Answer:
Don caught 3.6 kg and Dan caught 0.6 kg.
Step-by-step explanation:
Set up a system of equations:
Don's fish is the variable a and Dan's fish is the variable b.
a + b = 4.2 (1)
a=6b (2)
We can substitute a in the first equation using the second equation, so:
6b + b = 4.2
7b = 4.2
b = 0.6 kg
Dan caught 0.6 kg. Then, we can use equation 2 to find how much Don caught.
a = 6 x 0.6
a = 3.6
Don caught 3.6 kg.
Answer:
Csc(0)=24/27 and Tan(0)= 24/7
Step-by-step explanation:
We know that secant is the inverse of cos. So that Sec(x) = Cos^-1(x)= hypotenuse/adjacent. We now know that 25 is hypotenuse and 7 is the length of side adjacent to angle theta.
Given this information we can find the length of side opposite to theta, which has length 24.
Now we know:
Hypotenuse=27
Adjacent=7
Opposite=24
Csc is inverse of sin, so that scs=sin^-1=hypotenuse/opposite=27/24
and tan=opposite/adjacent=24/7
You will need to do the following
You need to get both of the X's on the same side
So you will take the 5x and subtract it to the other side to get
-6=-3x
-3 times 2 = -6 so therefore -6=-6
-6= -3(2)
Answer: X= 2
