Mariana receives a $20 gift card for downloading music and wants to determine how many songs she can purchase. Each downloaded song costs $1.29. If m represents the number of songs downloaded, which inequality represents the given situation?

20 m greater-than-or-equal-to 1.29

20 m less-than-or-equal-to 1.29

1.29 m less-than-or-equal-to 20

1.29 m greater-than-or-equal-to 20

Which sentence can represent the inequality ?

Two and four tenths times six and two tenths minus a number is larger than negative four and five tenths.

Two and four tenths multiplied by the difference of six and two tenths and a number is more than negative four and five tenths.

The difference of six and two tenths and a number multiplied by two and four tenths is not less than negative four and five tenths.

The product of six and two tenths minus a number and two and four tenths is at minimum negative four and five tenths.

Jessamine wants to ride her bike at least 85 miles per week. She rides to and from school 5 days per week. Her house is 6.25 miles from her school. She rides an additional 2.5 miles for each trip, t, she makes around the park. Which inequality represents the situation?

5 (2) (6.25) + 2.5 t less-than-or-equal-to 85

5 (2) (6.25) + 2.5 t less-than 85

5 (2) (6.25) + 2.5 t greater-than-or-equal-to 85

5 (2) (6.25) + 2.5 t greater-than 85

Each morning Rin rides 1.5 miles to school and then rides home in the afternoon. Later in the evening, she rides to the park and back home. Over the 5 school days, she rides a total of 25 miles. Which equation can be used to find the distance she rides each evening?

1.5 + x = 25

1.5 + 1.5 + x = 25

5 (1.5 + x) = 25

5 (1.5 + 1.5 + x) = 25

Which equation, when solved, results in a different value of x than the other three?

8.3 = negative 0.6 x + 11.3

11.3 = 8.3 + 0.6 x

11.3 minus 0.6 x = 8.3

8.3 minus 0.6 x = 11.3

Which equation can be used to represent the statement?The sum of one-sixth of a number and negative two is equal to negative two-thirds.

One-sixth + n = negative 2 + two-thirds

One-sixth + n = negative 2 + (negative two-thirds)

One-sixth n + 2 = negative two-thirds

One-sixth n minus 2 = negative two-thirds

What is the value of x in the equation ?

–22

–1.1

1.1

What is the solution to ?

x less-than-or-equal-to 3

x less-than-or-equal-to 6

x less-than-or-equal-to 48

x less-than-or-equal-to 96

What inequality is represented by this graph?

x greater-than 6

x less-than-or-equal-to 6

x less-than 6

x greater-than-or-equal-to 6

Which equation can be used to represent the statement?Sixteen is the same as one and two-tenths times a number added to negative 8.

16 + 1.2 n = negative 8

16 + 1.2 n = 8

16 = 1.2 n + (negative 8)

16 = negative 1.2 n + 8
