Joshua currently does a total of 8 pushups each day. He plans to increase the number of pushups he does each day by 2 pushups until he is doing a total of 30 pushups each day. How many days would this take? Use x to represent days.

x=12

Step-by-step explanation:

Let y equal number of pushups a day. When x = 1, y = 8. When x = 2, y = 10. 10 is a factor of 30. Multiply y by 3. However, since x increases by 1 when y increases by 2, multiply x by 6 (2*3). That equals 12. Therefore, when x = 12, y = 30.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
