Answers

Answer:

11.5

Step-by-step explanation:

We solve using :

Pythagoras Theorem

LM² = MN² + NL²

NL² = LM² - MN²

NL = √LM² - MN²

NL = √14² - 8²

NL =  √(132)

NL = 11.489125293

NL = 11.5

Therefore, the length of NL = 11.5

lowing equation:
5x - 6 = 44. Then solve for x

Answers

Answer:

x = 10

Step-by-step explanation:

Simplifying

5x + -6 = 44

Reorder the terms:

-6 + 5x = 44

Solving

-6 + 5x = 44

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '6' to each side of the equation.

-6 + 6 + 5x = 44 + 6

Combine like terms: -6 + 6 = 0

0 + 5x = 44 + 6

5x = 44 + 6

Combine like terms: 44 + 6 = 50

5x = 50

Divide each side by '5'.

x = 10

Simplifying

x = 10

The library is having a book sale. Hardcover books sell for $4 each, and paperback books are $2 each. If Ayanna spends $26 for 8 books, how many hardcover books did she buy?​

Answers

she bought 5 hardcover books and 3 paperback books
5x$4= $20
3x$2= $6
$20+$6=$26

hope this helped

Answer:

5 hardcover books

Step-by-step explanation:

x + y = 8 ↔ Assume x for hardcover books and y for paperback cover

4x + 2y = 26 ↔ Total cost of 8 books is $26

-2x - 2y = -16 ↔ Multiply Equation 1 by -2 so that the coefficients of y is opposite

2x = 10 ↔ Add the two equations to eliminate y

x = 5 ↔ Divide each side by 2
