LekaFEV [45]
3.5(c-8)+c = 12.5
⇒ 3.5c- 3.5*8+ c= 12.5 (distributive property)
⇒ (3.5c+ c) -28= 12.5
⇒ 4.5c= 12.5+ 28
⇒ 4.5c= 40.5
⇒ c= 40.5/ 4.5
⇒ c= 9

The correct answer is 9~

A tuition scale for a state university shows an increase of $1,100 each year. If the initial cost was $27,000. What will the cos
oksian1 [2.3K]

If each years cumulate an increase of 1100 dollars, then the cost after 22 years will be the base cost (27000) plus 22 increases (22*1100), for a total of

27000 + 22\cdot 1100 = 27000 + 24200 = 51200

This relates to arithmetic series as follows: a series is arithmetic if, given a starting element x_0, every next element is given by adding a fixed number, called common difference, r. So, the first terms are

  • a_0 = x_0
  • a_1 = x_0 + r
  • a_2 = x_1 + r = (x_0+r) + r = x_0 + 2r
  • a_3 = x_2 + r = (x_0+2r) + r = x_0 + 3r
  • a_4 = x_3 + r = (x_0+3r) + r = x_0 + 4r

So, you can see that the element x_n is obtained by adding n times the common ratio to the starting element.

Since the element a_n represents the cost after n years, we are interested in the element

a_{22} = x_0 + 22r = 27000 + 22\cdot 1100 = 512000

As we had already calculated.

3(2x-3)=24 solve for x
Monica [59]

Answer:

5.5

Step-by-step explanation:

3(2x-3)=24

first, isolate the variable. this means that you get rid of the three outside of the parenthesis

\frac{3(2x-3)=24}{3}

2x-3=8

Now you have the variable and another number. To get rid of 3, do the opposite of subtracting.

2x=11

Divide 11 by 2 and you have 5.5 :)
