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!

Answer:

Step-by-step explanation:

11 + (-7)

= 11 - 7

= 4

(x + 16)/3 = 3x / · 3

x + 16 = 9x

x - 9x = 16

-8x = 16 / : (-8)

x = -2 ← the end

Answer:

D. x = 2 (last/fourth option)

Step-by-step explanation:

[tex] \frac{x + 16}{3} = 3x[/tex]

[tex]x + 16 = 9x[/tex]

[tex]x - 9x = - 16[/tex]

[tex] - 8x = - 16[/tex]

Hey there!

A function is like a machine. You put numbers in it and it gives you one number. You can end up with the same output, but you cannot put in the same number multiple times and get different results. It gives you the same number if you do the same one. Functions cannot have multiple outputs for the same input.

We see here that this relation is not a function. So, we can repeat 2, 8, or 3 to get the corresponding y-value and also 0. For example, a could be 2 and it has 2 outputs which would be -5 and 0. This makes it not a function, so our possible values will be 2, 8, and 3.

Have a wonderful day and keep on learning! :D

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

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:

B. 21

Step-by-step explanation:

3x7= 21 they both have this multiple in common

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.
