What is the value of 4/15 divided by 2/3? A. 8/45 B. 14/15 C. 5/2 D. 2/5
X-2x-15??????
HELP!!!
Answer:
-x-15
Step-by-step explanation:
x-2x-15
1x-2x-15 (if a term doesn't have a coefficient then the coefficient is 1)
(1-2)x-15 (collect like terms by subtracting their coefficients)
-1x-15
-x-15 (when the term has a coefficient of -1, the number doesn't have to be written but the sign remains)
Solve the two following simultaneous equations and find the possible values of x and y. [tex]x^2 +y^2-2xy = 64[/tex]
[tex]x^2 - y^2 = 40[/tex]
Step-by-step explanation:
If u assume x=y=1, then x+y=2 and x^2+y^2=2
And now, xy=1.
Therefore x=y=1.
Let me know, if anyone come with other answers too.

Step-by-step explanation:
(*) x^2 + y^2 - 2xy = 64
<=> (x - y)^2 = 64
<=> x - y = 8 or x - y = -8
(**) x^2 - y^2 = 40
<=> (x - y)(x + y) = 40
Case 1: x - y = 8
(**) <=> 8(x + y) = 40
<=> x + y = 5
we have: x+y = 5 and x-y = 8
--> x = (5+8)/2 = 6.5
--> y = x - 8 = 6.5 - 8 = -1.5
so (x,y) = (6.5 , -1.5)
Case 2: x - y = -8
(**) <=> -8(x + y) = 40
<=> x + y = -5
we have: x + y = -5 and x - y = -8
--> x = [ (-5) + (-8) ]/2 = -6.5
--> y = -5 - x = -5 + 6.5 = 1.5
so (x,y) = (-6.5 , 1.5)
Answer: (x,y) = (6.5 , -1.5) and (-6.5 , 1.5)

Actually Welcome to the Concept of the Logical Analysis of pattern.
Since here we can determine it,
It shows that,
8-4 = 4 +6 = 10 and so, on
so,
3rd option is the answer.
--> Subtract 4 , Add 6 , repeat it
Answer:
From 8 to 4, there is a difference of 4, and from 4 to 10 a difference of 6. This continues until 8, and the next in the pattern if plus 6.

If the following angle pairs are supplementary then what is the measure of the missing angle?
Answer:
c
Step-by-step explanation:
How to remember which is which? Well, alphabetically they are:
Complementary add to 90°
Supplementary add to 180°
You can also think:
"C" of Complementary is for "Corner" right angle(a Right Angle), and
"S" of Supplementary is for "Straight" (180° is a straight line)
Or you can think:
when you are right you get a compliment (sounds like complement)
"supplement" (like a vitamin supplement) is something extra, so is bigger

my bad i put the wrong answer sometimes i put the wrong answer and i dont pay attention to it at all
i need help ASAP this question is on a school assignment
Answer:
a)12
b)1/12
c)4/12
Step-by-step explanation:
a) the coin is a 1/2 and the dice is 1/6 so you times the bottom number and you get 12
b) since that is a exact one way to get it has to be 1/12 chance
c) so to only get a tails it would be 6/12 and less than 5 means you can get 1,2,3, and 4 so that is 4 ways out of 12 ways so its 4/12

An outdoor spigot at the school has a leak and is dripping water. A student counted eighty drops of water in five minutes and noticed that sixty drops of water filled a container to a level of ten milliliters. If the spigot is not fixed and this dripping rate continues, how many liters of water will be wasted in four weeks? Round the answer to the nearest liter.
Answer:
108 liters
Step-by-step explanation:
Given that:
80 drops are there in 5 minutes.
Time to be considered is 4 weeks.
Let us find number drops in 4 weeks.
Number of drops in 5 minutes = 80
Number of drops in 1 minute = [tex]\frac{80}{5}[/tex]
Number of drops in 60 minutes = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex]
Number of drops in 24 hours (60 [tex]\times[/tex] 24 minutes) = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex] [tex]\times 24[/tex]
Number of drops in 28 days (28 [tex]\times[/tex]24 hours OR 60 [tex]\times[/tex] 24 [tex]\times[/tex]28 minutes) = [tex]\frac{80}{5}[/tex] [tex]\times 60[/tex] [tex]\times 24[/tex][tex]\times[/tex]28 = 645120
Now, we are given that 60 drops = 10 mL
1 drop = [tex]\frac{10}{60}[/tex] mL
645120 drops = [tex]\frac{10}{60} \times 645120[/tex] = 107520 mL
We know that 1000 mL = 1 Liter
1 mL = [tex]\frac{1}{1000}[/tex] Liter
107520 mL = [tex]\frac{1}{1000} \times 107520\ L \approx 108\ L[/tex]
So, the answer is 108 Liter.

Sam works at a used car dealership, where he earns 7% commission on each sale. If he sells a car for $12,000 and another for $17,500, how much commission does Sam earn?
Answer:
$2,065
Step-by-step explanation:
The computation of the commission earned by Sam is shown below:
For each sale, he gets 7% commission
So,
For $12,000, the commission amount is
= $12,000 × 0.07
= $840
And, for another sale i.e. $17,500, the commission amount is
= $17,500 × 0.07
= $1,225
So, the total commission he earned is
= $840 + $1,225
= $2,065
What is the absolute value of 6 added to the absolute value of 5?
Answer:
11
Step-by-step explanation:
I’m pretty sure. Just add it
Answer:
11
Step-by-step explanation:
Absolute value only applies to negative numbers. It will make negative numbers positive. As you can see in the problem, they are asking for the absolute value of positive numbers, so you can ignore the absolute value signs and add normally.

Se distribuyen 400 bolsas en tres urnas sabiendo que la primera tiene 80 menos que la segunda y esta tiene 60 menos que la tercera, averigua cuántas bolsas tiene cada una.
Answer:
Primeras urnas = 60 bolsas
Segundas urnas = 140 bolsas
Terceras urnas = 200 bolsas
Step-by-step explanation:
Deje que las urnas se representen de la siguiente manera
Primeras urnas = a
Segundas urnas = b
Terceras urnas = c
Se nos dice en la pregunta
400 bolsas se distribuyen en tres urnas
Por lo tanto,
a + b + c = 400 bolsas ......... Ecuación 1
Por la pregunta sabemos que
1) El primero tiene 80 menos que el segundo
a = b - 80
2) Y este segundo tiene 60 menos que el tercero
b = c - 60
Por tanto, c = b + 60
Por lo tanto, sustituimos b - 80 por ayb + 60 por c en la Ecuación 1
a + b + c = 400 bolsas ......... Ecuación 1
b - 80 + b + b + 60 = 400 bolsas
Recopilar términos similares
b + b + b - 80 + 60 = 400 bolsas
3b = 400 + 80 - 60
3b = 420
b = 420/3
b = 140 bolsas
Por lo tanto, el número de bolsas en la segunda urna = 140 bolsas
Dado que a = b - 80
a = 140 bolsas - 80
a = 60 bolsas
Por lo tanto, el número de bolsas en la primera urna = 60 bolsas
Dado que c = b + 60
b = 140 bolsas
c = 140 + 60
c = 200 bolsas.
El número de bolsas en las terceras urnas = 200 bolsas.

I am pretty sure the correct answer is D since 2 can be multiplied by 3 to get 6, and 3 can be multiplied by 3 to get 9. Thus, if the number of guitars is multiplied by 3, the number of amps will always be a multiple of 3.
11 Select the decimal that is equivalent to 36 Choose 1 answers 0.28 0.23 0.37 0.37 None of the above
None of those are near 36 at all, so none of the above would be your answer.

Answer:
A) 3<x<13
Step-by-step explanation:
It would be A) 3<x<13. It can’t be D because if it were equal to 3 or 13, it would be a line, not a triangle. X must be greater than 3 and less than 13.
