Step-by-step explanation:

x=-10 is ur answer try it!

Answer:

2x=-20 or simplified version x=-10

Step-by-step explanation:

-8+3x=12+5x

   -3x.      -3x

-8 = 12+2x

-12=-12+2x

-20=2x

x=-10

Answer:

it's the second choice (3=3)

Answer:

y = - x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 3) and (x₂, y₂ ) = (3, 1)

m = [tex]\frac{1-3}{3-1}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1 , then

y = - x + c ← is the partial equation

To find c substitute (1, 3 ) into the partial equation

3 = - 1 + c ⇒ c = 3 + 1 = 4

y = - x + 4 ← equation of line

Answer:

Step-by-step explanation:

r=d/t

r=miles/hour=mph

r=12

Answer: I THINK it’s d

Step-by-step explanation:

Answer:

Part A: B) 3

Part B: $40

4. -1

7. 5x + 6y

8. Part A: y = 20x

8. Part B: $300

9. e > 12000 pounds

Step-by-step explanation:

Part A: x = 5t + 5

20 = 5t +5

15 = 5t

t = 3

Part B: x = 5t + 5

x = 5(7) + 5

x = 35 +5

x = 40

4. 24 - 5^2

24 - (5*5)

24 - 25 = -1

7. 2x + 4y + 5 + 2y - 5 + 3x

2x + 3x = 5x

4y + 2y = 6y

5 + (-5) = 0

5x + 6y

8. Part A:

Total = y

Lawns = x

Amount = $20

so y = 20x

8. Part B:

y = 20x

y = 20(15)

y = 300

9. The elephant weighs more than 12000 pounds

Elephant = e

More than =  >

Pounds = 12000

e > 12000 pounds

Answer:

12

Step-by-step explanation:

If the perimeter is 58,

take 17(2) for booth sides.

Which you will get 34.

58-34=24

Now you know that the remainder is the two vertical sides.

24/2=12

BC=12

Answer: $234.5

Step-by-step explanation: when you get a 40% off that means you would pay 60% but then you have to play 7% so you have to pay 67% of 350 wich is 234.5

Answer:

$149.8

Step-by-step explanation:

40% of 350 is 140

7% of 140 is 9.8

Answer:

(0, -2)

Step-by-step explanation:

Since line is intersecting y axis at point (0, - 2)

Hence, y-intercept = (0, - 2)

Answer:

Average speed is 3 kilometers an hour

Answer:

£ 5400

Step-by-step explanation:

P = £ 7500

r = 12% = 0.12

t = 6 years

Simple Interest = P*r*t

                         = 7500 * 0.12 * 6

                         = £ 5400

Answer:

Average speed is like .83miles per minute and roughly 50 per hour

Step-by-step explanation:

Using the together rate, it is found that it would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

The together rate is the sum of each separate rate.

In this problem, the rates are:

Hence, applying the equation for the together rate:

[tex]\frac{1}{2} = \frac{1}{x} + \frac{1}{3}[/tex]

[tex]\frac{x + 3}{3x} = \frac{1}{2}[/tex]

[tex]2x + 6 = 3x[/tex]

[tex]x = 6[/tex]

It would take the apprentice 6 hours to make the same number of sets of glasses when working alone.

Step-by-step explanation:

C = 2.32N + 34180

120000 = 2.32N + 34180

85820 = 2.32N

N = 85820/2.32

N = 36991

Answer:

1/30

Step-by-step explanation:

the probability of picking white is 2/16 simplified to 1/8

the probability of picking a green would equal to 4/15

notice that it is not 4/16, because you already picked out one of the colours, and you are not replacing it, so if you take it out, then there is 15 left to pick from.

you would then multiply

1/8 x 4/15

= 4/120

simplified to

1/30
