Answer:
-49/50
Step-by-step explanation:
-39v=4v+7(v+7)
Distribute
-39v = 4v +7v+49
Combine like terms
-39v = 11v+49
Subtract 11 v from each side
-39v-11v = 11v-11v +49
-50v = 49
Divide by -50
-50v/-50 = 49/-50
v = -49/50
Answer:
v= - 49/50
Step-by-step explanation:
-39v=4v+7(v+7)
open the parentheses by multiplying both v&7 by 7:
-39v=4v+7v+49
add like terms:
-39v-4v-7v=49
-50v=49
divide both sides by -50:
v= - 49/50

A pod of dolphins contains 800 dolphins of different ages and lengthens. The median length of dolphins in this pod is 5.8 feet. What info does does this tell you about the length of dolphins in this pod?
The median represents the middle value of the data 5.8 feet will be the middle value.
What is the median?The median represents the middle value in a dataset. The median is important because it gives us an idea of where the center value is located in a dataset. The median tends to be more useful to calculate than the mean when a distribution is skewed and/or has outliers.
Given that apod of dolphins contains 800 dolphins of different ages and lengthens. The median length of dolphins in this pod is 5.8 feet.
From the definition, we can see that of the 800 dolphins the length of the middle dolphin is 5.8 feet because it is a median and the upper values will be greater than 5.8 feet and below it all the dolphins will have smaller lengths.
Therefore, the median represents the middle value of the data 5.8 feet will be the middle value.

The equipment elevator descends 4 feet per second. The elevator for the miners descends 17 feet per second. The equipment elevator descends. After 25 seconds, the elevator for the miners begin to descend. What is the position of each elevator relative to the surface after another 12 seconds? At that time. Which elevator is deeper?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Equipment elevator Descent = 4 fts per Second
Miners elevator descent = 17 ft/sec
Miner's elevator begins descent 25 seconds after equipment elevator :
Elevation after another 12 seconds :
Descent = (speed * time)
Equipment elevator = 4 * (25 + 12) = 148 ft descent
Miner's elevator = 17 * 12 = 204 ft descent
The Miner's elevator is deeper at 204 feets.

Find pairs of points with a slope of ²/₅
Answer:
Look below
Step-by-step explanation:
To find a slope with 2/5, you can use y2 - y1/x2 - x1. The 1 and 2's can be different but you cannot mistake the x and y.
1st example:
(1, 5), (6, 7)
Reason: (7-5)/(6-1) = 2/5
2nd example:
(2, 8), (7, 10)
Reason: (10 - 8)/(7 -2) = 2/5
3rd example:
(5, 2), (10, 4)
Reason: (4-2)/(10 -5) = 2/5

Explain what is square root in simple form using example.
If something is written in its simplest radical form, that means that you have already found all possible roots and eliminated any radicals from the denominator of a fraction. ... For example, if your fraction is 2/√7, multiply by √7/√7 to get 2√7/√49. This will simplify to 2√7/7. hope this helps
Answer:
Square roots are the opposite of “squaring” a number, or multiplying it by itself. For example, three squared is nine (3 2 = 9), so the square root of nine is three. In symbols, this is √9 = 3. The “√” symbol tells you to take the square root of a number, and you can find this on most calculators.

Jordan already knew 2 appetizer recipes before starting culinary school, and he will learn 2 new appetizer recipes during each week of school. Write an equation that shows the relationship between the number of weeks w and the number of appetizer recipes a. Write your answer as an equation with a first, followed by an equals sign
Answer:
w=2r
r= w/2
r- w/2 = 0
w -2r= 0
Step-by-step explanation:
Let w be the number of weeks and r be the number of recipes learnt . So he will learn 2 recipes each week .Equating gives
w=2r
when w= 1
w= 2(1) = 2
For 1st week 2 recipes are learned
when w= 2
w= 2( 2) = 4
For 2nd week 4 recipes are learned.
or
when r= 2
r= w/2
r =2/2 = 1 one recipe is learned in half of the week
r- w/2 = 0
or
w -2r= 0

The student council has a budget of $100 to spend on the balloons for the holiday dance. They order from a company that charges $2 per ballon, plus a $12 delivery fee per order. The student council uses the inequality below, where b represents the number of balloons ordered, to determine if they have enough money to place an order for a specific number of books. 2b+12<100
Answer:
44 BalloonsStep-by-step explanation:
We are expected to solve for the total number of balloons they can get with $100
given that the expression for the total cost of balloons is given as
2b+12<100
We can proceed to solve for the total number of balloons they can buy, by solving for b we have
2b+12=100
2b=100-12
2b=88
divide both sides by 2 we have
2b/2=88/2
b= 44
Therefore they would get a total of 44 balloons

The mass of a teapot and 4 cups is 1,280 grams. The mass of the same teapot and 10 cups is 2,720 grams. Each cup has the same mass. What is the mass of the teapot?
Answer: 320 grams
Step-by-step explanation:
Let the mas of the teapot be denoted by a
Let the mass of the cups be denoted by c
The question can be turned into an equation which will be:
a + 4c = 1280 ......... equation i
a + 10c = 2720 ........ equation ii
Subtract equation i from ii
6c = 1440
c = 1440/6
c = 240 grams
The mas of the cup is 240 grams
From equation i
a + 4c = 1280
a + 4(240) = 1280
a + 960 = 1280
a = 1280 - 960
a = 320 grams
The mass of the teapot is 320 grams

Solve for the value of x that makes lines a and b parallel.
Answer:
x=16
Step-by-step explanation:
if the lines were parallel then that means that (7x+2) = (8x-14) because they are corresponding angles. just isolate the varible so subtract 7x from both sides and add 14 to both sides. and they you get x=16

what is 2x+54+4x-6=180
Answer:
=22
Step-by-step explanation:
Subtract the numbers
2+54+4−6=180
2+48+4=180
Combine like terms
2+48+4=180
6+48=180
Subtract 48 from both sides of the equation
6+48=180
6+48−48=180−48
Simplify
Subtract the numbers
Subtract the numbers again
6=132
Divide both sides of the equation by the same term
6=132
6/6=132/6
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
=22
Solution
=22
