Answer:

$x$

Step-by-step explanation:

$-3x-5-2x>-25$

Subtract the x terms:

$-5x-5>-25$

Add 5 to both sides:

$-5x-5+5>-25+5$

$-5x>-20$

Multiply both sides by -1 and flip the inequality symbol:

$5x$

Divide both sides by 5:

$\frac{5x}{5}$

$x$

Answer:

Option 1

Step-by-step explanation:

Step 1: Write inequality

-3x - 5 - 2x > -25

Step 2: Solve for x

Combine like terms: -5x - 5 > -25
Add 5 to both sides: -5x > -20
Divide both sides by -5: x < 4

Your water bill consists of five parts: A base hookup fee of $32.50, a water fee of $0.03 per gallon of water, a sewer fee of $0

Taya2010 [7]

You have to keep calm and to treat data as it come.

1 ) Start by constant fees :

hook up fees is 32.50 and trash collection fees are 35

so contant fees : 32.50 +35 = 67.50

2 ) Now we have to deal with variable fees which depend on how much water is used

water fees :

0.03 per gallon, and we have 4 000 gallon, so :

0.03*4 000 = 120

Sewer fees :

0.01 per gallon, and we have 4 000 gallon, so :

0.01 * 4000 = 40

3 ) Total before taxation we have :

67.50 +120 +40 = 227.5

4) Now we apply tax on the total before tax.

tax is 5 % , which mean you rise the "off tax " price by 5 percent.

To grow a number of X % , you multiply by 1+ X/ 100

here X = 5 so the multiplicator is : 1 + 5/100 = 1.05

So total of the bill is : 227.5 * 1.05 = 238.875

The water compagny is probably going to round it up to 238.88

Answer:

Step-by-step explanation:

8). $\left \{ {{4x+3y=1} \atop {x+y=2}} \right.$

(2) × [ - 3 ]

4x + 3y = 1 ........ (3)

- 3x - 3y = - 6 .... (4)

(3) + (4)

x = - 5

- 5 + y = 2 ⇒ y = 7

( - 5 , 7 )

9). $\left \{ {{-9x+3y=18} \atop {2x+y=-4}} \right.$

(1) ÷ [- 3]

3x - y = - 6 ......... (3)

2x + y = - 4 ........ (4)

(3) + (4)

5x = - 10 ⇒ x = - 2

2(- 2) + y = - 4 ⇒ y = 0

(- 2, 0)

10). $\left \{ {{x-2y=14} \atop {10x-6y=0}} \right.$

(2) ÷ 10

x - 0.6y = 0 ⇒ x = 0.6y -----> (1)

0.6y - 2y = 14

- 1.4y = 14

y = - 10

x - 2(- 10) = 14 ⇒ x = - 6

(- 6, - 10)

Now is your turn, you can do it!!
