Yuki888 [10]

Answer:

A = 40/n

Therefore, she gave each friend 40/n ounces of jelly beans.

Step-by-step explanation:

Given;

Total amount of jelly beans To = 3 pounds = 3×16 ounces = 48 ounces

Total amount kept for family Ta = 8 ounces

Total amount given to friends = Ti

Number of friends = n

Amount given to each friend = A

Ti = To - Ta

A = Ti/n = (To-Ta)/n

A = (48 - 8)/n

A = 40/n

Therefore she gave each friend 40/n ounces of jelly beans.

Find the midpoint of the line segment

strojnjashka [21]

Answer:

midpoint (5,4)

Step-by-step explanation:

The midpoint(M) of a segment with endpoints (x₁ , y₁) and ( x₂, y₂) is

where x₁ = 2 and x₂ = 8

y₁ = 0 and y₂ = 8

M = $\frac{x_1 + x_2}{2} ,\frac{y_1 + y_2}{2}$

M = $\frac{2 + 8}{2} ,\frac{0 + 8}{2}$

M = 5 , 4

Flura [38]

Answer:

The x's cancel so definitely is choice C: 1/9

Step-by-step explanation:

We have root( 1/(x^2) ) * root ((x^2) / 81)

simplifying this we get as follows:

root( 1/(x^2) ) * root ((x^2) / 81)

= $\sqrt{(1/x^2 )}$ * $\sqrt{(x^2)/81}$

= ( 1/x ) * (x/9)

the x's cancel

= 1/9

choice C 1/9
