Answer:1.8
Step-by-step explanation:
Set the equation up as a proportion, where x = the height of the tree in feet
27/x = 4.5/5
cross multiply
(4.5)(x) = (27)(5)
(4.5)(x) = 135
divide the entire equation by 4.5 to isolate x
135/4.5 = 30
x = 30
the tree is 30 ft tall
3-2x<7
Subtract 3 from both sides.
-2x<4
Divide -2 from both sides. (switch the sign because you are dividing a negative number)
x>-2
Question: You have 110 dogs (which is the total amount of dogs/pups) and the ratio of the puppies is 2:3. How many puppies are there?
Add 2 and 3 which adds to 5 (You need to combine all the "pie pieces")
Now, divide 110 by 5

÷

Now multiply 2 and 22

Now multiply 3 and 22

The ratio is 44:66
Answer: There are 44 puppies
