<span>The answer is c. 1.5r + 2.5(5 – r) = 10.50. Let r be the number of raisins and p be the number of peanuts. Raisins cost $1.50 per pound: 1.5r. Peanuts cost $2.50 per pound: 2.5p. Jeremy spends $10.50: 1.50r + 2.50p = 10.50. Jeremy makes 5 pounds of trail mix: r + p = 5. So, we have the system of two equations: 1.5r + 2.5p = 10.50 and r + p = 5. Use the second equation to express p: p = 5 - r. Now, substitute p in the first equation: 1.5r + 2.5(5 - r) = 10.50. Therefore, the correct choice is c. 1.5r + 2.5(5 – r) = 10.50.</span>
12% of $79.68 is $9.56
79.68 - 9.56 = 70.07
7.25% of 70.07 = 5.08
70.07 + 5.08 = 75.15

Answer:
26 units
Step-by-step explanation:
p= 10
b= 24
h=?
so according to pythagoras theorem,
h^2= p^2+ b^2
or, h^2= 10^2+24^2
or, h^2= 100+ 576
or, h= 26
Answer:
1,020seconds
Step-by-step explanation:
If Kristen gets home by 5:34pm and dinner is ready by 5:51pm, dorat we need to know interval of time between when when Kristen got home and the dinner time. Since the difference is within minutes, the distance will be the difference between the minutes hand .e 51-34 which is 17minutes.
To get the amount of seconds within this period, we will have to convert 17mimutes to seconds.
1minutes = 60seconds
17minutes = x seconds
Cross multiplying
x = 17×60
x = 1020seconds
