While scuba diving, Jake dove a depth of 12.6 feet below the surface of the water and then descended another 8.7 feet. What expression can be used to find Jake's new position

the  expression that can be used is -12.6 feet - 8.7 feet

Step-by-step explanation:

The computation of the expression that used for determine the Jake new position is as follows;

Given that

Depth of 12.6 feet below the surface

The another 8.7 feet is descended

Based on the above information,

The expression that can be used is

= (-12.6 feet) + (-8.7 feet)

= -12.6 feet - 8.7 feet

hence, the  expression that can be used is -12.6 feet - 8.7 feet

step-by-step explanation:

mean or average is 40.6

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
