Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

6x+78=180

Step 1: Subtract 78 from both sides.

6x+78−78=180−78

6x=102

Step 2: Divide both sides by 6

6x/6=102/6

x=17

Answer:

x = 17

Step-by-step explanation:

If you subsitute x in "2x" you get 34. If you subsitute x for "4x - 4" you get 64.

After subtracting 180 from 98 you get 82. Add up 34, 64, and 82 then you get 180.

Ella and kate play basketball last year ella scored 16 points per game kates total points for the season were 22 less than Ellis

KatRina [158]

Alright, lets get started.

Ella and kate played basketball last year.

In each game, Ella scored 16 points.

We have not given the number of games played.

So, lets suppose there are n games played last year.

So, total points of Ella will be = number of games * each game score

total points of Ella will be = n * 16 = 16 n

Kates total points for the season are 22 less than Elli's points

Means , Kates total points = 16 n - 22

This expression is similar with expression given 16 z - 22 (which is give in question)

It means z = n , means variable z means total games played in last year. : Answer

Hope it will help :)

A growth medium is inoculated with 1,000 bacteria, which grow at a rate of 15% each day. What is the population of the culture 6

Leto [7]

<h2>Number of bacteria after 6 days is 2313</h2>

Step-by-step explanation:

Population after n days is given by

$P_n=P_0(1+r)^n$

Initial population, P₀ = 1000

Increase rate, r = 15 % = 0.15

Number of days, n = 6

Substituting

$P_n=P_0(1+r)^n\\\\P_6=1000(1+0.15)^6\\\\P_6=1000(1.15)^6\\\\P_6=1000\times 2.313\\\\P_6=2313$

Number of bacteria after 6 days = 2313
