Answer:

Step-by-step explanation:

First what you want to is subtract 7 from both sides, then you want to divide -2/3 from both sides.

To isolate the variable you need to remove the terms from the side with the variable to remove the terms you need to do the same thing on both sides.

-2/3n + 7 = 15

First step is to subtract 7 from both sides to get:

-2/3n = 8

Now divide both sides by -2/3 to get:

N = 8 / -2/3

Then to solve for n simplify to get:

N = -12

On the average, a certain light bulb is supposed to last 450 hours. If it
Dafna1 [17]

Answer:

72 novels

Step-by-step explanation:

A number of assumptions are involved regarding operating environment, utilization fraction, and probability of failure as a function of time. The precise meanings of the words "average", "supposed to last", "maximum", and "expect" are involved. The details are too arcane to go into here.

 (450 hours)/(6 1/4 hours/novel)

 = (450/(25/4)) novels

 = (450*4/25) novels

 = 72 novels

3. At the start of summer, Ben has $250 . He takes a summer
earnstyle [38]

Answer:

Week 4

Step-by-step explanation:

Ben has $250 in the beginning.  He saves $150 per week.

y = 150x + 250

Tim has $1,650 in the beginning.  He spends $200 per week.

y = 1650 - 200x

We are trying to find which x-value produces the same y-value for both equations.  You can do this by setting both equations equal to each other.

150x + 250 = 1650 - 200x

(150x + 250) + 200x = (1650 - 200x) + 200x

350x + 250 = 1650

(350x + 250) - 250 = (1650) - 250

350x = 1400

(350x)/350 = (1400)/350

x = 4

By week 4, they will have the same amount of money.
