Answer:
a ratio of cats to dogs is 5:3 so the total of that ratio is 8 so for every 8 animals there are 5 cats so 5/8*104=65
b. ratio of dogs to cats is 3:5 so 3 of every animal is a dog so 3/8*104 =39
and 39+65=104 as a final check = 104
this also proves that dogs are better than cats
Step-by-step explanation:
Answer:
its simple just add all of the numbers and then divide it by the total frequency
Step-by-step explanation:
<u>4+5+5+7+8+8+8+10+10</u>
8
=<u>65</u>
8
=8.125
Answer: x = 15, 95 degress, 85 degrees
Step-by-step explanation:
(2x + 65) + (3x+40) = 180
5x +105 = 180
5x = 75
x = 15
2 (15) +65 = 95 deg
3 (15) +40 = 85 deg
2/3 x - 1/5 x = x - 1
Change the fractions to have the same denominators:
10/15 x - 3/15 x = 15/15 x - 1
Simplify the left side of the equation:
7/15 x = 15/15x - 1
Get everything to the right side of the equation:
0 = 8/15 x - 1
Move the (1) to the left side:
1 = 8/15x
Multiply 15 to both sides:
15 = 8x
Divide both sides by 8
15/8 = x
Answer is x=8/15
