Find the value of x that will make l and m 7x-7, 4x+14

ohaa [14]

Answer:
x = 7

Explanation:
We are given that:
l = 7x - 7
m = 4x + 14

We want to have:
l = m

Therefore, we will simply equate the two equations and solve for x as follows:
7x - 7 = 4x + 14
7x - 7 - 4x = 4x + 14 - 4x
3x - 7 = 14
3x - 7 + 7 = 14 + 7
3x = 21
x = $\frac{21}{3}$
x = 7

Hope this helps :)

a cell phone company has a basic monthly plan of $40plus $0.45 for many minutes ised over 700. John was charged a total of $48.1

jonny [76]

Cost of month plan = $40

Cost of minutes used = $0.45 after 700 minutes

Total cost = $48.10

Let x be the total minutes used
Total cost = 40 + 0.45(x - 700)

------------------------------------------------------------------
Form the equation and solve x
------------------------------------------------------------------
40 + 0.45(x - 700) = 48.10
40 + 0.45x - 315 = 48.10
0.45x - 275 = 48.10
0.45x = 48.10 + 275
0.45x = 323.10
x = 323.10 ÷ 0.45
x = 718

------------------------------------------------------------------
Answer: John had used 718 mins this month

If the cost of manufacturing mobile phones is $10,000 for the factorytime plus $80 per phone and that each

ozzi

Answer:

500 phones

Step-by-step explanation:

cost of manufacturing: y = 80x + 10,000

money from phone sales: y = 100x

* note: x = #phones

solve for when they're equal;

100x = 80x + 10,000

100x - 80x = 80x - 80x + 10,000

20x = 10,000 –––––––––––> divide both sides by 20

x = 500
