Answer:

13.3

Step-by-step explanation:

Because in order to get the a separated from the 0.9, you must divide the 0.9a by 0.9 to cancel the 0.9 out of the equation. That way, you are left with A. but in order to do that, you must divide both sides of the equation.

Ultimately, it ends up being 12 divided by 0.9, which is 13.3

A phone company offers two monthly plans. Plan A costs S8 plus an additional $0.15 for each minute of calls. Plan B costs $17 pl

SashulF [63]

Answer:

Minutes = 225

Cost = $41.75

Step-by-step explanation:

It is given that:

Cost of Plan A = $8

Per minute cost = $0.15

Let,

m be the number of minutes

A(m) = 0.15m + 8

Cost of Plan B = $17

Per minute cost = $0.11

B(m) = 0.11m + 17

For same cost,

A(m) = B(m)

0.15m+8 = 0.11m + 17

0.15m - 0.11m = 17 - 8

0.04m = 9

Dividing both sides by 0.04

$\frac{0.04m}{0.04}=\frac{9}{0.04}\\m = 225$

Cost of 225 minutes

A(225) = 0.15(225) + 8

A(225) = $41.75

Therefore,

Minutes = 225

Cost = $41.75

Find the midpoint of segment JT when the coordinates are J(-3,18) and T(7,-10). Show all work

nignag [31]

Given two points (x₁,y₁) and (x₂,y₂), the midpoint of the segment will be:
( (x₁+x₂) / 2 , (y₁+y₂)/2 ).
In this case:
J(-3,18)
T(7,-10)

The midpoint will be:
( (-3+7)/2 , (18-10)/2 )=(4/2 , 8/2)=(2, 4).

Answer: the midpoint of segment JT is (2,4)
