Answer:
24
Step-by-step explanation:
To find the number of books Jessica has, we can set up the equation x + 2x = 36, where x represents the number of books Andrew has. Solving the equation, we find that Andrew has 12 books, and Jessica has 24 books.
To find the number of books Jessica has, let's assign a variable to Andrew's books. Let's say Andrew has x books. According to the problem, Jessica has twice as many books as Andrew, so she has 2x books. Together, they have 36 books, so we can set up the equation: x + 2x = 36. Combining like terms, we get 3x = 36. Dividing both sides of the equation by 3, we find that x = 12. Therefore, Andrew has 12 books, and Jessica has 2 * 12 = 24 books.

The percentage of his allowance that Clark gave to charity will be 30%.
The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Clark gives 3/10 of his allowance to charity. Then the percent of his allowance that Clark give to charity is given as,
P = (3/10) x 100
P = 0.30 x 100
P = 30%
The percentage of his allowance that Clark gave to charity will be 30%.

Answer:
Subtract ax from both sides. ax + by − ax = c − ax.
Simplify. by = c − ax.
Divide both sides by b ; b ≠ 0. by b = c b − ax b ; b ≠ 0.
Simplify. y = c − ax b ; b ≠ 0.
It's the parallelogram. Therefore
ML = JK, JM = KL, m∠L = m∠J, m∠M = m∠K and m∠M + m∠L = 180°.
ML = 21 → JK = 21
JM = 29 → KL = 29
m∠L = 127° → m∠J = 127°
m∠M + m∠L = 180° → m∠M + 127° = 180° → m∠M = 53°
m∠M = 53° → m∠K = 53°
