Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:
Since both expressions are equal to y, you have to equal both expressions like this:
Now you can solve the equation:
Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result
So, the answer is x=10 and y=-1
Answer:
I=$ 198
Step-by-step explanation:
I=PRT
P=1200
T=3
R=5.5% = 0.055
I=1200*0.055*3= 198
Answer:
100
Step-by-step explanation:
The statement Tell us: a=2 b=5
We have
(a*b)^2=(2*5)^2=(10)^2
Finally we have:
10*10=100
