Answer:
(-30, 10)
multiply -20/60 by -0.5 each and you get 10/-30
this is the only pair achievable by proportion.
Answer:
11.4
Step-by-step explanation:
So we know that Triangle ACB is similar to Triangle EFD.
This means that their sides are proportional to each other.
We want to find x or side AB. To do so, we can set up a proportion.
The proportional side to AB is ED. Let's also use BC since we know its value. The proportional side to BC is DF. Thus:
Substitute x for AB, 3.8 for Ed, 15 for BC, and 5 for DF. Thus:
Reduce the right:
Cross multiply:
So, the value of x is 11.4
And we're done!
Step-by-step explanation:
Consider the provided information.
For the proportion method first set up the equation like this:
Perform the cross multiplication and then solve for the missing part.
For example:
Find 80 percentage of 10.
Step 1: Set up the equation.
Step 2: Perform the cross multiplication
Step 3: Solve for the missing part.

Answer:
Hannah got $200 for her mom
Step-by-step explanation:
With the numbers in this question you don't even have to worry about percentages.
You can think of it in quarters:
75% is 3 quarters of 100%
(25% + 25% + 25% + 25%)
$150 is 3 quarters of $200
($50 + $50 + $50 + $50)
Hope this helps and isn't a confusing way of explaining it! :)
