If I understand correctly, just substitute 15 for C in f = 1.8c + 32, then solve for F
-------------------
f=(1.8)(15)+32
------------
Simplify
f=(1.8)(15)+32
f = 27 + 32
f = 59 is your answer

Golfer had the lowest number of strokes per hole is Alicia  = 4.

Step-by-step explanation:

We have , Three different golfers played a different number of holes today. Rory played 999 holes and had a total of 424242 strokes. Alicia played 181818 holes and had a total of 797979 strokes. Rickie played 272727 holes and had a total of 123123123 strokes. We have to find , Which golfer had the lowest number of strokes per hole :

Rory:

Number of strokes per hole = $\frac{424242}{999} = 425$

Alicia:

Number of strokes per hole = $\frac{797979}{181818} = 4$

Rickie:

Number of strokes per hole = $\frac{123123123}{272727} = 451$

∴ Golfer had the lowest number of strokes per hole is Alicia  = 4.

Who's is the solution set of the compound inequality 3.5x-10>-3 and 8x-9<39

velikii [3]

3.5x-10>-3 add 10 to both sides

3.5x>7 divide both sides by 3.5

x>2

... now for the other inequality:

8x-9<39 add 9 to both sides

8x<48 divide both sides by 3

x<6

So we have x>2 and x<6, so the compound inequality is:

2<x<6 and this means that the solution set is:

x=(2, 6)
