Answer:
(a, b) = (-2, -1)
Step-by-step explanation:
The transpose of the given matrix is ...
Then the [3,1] term of the product is ...
and the [3,2] term is ...
Both of these terms in the product matrix are 0. We can solve the system of equations by adding these two terms:
(a +2b +4) +(2a -2b +2) = (0) +(0)
3a +6 = 0
a = -2
Substituting for 'a' in term [3,1] gives ...
-2 +2b +4 = 0
b = -1
The ordered pair (a, b) is (-2, -1).
JKL is similar to PQR
so they want PR
JKL is similar to PQR
So PR is similar to JL
And they also give us the sides KL and QR
JKL is similar to PQR
Both of those sides are similar, so we can form a proportion.
Plug in the numbers:
Cross multiply:
Isolate PR
Simplify it
So your final answer is

Hey there!
Let solve this problem step by step :)
1. Convert 20/25 into a decimal. In order to do this, you will need to divide the numerator (the top part of the fraction) with the denominator (the bottom part of the fraction).
So,
as a decimal would be 0.8. (We divide 20 by 25)
2. Now, we take the decimal and multiply it by 100. To make it even simpler, just move the decimal, two places to the right. This makes it the percent. So,
0.8 ----> 80%
The final answer is 80%
Thank you!
