Answer:
x ≤ 17
Step-by-step explanation:
This is the same as solving an equation, except instead of and equal sign it's an arrow.
We have to evaluate everything in the parenthesis first.
3x - 2 (x + 1) ≤ 15
3x - 2x - 2 ≤ 15
Next, we combine like terms - x's
3x - 2x - 2 ≤ 15
x - 2 ≤ 15
Combine like terms - constants (add 2 to both sides)
x - 2 ≤ 15
<u>x ≤ 17</u>
Ratio of men to women: 21:28, also simplified as 3:4
Ratio of women to the total number of people: 28:49 which is also 4:7
Answer:
Option D. Divide the number of acres by the number of horses
Step-by-step explanation:
Let
x-----> the number of acres for each horse
we know that
------> inequality A
To find the number of acres for each horse, divide the number of acres by the number of horses
so
substitute the value of x in the inequality A
------> is true
therefore
The farmer has enough acreage for 12 horses
So the total for dogs (bottom left box) is 47
17 of them had a cat so the top left box is 17
47-17=30 so 30 have a dog but no cat (left column, middle row)
24 cat but no dog (middle column, top row)
9 no cat no dog (very middle box)
Total no dog= 24 + 9 = 33
Total cat (top right) = 17 + 24 = 41
Total no cat (right column, middle row) = 9 + 30 = 39
Hope this make sense :)
