Give brainliest or at least a thanks please!
Here, you just want to solve for b. because the right side of the equation doesn't have any like terms, you have to factor that b out:
s = ab - bc
s = b(a - c)
divide both sides by (a - c)
s/(a - c) = b is your answer. it's "s" over "a - c" if the formatting is difficult to read

Hey do you need to show your work for these? I found an answer key
Step-by-step explanation:
We need to use law of cosines
c²=a²+b²-2abcos(C)
let x= angle xzy
plugging in what we have the equation looks like
17²=22²+20²-2*22*20*cos(x)
289=484+400-880cos(x)
.676136364=cos(x)
x=47.45754235
b.)
The smallest angle should be opposite to the smallest side
Using the law of cosines again we get
9²=13²+17²-2*13*17*cos(x)
81=458-442cos(x)
.852941176=cos(x)
x=31.46697634
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
X = -7^3

Answer:
C = 60t + 70
Step-by-step explanation:
The total cost of hiring Plumbing Service is given by the equation C = 50t + 70, where C is the total cost in dollar and t is the time in hours.
So, $ 70 is the fixed price and $50 is the rate of charge per hour for the service.
Now if in the next month the rate of charge per hour for the service increased to $60 and the initial charge remains the same then the equation for the total cost of hiring Plumbing Service will become C = 60t + 70. (Answer)
