Riley buys a swim pass for the pool in January. The first month costs $30. Each month after that, the cost is $20 per month. Write the equation for finding the total cost of
a one-year swim pass.

you pay 240 dollars a year

Step-by-step explanation:

y=20x

x is 12

20*12=

240

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
