Answer:
104, 76, 104
Step-by-step explanation:
The measures of the adjacent angles of a parallelogram always add up to be 180 degrees (they are supplementary).
The true solution to the system of inequities shown is B; All values that satisfy
are solutions.
<h3>What is a system of inequalities?</h3>
When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalities.
A collection of inequalities for which we consider a common solution for all inequalities is called a system of inequalities.
If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true.
A set of such values is called a solution set to the considered equation or inequality.
The true solution to the system of inequities shown is B;
All values that satisfy
are solutions.

Answer:
I haven't learn this yet but maybe try asking desmos that app helps me a lot!
Let x represent the price they charge hardcover book and let y represent the price they charge for a paperback book.
4x + 10y = 62 . . . . . (1)
5x + 7y = 61 . . . . . . (2)
(1) x 5 ⇒ 20x + 50y = 310 . . . . (3)
(2) x 4 ⇒ 20x + 28y = 244 . . . . (4)
(3) - (4) ⇒ 22y = 66
y = 66 / 22 = 3
4x + 10(3) = 62
4x = 62 - 30 = 32
x = 32 / 4 = 8
Therefore, the price for a hardcover book is $8 and the price for a paperback book is $3.
