Let
x-------> ounces of <span>ground sumac
y-------> ounces of </span><span>ground thyme
we know that
x+y=25------> x=25-y------> equation 1
1.25x+1.5y=1.35*25-----> 1.25x+1.5y=33.75-----> equation 2
substitute equation 1 in equation 2
1.25*[25-y]+1.5y=33.75------> 31.25-1.25y+1.5y=33.75
0.25y=2.5
y=10
x=25-y-----> x=25-10-----> x=15
the answer is
15 </span>ounces of ground sumac
10 ounces of ground thyme
<span>y = arctan(3) </span>
<span>Since the inverse tangent is a function, there is only one y-value. However, there are infinitely many solutions to tan(y) = 3 (they are arctan(3) + kπ where k is an integer). The approximate value of y here is y = arctan(3) ≈ 1.24905 (in radians).

Answer: 55 miles
Step-by-step explanation: Marcus goal is 80 miles for the week. he has already completed 25 miles of that goal so you would subtract 25 from 80 then you would find the miles still left
80-25=55
Answer:
x = -6
Step-by-step explanation:
-10-x=-4 Add 10 to both sides...
-x=6 Divide both sides by -1...
x=-6
