On a number line, point s has coordinate 4.8 and point t has coordinate –2.3. which expressions represent the distance between point s and point t? choose all answers that are correct. a. |4.8 +(-2.3)| b. |2.3 - 4.8 | c. | 2.3 - 4.8 | d. | 4.8 _ ( -2.3) |

The only answer that would work would be D) | 4.8 - ( -2.3) |

Step-by-step explanation:

This is because the distance is the absolute value of the difference of the two numbers. B and C would also work, but the 2.3 is not negative. A does not work because it is addition.

x = 12

y = 15

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
