 400 = x²
x=
≈ 22.4
Answer:
13 marbles in the fourth line.
Hope this is correct!
