All of the following expressions have the same value except _____.
-16 ÷ 2
(2)(-4)
(-2)(4)
-16 ÷ -2

The correct answer is Point A' is located at (-5, -4).

When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).

Answer:

Step-by-step explanation:

#7- Irrational; The adding of one 8 every time it well, gets to an 8, changes the pattern. For a decimal to be rational, it has to be steady, set from the beginning, and has to keep that pattern the whole time.

#9- C and E;

C. Pi (3.14…) is a continuous number that goes on forever and has no pattern to it, thus making it irrational.

E. Is one of those decimals that just decide to be different and difficult and have no repetition of patterns and goes on forever

#10- Just the square root of 15; Square root of 196 is 14; 5/9 is 0.5repeating… which I beliiieeeeve is rational?; and 7.27repeating have the same ongoing pattern

#11- 26, -3/2, 0, 9;

26 is a whole number; -3/2 would be -1.5 as a decimal, no extra numbers; 0 just… well… 0, so rational; and 9 is a whole number.

#12- No, it is irrational.; Same explanation as number 7, but instead of 8’s and 7’s it’s with 5’s and 6’s.

Answer: 1,600 ml

Step-by-step explanation:

You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).

2,800 ml - 1,200 ml = 1,600 ml

I hope this helps :)

Answer: 1,600 mL

Step-by-step explanation:

1. convert the 1,200 mL to L, which is 1.2 L.

2. Subtract that value from 2.8 L, equaling 1.6 L

3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

Answer:

Option d. (also option e depending on which way you want to calculate it)

Step-by-step explanation:

First, I should point out that percentage basically means 'out of one hundred' so 25% means '25 out of one hundred.' The value of the percentage increase = 25% × 865. The new value = 865 + The value of the percentage increase.

______________________________________

More Simple Explanation:

Alright, so this might not be a super 'mathematical' trick or related to this question but it still works. Basically we just have to convert 25% into a decimal which I do by moving the decimal point 2 numbers to the left. (Since we cannot see the decimal point in the percentage we automatically know that it stays at the end of 25 a.k.a 25.0) So now our number becomes 0.25 (we got rid of the percentage symbol). Now we just multiply 865 by 0.25 to get our answer!

______________________________________

More Mathematical Process *Basically the value and random useless stuff to know lol because my math teacher showed me this and I thought I needed to add this*:

1) Calculate the new value of the number increased by percentage of its initial value

The new value =

865 + The value of the percentage increase =

865 + (25% × 865) =

865 + 25% × 865 =

(1 + 25%) × 865 =

(100% + 25%) × 865 =

125% × 865 =

125 ÷ 100 × 865 =

125 × 865 ÷ 100 =

108,125 ÷ 100 =

1,081.25

2) Calculate the actual change (the difference) between the new value and the initial one

The actual change =

The new value - 865 =

1,081.25 - 865 =

216.25

(For positive numbers, the actual change = The value of the percentage increase)

Answer:  15 for the first part

(5/2)² < 12.06 but

If  y is supposed to be a factor,  like multiply by 2, then

(5/2)²y > 12.06

Step-by-step explanation:  substitute 2 for y

20y - 5² = 2

20(2) -  25 =

40 - 25 = 15

__________

(5/2)² = 5²/2²

25/4 = 6.25 . So that is less than 12.06

But if  y is supposed to be a factor,  like multiply by 2, then

(5/2)²y > 12.06

Answer:

0.14 $

Step-by-step explanation:

Price of 20 ounce bottle of mustard for $2.80.

Price of 1 ounce bottle of mustard for 2.80÷20 $

                                                             = 0.14 $

Answer:

let t = no of minutes when they are at the same altitude

:

52200 - 3300t = 2500t

52200 = 3300t + 2500t

52200 = 5800t

t = 52200/5800

t = 9 minutes they will be at the same altitude

:

The altitude:

9*2500 = 22500 ft

:

Check on other train

52200 - 9(3300) =

52200 - 29700 = 22500 ft

Answer:

Here are your answers!

Step-by-step explanation:

x/5+5=6 is x=5.

18-2x=9 is NOT x=5, it is x=9/2

32-4x=12 is x=5.

11+6x=22 is NOT x=5, it is x - 11/6

3x+1=9 is NOT x=5, it is x = 8/3

25/x+4=9 is x=5.

Brainliest please!

Answer:

\(\boxed{\bigstar \:\:\sf \cfrac{x}{5}+5=6}\)

\(\boxed{\bigstar\:\:\sf 32-4x=12}\)

\(\boxed{\bigstar\:\:\sf \cfrac{25}{x}+4=9}\)

_______________

\(\sf \cfrac{x}{5}+5=6\)

Subtract 5 from both sides:

\(\sf \cfrac{x}{5}+5-5=6-5\)

\(\sf \cfrac{x}{5}=1\)

Multiply both sides by 5:

\(\sf \cfrac{5x}{5}=1\times \:5\)

\(\boxed{\bold{x=5\: \:\checkmark }}\)

~~~~~~~~~~~~~~~

\(\sf 18-2x=9\)

Subtract 18 from both sides:

\(\sf 18-2x-18=9-18\)

\(\sf -2x=-9\)

Divide both sides by -2:

\(\sf \cfrac{-2x}{-2}=\cfrac{-9}{-2}\)

\(\boxed{\bold{ x=\cfrac{9}{2}}}\)

~~~~~~~~~~~~~~~

\(\sf 32-4x=12\)

Subtract 32 from both sides:

\(\sf 32-4x-32=12-32\)

\(\sf -4x=-20\)

Divide both sides by -4:

\(\sf \cfrac{-4x}{-4}=\cfrac{-20}{-4}\)

\(\boxed{\bold{x=5\:\: \checkmark }}\)

~~~~~~~~~~~~~~~

\(\sf 11 + 6x = 22\)

Subtract 11 from both sides :

\(\sf 11+6x-11=22-11\)

\(\sf 6x=11\)

Divide both sides by 6:

\(\sf \cfrac{6x}{6}=\cfrac{11}{6}\)

\(\boxed{\bold{x=\frac{11}{6}}}\)

~~~~~~~~~~~~~~~

\(\sf 3x + 1 = 9\)

Subtract 1 from both sides :

\(\sf 3x+1-1=9-1\)

\(\sf 3x=8\)

Divide both sides by 3:

\(\sf \cfrac{3x}{3}=\cfrac{8}{3}\)

\(\boxed{\bold{x=\frac{8}{3}}}\)

~~~~~~~~~~~~~~~

\(\sf \cfrac{25}{x}+4=9\)

Subtract 4 from both sides:

\(\sf \cfrac{25}{x}+4-4=9-4\)

\(\sf \cfrac{25}{x}=5\)

Multiply both sides by x:

\(\sf 25=5x\)

Let's Switch sides:

\(\sf 5x=25\)

Divide both sides by 5:

\(\sf \cfrac{5x}{5}=\cfrac{25}{5}\)

\(\boxed{\bold{ x=5\:\: \checkmark }}\)
