Answer:
1. $137.75
3. $149.15
Step-by-step explanation:
1.
12.25+125.50=137.75
3. 8.25% of 137.75= 11.4
137.75+11.4=149.15
Solution set is: (
)
Option B is correct
Step-by-step explanation:
We need to find the solution to system of equations
Let:
Putting value of y from eq(2) into eq(1)
So, value of x=7
Putting value of x into equation 1 to find the value of y:
So, value of y = 
Solution set is: ()

Answer:
slope of a line is given by -A/B
Here A=5 and B= -3
so , when we plug in the values: -(5/-3) = 5/3
five thirds lol.
Answer:
The correct order is:
a
c
d
b
Step-by-step explanation:
First, let's write 1/x in a convenient way for us:
a) Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.
Now we assume that 1/x is rational (we want to prove that this implies that x will be also rational and because we know that x is irrational assuming that 1/x is rational will lead to an incongruence), then:
c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠ 0. Observe that p is not 0 either, because 1/x is not 0.
Now we know that we can write x as a quotient of two integers, we need to imply that, then the next one is:
d) Observe that x is the quotient of two integers with the denominator nonzero.
And that is the definition of rational, then we end with:
b) Hence x is rational.
Which is what we wanted to get.
