Answer:
3n - 10
Step-by-step explanation:
Find the difference between the terms
-7 , -4 , -1, 2, 5
+3 +3 +3 +3
Difference of terms = 3, so you'd write that as 3n
Then you'd need to find the difference between the 1st term and 3:
3 > -7
- 10
So you'd write that as 3n - 10

Jessica estimated that her family used 30% more water this month compared to last month . they used 12000 gallons of water last month , how much water did they use this month
Answer:
15,600 Gallons
Step-by-step explanation:
The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
As per the given,
Last used of water = 12000
30% of 12000 = (30/100)12000 = 3600
Water used in the current year = 12000 + 3600 = 15600 gallons.
Hence "The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water".

slove the equation below for y :
6x-4y=12
Answer:
[tex]y=-\frac{3(x +2)}{2}[/tex]
Step-by-step explanation:
We have an equation, and the question is asking for us to solve y. So to solve, we have to isolate y.
6x - 4y = 12
Subtract 6x from both sides :
-4y = 12 - 6x
Divide both sides by -4 :
[tex]y=-\frac{3(x+2)}{2}[/tex]

What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
The value of X increased by 35%.
Here, we will use the percentage formula.
The value is increased by 35%.
That means,
100 + 35 = 135%
135% in decimal form is 1.35.
In expression form as subject to X,
X(1.35)
In expressed form,
= X + 0.35X
= 1.35X
Therefore, equivalent expressions are 1.35X and (1+0.35)x.

After swimming 60 feet below the surface of water, a whale swims up 30 feet. Use a number line to help you create an equation that shows the new location of the whale in relation to the water service.
A. The equation is -60 + (-30) = -90. The whale is 90 feet below the waters surface.
B. The equation is -60 + (-30) = -30. The whale is 30 feet below the water surface.
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface.
D. The equation is -60 + 30 = -90. The whale is 90 feet below the water surface.
Answer:
C. The equation is -60 + 30 = -30. The whale is 30 feet below the water surface
Step-by-step explanation:
At the surface of the water in the swimming pool, the height of elevation is 0.
Thus, if you swim 60 ft below the surface, it means you are going in the negative direction when we consider a number line. Thus, distance = -60 ft
Now, when you swim back up by 30 ft, it is in the positive direction. Thus, total distance is now; -60 + 30 = -30 ft
Thus value denotes a negative direction and it means you are 30 ft below the surface of the water.

Step-by-step explanation:
There are 6 marbles that are either red or green out of 12 total marbles, so you have:
6/12 = 1/2
Answer:
1/2
Step-by-step explanation:
To find the probability, you need to put the number of what you want to know the probability of over the total. In this case, we want to know what the probability of red and green over the total is. So, hence the equation:

Find the area of the trapezoid by decomposing it into other shapes
Answer:
60 cm ( squared )
Step-by-step explanation:
you can find the area of the trapezoid ( by decomposing it into other shapes ) by separating two triangles, and using the formula to find the area of triangles, which is A= 1/2 ( b x h ) and add the answer to those together ( 16 cm squared and 4 cm squared ), and after that, you can find the area to the rectangle by multiplying the l x w, which is 10 x 4 ( after separating the triangles.). That equals 40, and when you add them all together ( 16 + 4 + 40 ) it equals 60 cm (squared).

Alright. Let's start.
(4ad) - [tex]\frac{1}{13}[/tex]b * [tex]\frac{16a}{13abc}[/tex] -1 is the expression.
So, by PEMDAS, we need to do the multiplication first. We can also say that 1/13b is the same as b/13.

Find the missing value to the nearest hundredth cos=4/38
Answer:
83.96 (approximately)
Step-by-step explanation:
I am not completely sure what the problem is asking, just like the last one, but I believe that you are just supposed to take the inverse of cosine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then cosine. You use the inverse of cosine when two sides are given, but you are not given the angle.
It should look like:
[tex]cos^{-1}(\frac{4}{38})[/tex], which is approximately 83.96.
Hopefully this is right, if not, please let me know. Good luck.

1) A puppy eats a sausage 5 seconds faster than a kitten eats an identical sausage. If they share one sausage, they can eat it in 6 seconds. How long does it take each animal to eat a sausage alone?
2) A tourist ignores the warning signs and leaves food in his car while he goes for a hike. A mama bear and her cub open the car door in 6 seconds. How long would it take each bear to open the car door alone if the cub needs 9 more seconds than the mama bear?
3) A superhero and his sidekick simultaneously leave the city and fly toward a secret hideout that is 1800 km away. The superhero's speed is 100 km/h slower than the sidekick's speed, and so he arrives at the hideout 36 minutes after his sidekick. Find the speed of each.
4) A bear loves visiting his friend, the piglet. The distance between their houses is 300m, and the bear always walks from his house to the piglet's house in exactly the same amount of time. But today, the bear stops at a beehive after walking 1/4 of the distance. He eats honey for 2.5 minutes and then continues to the piglet's house at a speed 15 m/min faster than usual. The total journey to the piglet's house takes the exact same amount of time as it usually does, when the bear does not stop for honey. How long does the journey take?
Answer:
1) The puppy takes 10 minutes, the kitty takes 15 minutes.
2) The mama bear takes 9 minutes, the cub takes 18 minutes
3) The sidekick goes at 600 mph, the hero goes at 500 mph.
4) 10 Minutes
5) RSM is so hard, amiright?
Step-by-step explanation:
1) You can simplify the word problem into the equation 1/x + 1/x+5 = 1/6. For problems like these, you have to simplify the last part to a fraction, not a whole number. Then you just solve.
2) Same thing. 1/x + 1/x+9 = 1/6. Solve. Boom. Done.
3) A bit different, but it simplifies to 1800/x-100 - 1800/x = .6. Solve. C'mon, you should've been able to do this one.
4) Harder, simplifies to 75/x+225/x+15+2.5 = 300/x. You get the last part because the time the bear took is equal to the time it would normally take, which is the entire distance over the normal pace. Then you solve and there we go, most of your RSM homework is done.
Answer:
Puppy takes 10 sec.
Kitty takes 15 sec.
The mama bear can do it in 9 seconds
The cub can do it in 18 seconds
Superhero: 500 km/h
Sidekick: 600 km/h
