The sum of 4, five times a number, - 9, and four times a number

Answers:

Vertical distance traveled = 410.7 feet

Mean hourly vertical distance = 136.9 feet per hour

=============================================================

Explanation:

We'll subtract the positive versions of the two numbers (large - small) to get

725.6 - 314.9 = 410.7

This tells us that the distance between those depth markers is 410.7 feet

In other words, the submarine has risen 410.7 feet in vertical distance over those 3 hours.

The mean hourly distance, aka the speed, is

speed = distance/time

speed = (410.7 feet)/(3 hours)

speed = (410.7/3) feet per hour

speed = 136.9 feet per hour

This is another way of saying "each hour, the submarine goes up by exactly 136.9 feet".

Answer:

x= -4

Step-by-step explanation:

−2(4x+4)−3x−2=34

(−2)(4x)+(−2)(4)+−3x+−2=34(Distribute)

−8x+−8+−3x+−2=34

(−8x+−3x)+(−8+−2)=34(Combine Like Terms)

−11x+−10=34

−11x−10=34

−11x−10+10=34+10

−11x=44

−11x /−11  =  44 /−11

Answer:

40

Step-by-step explanation:

Using PEMDAS, we get:

[48 - (19 + 3) ÷ 11] - [36 ÷ (9 - 3)] =

[48 - 22 ÷ 11] - [36 ÷ 6] =

[48 - 2] - [36 ÷ 6] =

46 - 6 =

Hi! I'm happy to help!

When Jenna bought the milk, it deducted (subtracted) $3.58 from her $20. So, let's subtract that here:

20.00

- 3.58

We have to borrow:

19.9(10)

- 3.58

10-8=2

19.9(10)

- 3.58

    .  2

9-5=4

19.9(10)

- 3.58

    .42

9-3=6

19.9(10)

- 3.58

    6.42

and 1-0=1

19.9(10)

- 3.58

$16.42

So, Jenna would receive $16.42 in change for her $20 bill.

I hope this was helpful, keep learning!

The simplified fraction of the subtraction -1 3/5 - (-2 7/8) is 51/40.

To subtract -1 3/5 from -2 7/8, we first need to find a common denominator for the fractions.

The common denominator for 5 and 8 is 40.

Converting the mixed numbers to improper fractions:

-1 3/5 = -8/5

-2 7/8 = -23/8

Now,

-8/5 - (-23/8)

To simplify,

-8/5 + 23/8

Now, we can rewrite the fractions with the common denominator:

(-8/5) × (8/8) + (23/8) × (5/5)

Simplifying:

-64/40 + 115/40  = 51/40

Therefore, the simplified fraction of -1 3/5 - (-2 7/8) is 51/40.

Answer:

AB = 8

Step-by-step explanation:

Given B is the midpoint of AC , then

AB = AC , that is

7x - 6 = 12 - 2x ( add 2x to both sides )

9x - 6 = 12 ( add 6 to both sides )

9x = 18 ( divide both sides by 9 )

x = 2

Then

AB = 7x - 6 = 7(2) - 6 = 14 - 6 = 8
