So quotient means divide so 2k/-2.6=12
we know that if we divide a negative by a negative, we will get a positive, and if the signs are diffarent, then the answer will be negative so k must be negative
so 2k/-2.6=12
multiply both sides by -2.6 to get rid of the -2.6 denominator
2k=-31.2
divide both sides by 2
k=-15.6
Answer: 2 numbers are 19 and 39
Step-by-step explanation:
<em>y = x + 20</em>
Equation: x + y + 20 = 78
⇔ x + y = 78 - 20
⇔ x + y = 58
⇔ y = 58 - x
So, we have:
x + 20 = 58 - x ( = y)
⇔ x + x = 58 - 20
⇔ 2x = 38
⇔ x = 19
⇒ y = x + 20 = 19 + 20 = 39
Answer:
No solution
Step-by-step explanation:
Lets start by simplifying everything out, and then try to get all of the x's on one side of the equation.
1/2x + 1/3x - 4 = 5/6(x+6)
Simplify and distributive property
5/6x - 4 = 5/6x + 5
Lets subtract 5/6x from both sides to try and get rid of the x from the right side of the equation. (Now, as you may already see, is we try to get all of the x's on one side of the equation, the x's will cancel out, and we will be left with no solution.)
5/6x - 4 - 5/6x = 5/6x + 5 - 5/6x
Simplify
-4 = 5
Because we ended up with something in the form a = b and a ≠ b, there is no solution. (If a = b, then there would be an infinite number of solutions.)
I hope you find this helpful. Let me know if anything in my answer confuses you. Happy studying.
A/b times b/c is = ab/bc
which can be written as a/c times b/b
anything over itself is 1 so b/b is one
a/b times b/c = a/c
