At the state fair, admission at the gate is $9. In addition, the cost of each ride is $4. Suppose that Heather will go on rides. Heather wants the total number of dollars she spends on admission and rides to be fewer than . Using the values and variables given, write an inequality describing this.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
