Last year, Jenna bought 22 ride tickets. This year, Mark and Jenna both bought twice as many ride tickets as they did last year. Together, they purchased 72 tickets this year. How many tickets did Mark purchase last year? Use the variable x to represent the number of tickets Mark purchased last year.

Try 50. Since you can do 72-22=50 tickets for last year.

Step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
