please show work

Answers

ANSWER:

M = 5

Step 1: Add 1 to both sides of the equal sign

-6m-1+1=31+1

-6m=-30

Step 2: Divide both sides by -6

-6m/6 = -30/-6

(Note: Both -6 values (The denominators) will cancel each other out, which is why the end result is 5 so, again, M=5)

Answer:

Step-by-step explanation:

They will rest after they hike `2` miles. Then they will hike the remaining `1.75` miles to the lookout. The trail the hikers will use to return from the lookout is `0.5` miles shorter than the trail they will use to go to the lookout. Each hiker will bring `0.25` gallons of water for each mile to and from the lookout. What is the total amount of water each hiker will need to carry?

Answers

Answer:

1.75 gallons

Step-by-step explanation:

First, we need to calculate how far the hike is going up the trail. They first hike 2 miles and then another 1.75 miles after resting so...

2 + 1.75 = 3.75 miles

The trail is 3.75 miles long, the question states that the return path is 0.5 miles shorter, therefore...

3.75 - 0.5 = 3.25 miles

Leaving us with a total hiking distance of

3.75 + 3.25 = 7 miles.

Since each hiker will carry 0.25 gallons for each mile we simply need to multiply this amount by the total number of miles in the hike.

7 * 0.25 = 1.75 gallons

Finally, we can see that each hiker will carry a total of 1.75 gallons of water for the entire hike.

Las dimensiones de un prisma rectangular son x + 5 para la longitud, x + 9 para el ancho yx para la altura. ¿Cuál es el volumen del prisma? Ingrese su respuesta como un polinomio en forma estándar.

Answers

Answer:

Step-by-step explanation:

The total area of ​​the prism: A = 2 [3h² + 21h + 24]

The volume of the prism: V = h³ + 11h² + 24h

The area of ​​a rectangular prism is calculated by knowing the sides of the rectangular base (a and b) and its height (h)

A = 2 (ab + ah + bh)

The volume of a rectangular prism is calculated as the product of its dimensions:

V = a * b * h

b- a = 5 ⇒b = 5 + a

what is the quotient of 6 1/4 ÷ (-5/8)​

Answers

Answer: -10

Step-by-step explanation:

1. Convert 6 1/4 to an improper fraction

25/4

2. Find the quotient using the keep, change, flip method

- Keep the first fraction (25/4)

- Change the division sign to a multiplication sign

- Flip the second fraction (i.e. find the reciprocal)

-5/8 -> -8/5

3. Multiply and solve by multiplying the numerators and denominators together respectively

25/4 * -8/5

25*-8 = -200

4*5 = 20

-200/20 = -10

What is the equation of the line that passes through the point (4,−7) and has a slope of -1/2?

Answers

Step-by-step explanation:

y = -0.5x + c

When x = 4, y = -7.

=> (-7) = -0.5(4) + c, c = -5.

Therefore the equation is y = -0.5x - 5.

Answer:

y = -1/2 x - 5

Step-by-step explanation:

y = mx + b

m = slope = -1/2

y = -1/2 x + b

-7 = -1/2 * 4 + b

-7 = -2 + b

b = -5

y = -1/2 x - 5

D. The checking account is overdrawn by $15.

Step-by-step explanation:

Since the balance on a checking account represents the remaining money left in that checking account, having a negative value for that would mean an overdrawing of money, or drawing more money than is in that account in the first place.

Therefore, the answer would be that the checking account is overdrawn by $15.

Brad had a small gathering at a local steakhouse. The steakhouse offers three dinner platters which vary by size and price. They ordered 4 of the 6-ounce platters, 2 of the 8-ounce platters, and 2 of the 11-ounce platters.

Steak Platter Prices
• 6-ounce $9.95
• 8-ounce $12.95
• 11-ounce $15.95

If a gratuity of 18% was added to the bill, which of the following is closest to the total of the steak platters and gratuity, ignoring sales tax?
A.
$114
B.
$137
C.
$18
D.
$115

Answers

Answer:

D.) $115

Step-by-step explanation:

9.95 x 4 = 39.8

12.95 x 2 = 25.9

15.95 x 2 = 31.9

39.8 + 25.9 + 31.9 = 97.6

97.6 x 0.18 = 17.568

97.6 + 17.568 = 115.168

115.168 ≈ 115

9.95 x 4 = 39.8

12.95 x 2 = 25.9

15.95 x 2 = 31.9

39.8 + 25.9 + 31.9 = 97.6

97.6 x 0.18 = 17.568

97.6 + 17.568 = 115.168

115.168 ≈ 115

Therefore, the closest to the total of the steak platters and gratuity, ignoring sales tax is $115.
