Andre45 [30]3 years ago

5 0

Quantity Equation: t + s = 20 gallons
Lemon content Eq: 20t+70s = 40*20 gallons
Modify for elimination:
2t + 2s = 2*20
2t + 7s = 4*20
Subtract and solve for "s":
5s = 2*20
s = 8 gallons (amt. of 70% mix needed)
t = 20-8 = 12 gallons (amt of 20% mix needed)

Is 6 a solution to the equation x^2 - 4 = 5x? Please tell me why or why not

TEA [102]

Answer:

6 is not a solution to the given equation.

Step-by-step explanation:

We are given the equation $x^2-4=5x$

We need to know whether or not x=6 is a solution. This means that we should substitute in 6 for each instance of x. Then, if both sides of the equation are equal, then 6 is a solution to the equation.

$x^2-4=5x\\\\(6)^2-4=5(6)\\\\36-4=30\\\\32=30$

As 32 ≠ 30, 6 is not a solution to the given equation.
