12/5=2.4 so 2.40dollars=unit rate 12dollars/5cds=2.40/1cd=unit rate since it cost 2.40 dollars for 1cd, then 2.40 dollars X 9cds=21.60 dollars for 9cds ;)

in a random sample of 32 gas grills, the mean price was $280.90 with a standard deviation of $123.70 (answer)

Are you looking for confidence interval? i will assume so its usually 95 percent C.I which means Z of 1.96 mean + or _(Z) std/square root of the population(n) 280.90 +(1.96)123.70/sq root of 32 280-(1.96)123.70/sq root of 32 sq...

How do you work a problem like for instance 12x6y9 over 3xy6, will you explain this I get confused. (answer)

4x^5 y^3 when you divide powers, you subtract(so x^6-X1)=x^5 y^9/y^6=y^3 and when you multiply powers, you add them

What is the equation of a line that is perpendicular to y=2x+4 and passes through the point (4,6)? (answer)

slope here is 2 but slope of perpendicular line is 1/2 s0 y=mx+b y=6 x=4 m=1/2 y=mx+b so solve for b b=4 soy=1/2x+4 A

how can I graph -10x = 5y ? (answer)

first divide everything by 5 y= -2x now to graph, start at zero then go down two over 1... then repeat ;)

n + (n + 1)=329 2n+1=329 n=164 therefore n+1=165 164+165=329

She would have to drive 55mph 1mph=8miles xmph=440 440=8x x=55mph

x = first even integer x + 2 = second even integer x + x + 2 = 138 2x+2 =138 x=68 x+2=70 68+70=138

how can I graph y=-0.5x + 4 ? (answer)

4 is the y- intercept.... so go up 4 on the y- axis. 0.5 is the slope... u go .5 up and 1 over
