1. a shop has one-pound bags of peanuts for $2 and three-pound bags of peanuts for $5.50. if you buy 5 bags and spend $17, how many of each size bag did you buy? show your work. 2. use a graphing calculator to find a linear model for the set of data. a. write the equation for broccoli. b. write the equation for cucumber. c. in what year will the two quantities be equal? give a reason for your answer. 3.1cr1 3. you can choose between two tennis courts at two university campuses to learn how to play tennis. one campus charges $25 per hour. the other campus charges $20 per hour plus a one-time registration fee of $10. a. write a system of equations to represent the cost c for h hours of court use at each campus. b. use a graphing calculator to find the number of hours for which the costs are the same. give a reason for your answer. c. if you want to practice for a total of 10 hours, which university campus should you choose? why?

1) 3 one pound bags and two three pound bags.

3a) 25h = c & 20h + 10 = c

3c) You would choose the campus that charges 20h + 10 because it would be $40 cheaper.

Step-by-step explanation:

1) 2a + 5.5b = $17

There must be an even number of the 3lb bags because the price is not a whole number but $17 is. There must be at least two 3lb bags because $17 is an odd number that 2 cannot go into evenly. There cannot be more than three 3lb bags because more than that would cost over $17. With these limitations there must be two 3lb bags, which leaves three 1lb bags.

2(3) + 5.5(2) = $17

3a) 25 is the constant and h is the variable. Therefore the equation should be 25h = c

20 is the constant and h is the variable. There is always $10 added for the fee. Therefore, the equation should be 20h + 10 = c

3c) 25(10) = $250

     20(10) + 10 = $210

You would choose the campus that charges 20h + 10 because it would be $40 cheaper.

Sorry I couldn't answer all of them ):

where r the answers

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
