Answer:
Kate finished the race in 52 seconds
Alexia finished the race in 58 seconds
Trina finished the race in 49 seconds
Step-by-step explanation:
From this work problem we can set up these series of equations:
First we need to create only one variable in the first equation in order to solve it, so we can substitute in the other equations into the first one. That would look like this
Then we can simplify this
Now that we solve for Kate's time, we can use the other 2 equations to find the times of Alexia and Trina
Using the equation for Alexia's time and plugging in Kate's time gives us
Using the equation for Trina's time and plugging in Kate's time give us
I think 5 cows because rest of 3 cows are not mine if i want i will make all am i right
FOIL stands for first, outer, inner, and last.
So, you multiply the first terms together, the outer terms together, the inner terms together, and then the last terms together.
(b+3)(b-9)
b^2-9b+3b-27 Then simplify
b^2-6b-27
The least possible
value of a would be 60.
