Answer:

x = 11.4

Step-by-step explanation:

14.12 = \frac{1}{2} ( 3.6x - 12.8 )

Rewrite so that the equation is entirely in decimals;

14.12 = 0.5( 3.6x - 12.8 )

Distribute;

14.12 = 1.8x - 6.4

Inverse operations;

14.12 = 1.8x - 6.4

+6.4            +6.4

20.52 = 1.8x

/1.8        /1.8

11.4 = x

An elevator is rated to safely hold ten 250 lb people. The elevator is loaded as follows: three 600 lbs cartons of books, Jim (1
iris [78.8K]
To do this, we will need to find how much the elevator can hold in all. Multiply 10 by 250 to get 2500. Since it can also hold 10% more, multiply 2500 and 0.10 to find out how much 10% is. You get 250. Add 2500 and 250 to get how much the elevator can safely hold. It would be 2750.

To find out how much more weight can be added, first find out how much weight is on the elevator collectively. (books) 600+ (Jim) 180+ (Gavin) 330 + (Deb) 250 + (Susan) 120 = 1480. Subtract this from the amount the elevator can hold, and you get how much more weight can be added. 2750-1480= 1270.

The elevator can hold 1270 more ibs.

Pleaseeee i will mark brainlesttttt<br> solve this system of equations <br> 12x−15y=14 8x−15y=6
Sphinxa [80]

Answer:

x = 2 and  y = \frac{2}{3}

Step-by-step explanation:

To solve this system of equation, we will follow the steps below;

We will use both elimination and substitution method to solve this system of equations

12x−15y=14 ------------------------------------------------------------------------(1)

8x−15y=6 --------------------------------------------------------------------------(2)

subtract equation (2) from equation (1)

(By doing that the y  variable will be eliminated)

4x = 8

Divide both-side of the equation by 4

4x/4 = 8/4

x = 2

Substitute x =2 into equation (2) and then solve for y

8x−15y=6

8(2)−15y=6

16 - 15y = 6

subtract 16 from both-side of the equation

16 - 16- 15y = 6-16

-15y = -10

Divide both-side of the equation by -15

-15y/-15  = -10/-15

y = \frac{2}{3}

x = 2 and  y = \frac{2}{3}
