Kira solved the equation in the following way. 7/2 − 2x = 11/2 7/2 − 7/2 − 2x = 11/2 − 7/2 −2x ÷ −2 = 4/2 ÷ − 2 x = −1 Describe the properties of equality that Kira used. The first step is to use the property of equality to combine the constant terms. The second step is to use the ___ property of equality to isolate the variable.

Assume that a population of 50 individuals has the following numbers of genotypes for a gene with two alleles, b and b: bb = 30, bb = 10, and bb = 10. calculate the frequencies of the two alleles in the population’s gene pool.

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126
