The formula K = 5/9 (F+ 459.67) gives K, the temperature in Kelvin, in terms of F, the temperature in degrees Fahrenheit. Which equation can be used to calculate the temperature in degrees Fahrenheit, F, in terms of K?

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

i think the answer is true

step-by-step explanation:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
