Arnob, Bella, Colin, Dante, and Erin are going to a baseball game. They have a total budget of $100.00 to spend. Each game ticket costs $17.50 and each drink costs $2.00. The inequality below relates x, the number of drinks the 5 friends could buy in all, with their ticket costs and budget.Which best describes the restrictions on the number of drinks they can buy?

They can buy only from 0 to 3 drinks, but no more.

They can buy only from 0 to 6 drinks, but no more.

They can buy only from 0 to 7 drinks, but no more.

They can buy only from 0 to 12 drinks, but no more.

Simplify the expression 3x(–2x + 5).

In order to solve for the variable in the equation , Giovanni first applies the distributive property. Which equation is a result of this step?

8 x + 3 + 4 = 3 x minus 2 x + 4

8 x + 6 + 4 = 3 x minus 2 x minus 4

6 x + 5 + 4 = 3 x minus x + 3

6 x + 3 + 4 = 3 x minus x + 4

In order to solve for the variable in the equation , Jaleesa begins by applying the distributive property, then combines like terms. Which equation is the result of these steps?

7 x + 6 = 6 x minus 3

2 x + 6 + 5 x = 6 x minus 3

2 x + 3 + 5 x = 6 x minus 1

7 x + 3 = 6 x minus 1

Which expression represents the product of and –8x?

Look at the two equations:-3x + 6 = 21-3x + 6 < 21Which statement best describes the process used to solve the equations?

In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.

In both cases, divide by –3 on both sides, but reverse the inequality sign when doing that for the inequality.

The process is exactly the same for solving the equation and solving the inequality.

The process for solving the equation is entirely different from solving the inequality.

Which is the solution to the equation ? Round to the nearest tenth if necessary.

7.6

8.9

What is the solution to ?

x >

x <

x > 2

x < 2

Sarita showed the steps to solving the equation. StepsSarita’s SolutionSarita’s Verification1 23 4 5 When Sarita tried to verify her answer, she found it was wrong. Which explains her mistake?

Sarita’s solution is correct. She made an error in her verification.

Sarita was supposed to add the 5 and 7 in the first step.

Sarita added +13 instead of in the fourth step.

Sarita was supposed to use the division property of equality in the third step.

Misha solves the equation by applying the distributive property to each side of the equation. The result is . Misha then wants to combine like terms. Which are the terms Misha should combine?
