Hi there!

The Eqn. is :-

1.5 (x + 4) - 3 = 4.5 (x - 2)

1.5x + 6 - 3 = 4.5x - 9

Combining the like terms :-

1.5x - 4.5x = - 9 - 6 + 3

- 3x = - 15 + 3

- 3x = - 12

x = \dfrac {- 12}{- 3}

x = 4

Hence, the required answer is → x = 4

~ Hope it helps!

Hi there! The answer is x = 4.

Let's solve this equation step by step!
1.5(x + 4) - 3 = 4.5(x  - 2)

First we need to work out the parenthesis, which can for instance be done using rainbow technique.
1.5x + 6 - 3 = 4.5x - 9

First collect terms.
1.5x + 3 = 4.5x - 9

Subtract 3 from both sides
1.5x  = 4.5x - 12

Subtract 4.5x from both sides.
- 3x =  - 12

And finally divide both sides by -3.
x =  \frac{ - 12}{ - 3}  = 4

Each day 1/2 of the money that is in bank value is removed. No money is added to the value. Which of the following represent the
Alchen [17]

Answer:

Option C. exponential decay function

Step-by-step explanation:

In this problem we have a exponential function of the form

y=a(b^x)

where

y ---> is the money that is in the bank

x ----> number of days

a ---> is the initial value or y-intercept

b is the base of the exponential function

r ---> is the rate of change

b=(1+r)

In this problem we have that

Each day 1/2 of the money that is in bank value is removed

so

r=-50\%=-50/100=-0.50 ---> is negative because is a decreasing function

The value of b is equal to

b=1-r=1-0.50=0.50

y=a(0.50^x)

The value of b is less than 1

b<1

That means -----> Is a exponential  decay function

What is x equal to ? Link down below.
scZoUnD [109]

Answer:

50

Step-by-step explanation:

Because of supplementary angles that line has to equal to 180

180-75 = 105

so 105 = (2x + 5)

you can subtract 5 from each side and get

100 = (2x)

then divide each side by 2 and you get

x = 50

you can check it by doing (2 x 50 + 5)

2 x 50 = 100 + 5 = 105 + 75 = 180
