How do you add integers with different signs?

A
Just add their absolute values

B
Subtract their absolute values and keep the sign of the integer with the greater absolute value.

C
Add their absolute values and keep the sign of the integer with the smaller absolute value.

D
Add their absolute values and keep the sign of the even integer.

The weight of a radioactive isotope was 96 grams at the start of an experiment. after one hour, the weight of the isotope was half of its initial weight. after two hours, the weight of the isotope was half of its weight the previous hour. if this pattern continues, which of the following graphs represents the weight of the radioactive isotope over time? a. graph w b. graph x c. graph y d. graph z

The area (a) of a circle with a radius of r is given by the formula and its diameter (d) is given by d=2r. arrange the equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.

Drag each equation to the correct location on the table. for each equation, determine the number of solutions and place on the appropriate field in the table.
