Answer:

-13/4

Step-by-step explanation:

1.) convert to improper fraction.

-39/8 * 2/3

2.) multiply top

-39 * 3 = -117

3.) multiply bottom

8 * 3 = 24

4.) simplify

-117/24 = -13/4

Answer:

12

Step-by-step explanation:

1/2x+2=2/3x

2= 2/3x-1/2x

2=4/6x-3/6x

2=1/6x

multiply both sides by 6

x=12

Answer: x = 12

Step-by-step explanation:

1/2x + 3= 2/3x + 1​

= 1/2x + 3 - 3 = 2/3x +1 -3

Simplify

= 1/2x = 2/3x -2

= -1/6x = -2

multiply both sides by -6

(-1/6x)(-6) = (-2)(-6)

x = 12

Answer: 47.12

Step-by-step explanation: 15 x pi. Or 15 x 3.14159.

Step-by-step explanation:

Let's solve your equation step-by-step.

−5(x+4)=70

Step 1: Simplify both sides of the equation.

−5(x+4)=70

(−5)(x)+(−5)(4)=70(Distribute)

−5x+−20=70

−5x−20=70

Step 2: Add 20 to both sides.

−5x−20+20=70+20

−5x=90

Step 3: Divide both sides by -5.

−5x

−5

=

90

x=−18

Answer:

x=-18

Step-by-step explanation:

-5(x+4)=70

x+4=-14

x=-14-4

x=-18

Answer:

W times H

Step-by-step explanation:

Answer:

Step-by-step explanation:

For Logan:

Logan swam 750m

Logan distance = 750m

Time taken = 1.3×3600

Time taken = 4680

Logan average speed = distance/time

average speed = 750/4680

Logan Average speed = 0.160m/s

Mila swam 2.3 of Logan's distance

Milan distance = 1725m

Time taken = 1.4×3600

Time taken = 5040s

Milan average speed = distance/time

Milan average speed = 1725/5040

Milan average speed = 0.342m/s

Comparing Milan speed with Logan speed:

Difference in speed = 0.342-0.160

Difference in speed = 0.182m/s

This means that Milan speed is 0.182 greater than Logan speed.

Answer:

1,267,200

Step-by-step explanation:

Given that the map reported that the scale is 1 inch to 20 miles.

Recall that there are 63,360 inches in 1 mile, thus, in 20 miles, we have 20 x 63,360 = 1,267,200

Therefore, the scale of 1 inch to 20 miles can also be represented as 1 to 1,267,200

Step-by-step explanation:

Answer: The side length is 3 yards.

Step-by-step explanation:

To find the area of a square, you have to square one of it's side lengths since they all share the same length.  Since we know the area, and we need to find the side length so we just need to find the square root of the area.

[tex]\sqrt{9}[/tex] = 3    

The side length is 3 yards.

The length of each side of a square is, 3 yards.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

⇒ An area of square = 9 yards²

Now, We know that;

⇒ Area of square = Side²

Let the side of square = a

So, We get;

⇒ a² = 9

⇒ a = √ 9

⇒ a = 3 yards

Answer: {10, 13, 16, 19, 22, 25}

Step-by-step explanation:

Cab ride cost for first mile = $10

Additional mile cost = $3

Therefore, the following cab cost for different miles are analysed:

Cab ride cost for first mile = $10

Cab ride cost for second mile = $10 + $3 = $13

Cab ride cost for third mile = $10 + $3 + $3 = $16

Cab ride cost for fourth mile = $10 + $3 + $3 + $3 = $19

Cab ride cost for fifth mile = $10 + $3 + $3 + $3 + $3 = $22

Cab ride cost for sixth mile = $10 + $3 + $3 + $3 + $3 + $3= $25

Therefore, th domain of P(C) will be equal to {10, 13, 16, 19, 22, 25}

Answer:

the answer is -153

Step-by-step explanation:

350-200(she paid off 200$)=150

150+23(she charged her account 23$)=173

173-35(she paid off 35$)=138

138+15(she charged her account 15$)=135

her new balance is -153$ because that is how much she has left to pay off before she reaches 0 then she can gain credit.
