Answer:

see explanation

Step-by-step explanation:

(1)

She had $11 left from $59,

she therefore spent $59 - $11 = $48

divide $48 by 6 to find cost of one book, that is

cost of book = $48 ÷ 6 = $8

(2)

consecutive numbers have 1 between them

let n, n + 1 and n + 2 be the three numbers. then

n + n + 1 + n + 2 = 102 ( sum of 3 numbers )

3n + 3 = 102 ( subtract 3 from both sides )

3n = 99 ( divide both sides by 3 )

n = 33

The 3 numbers are 33, 34 and 35

33 is the smallest of the three

Adding -49 and -4 and solving

\sqrt{-49-4}\\\sqrt{-53}\\\sqrt{53i}

Someone who actually knows what they doing please ‍♀️
mariarad [96]

Answer:

5/9 (F-32) = 25

Step-by-step explanation:

5/9 (F-32) = C

Multiply each side by 9/5

5/9 * 9/5 (F-32) =9/5 C

F -32 = 9/5 C

Add 32

F -32 +32 = 9/5 C +32

F = 9/5 C +32

We want 25 C to Fahrenheit

F = 9/5 *25 +32

F = 9*5 +32

F = 45+32

F = 77
