Let x = the first even number
x + 2 the second
x + 4 the third
x + 6 the fourth
Add together.
x + x + 2 + x + 4 + x + 6 = 92
Combine like terms.
4x + 12 = 92
Subtract 12 from both sides
4x = 80
Divide both sides by 4
x = 20
Equation
Because expressions don't contain equal signs
The logical approach would be to look at the totals, as you're trying to get the class favourite. Looking at such values, we see that Spiderman is the most trending, with the higher frequency, making it the class favourite.
Answer:
a
Step-by-step explanation:
Answer:
x=−1 or x=−6
Step-by-step explanation:
Multiply all terms by x and cancel:
xx+6=−7x
x2+6=−7x(Simplify both sides of the equation)
x2+6−−7x=−7x−−7x(Subtract -7x from both sides)
x2+7x+6=0
(x+1)(x+6)=0(Factor left side of equation)
x+1=0 or x+6=0(Set factors equal to 0)
x=−1 or x=−6
Check answers. (Plug them in to make sure they work.)
x=−1(Works in original equation)
x=−6(Works in original equation)
