Tori is saving up for a new drum for her drum set. the drum costs $235. she started with $115. she made $24.50 more mowing her grandmother's yard. which equation could be used to find the amount of money, n, tori still needs to save in order to buy the new drum? n - 115 + 24.50 = 235 115 + 24.50 + n = 235 235 + 24.50 + 115 = n 235 - 115 + 24.50 = n

Segment xz is bisected by point y. if xy = 12x, and the measure of xz = 18x – 6, solve for x

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
