A submarine is 1000 feet below sea level and then rises 450 feet. Where is the submarine now?

Answer:

difference means subtraction operation.

let the number be n :

[tex](5 \times n) - 7 = 53[/tex]

arrange the equation:

[tex]5n - 7 = 53[/tex]

______________________________________

---------------------------♦ end ♦----------------------------------

further more [ getting value of n ]

add 7 on all sides:

[tex](5n - 7) + 7 = 53 + 7 \\ 5n = 60[/tex]

divide all sides by 5:

[tex] \frac{5n}{5} = \frac{60}{5} \\ \\ n = 12[/tex]

Answer:

Ok. so let's teach you how to find the angles of a triangle. When you add all three sides, they must equal 180 degrees. Because of this, let's do some math. What is 96+35. Ima pretend you said 131 and so you would be right. Now let's subtract that from 180 degrees. 180-131 is 49 and so x is 49 degrees. Hope this helps!!

The difference between the freezing point of water and mercury is 70°F.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that mercury has a freezing point of -38°F and water has a freezing point of 32°F.

The difference between the freezing point of water and mercury is calculated below

Difference =  freezing point of water -  freezing point of mercury

Difference =  32 - ( -38)

Difference =  70°F

Therefore, the difference between the freezing point of water and mercury is 70°F.

Answer:V=3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

12v+10v+14=80

(12v+10v)+(14)=80

(Combine Like Terms)

22v+14=80

22v+14=80

Step 2: Subtract 14 from both sides.

22v+14−14=80−14

22v=66

Step 3: Divide both sides by 22.

22v/22=66/22

V=3

Answer:

46.5 hours per week

Step-by-step explanation:

At least 550 a week.

Which is 1\4 of Bronwyn salary.

550 x 4 = 2200

To find minimum work hours

2200-28 = 2172

2172 \ 47 = 46.212 hours per week

So, bronwyn needs to work at least 46.5 hours per week

Answer:

Bronwyn must work nearly 47 hours each week to achieve her goal.

Step-by-step explanation:

Let x be the number of hours Bronwyn works per week.

If Bronwyn earns $47 per hour, if x is the number of hours she works per week and if Bronwyn earns $28 per week because she declined company benefits, lets assume that the left hand side of the equation is:

[tex]47x + 28[/tex]

Now onto the salary. Since Bronwyn wants to save $550 each week and since she also wants to save one quarter of her salary, her salary becomes $2200 for each week she works

Making the equation...

[tex]47x + 28 = 2200[/tex]

Time to solve for x

[tex]47x = -28 + 2200\\47x = 2172\\x = 46.2[/tex]

Since its at least, you can round it up to 47 making 47 the number of hours she must work each week to achieve her goal.

Answer:

8

Step-by-step explanation:

4(x-3) -2(x+1) =2​

=> 4x - 12 - 2x - 2 = 2      [opening brackets]

=> 4x - 2x - 12 - 2 = 2

=> 2x - 14 = 2

=> 2x = 14 + 2

=> 2x = 16

=> x = 16/2

=> x = 8

4 ( x - 3 ) - 2 ( x + 1 ) = 2

2 ( x - 3 ) - ( x + 1 ) = 1

2x - 6 - x -1 = 1

2x - x = 1 + 6 + 1

x = 1 + 6 + 1

x = 7 + 1

x = 8

Distance = (Rate)(Time)

Let x = speed of slower train

     x + 17 = speed of faster train

The trains meet when the sum of the distances = 1285

5x + 5(x+17) = 1285

(5 came from 5 hours)

10x + 85 = 1285

10x = 1200

 x = 120 mph

The speeds are 120 mph and 137 mph
