Answer:
PQ = 37 Km
Step-by-step explanation:
let PQ = x , then
PR = x + 15 and QR = 3(x + 15) = 3x + 45
sum the parts and equate to 245
x + x + 15 + 3x + 45 = 245 , that is
5x + 60 = 245 ( subtract 60 from both sides )
5x = 185 ( divide both sides by 5 )
x = 37
then
PQ = x = 37 Km
Answer:
<u>The correct answer is 3.77 strokes as the average score for the ninth hole of the Cottonwood Golf Course.</u>
Step-by-step explanation:
1. To find the average score, we need to know how many strokes the 75 golfers needed to play this ninth hole. For doing that, we will do the following addition, using the frequency data given:
1 x 1 = 1
1 x 2 = 2
32 x 3 = 96
27 x 4 = 108
8 x 5 = 40
6 x 6 = 36
1 + 2 + 96 + 108 + 40 + 36
<u>283</u>
<u>This means that all the 75 golfers scored 283 strokes for playing the ninth hole</u>
2. Now that we know that the total number of strokes was 283, we will do a division for find the average score, using also the number of golfers. For doing it, we will do the following division:
Total number of strokes/ total number of players
<u>283/75 = 3.77</u>
<u>The average score is 3.77. It means that the 75 golfers in average hit 3.77 strokes to play the ninth hole.</u>
Answer:
The other one is -8 this is because the point on the graph is multiplied by 2
Step-by-step explanation:
Step-by-step explanation:
-5x = 10 + 10
-5x = 20
X = 20/-5
X = -4
check :
-5 x -4 =20
20 =20
