4x +1 = -47
I’ve been trying to find this out for a while now and I simply just can’t
Answer:
Step-by-step explanation: your goal is to keep x on one side and everything else on the other.
subtract 1 from both sides
4x = -48
divide 4 on both sides
x= -12

2x – 4 + x
Is the expression simplified?
Simplified
Not Simplified
Answer:
Not simplified
Step-by-step explanation:
Because there is 2x and x where you add it up to get 3x
______________________________
1.) Combine 2x and x:[tex]2x+x=3x[/tex]- To simplify this, all you have to do is combine like terms. In this case you have 2 [tex](x)[/tex] variables. So you just add/subtract them.
So your answer is [tex]\bold{x+4}[/tex].

Part A
Using opposite operations, rewrite the equation so s2 is on one side of the equation by itself.
Part B
What is the opposite operation of squaring? Using this opposite operation, rewrite the equation from question 1 so s is by itself on one side of the equation.
Part C
The pyramid of Khufu, also known as the Great Pyramid of Giza, is one of the Seven Wonders of the World. Its volume is about 2,433,400 cubic meters, and its height is about 138 meters. Substitute these values into the equation from Part B, and solve the equation.
Part D
Search the Internet to find the length of each side of the base of Khufu’s pyramid. Does this length match your calculation?
Part E
Khafre was a son of Khufu. He also had a pyramid built, but it was not as big as his father’s. The volume of the Pyramid of Khafre is about 2,115,072 cubic meters, and its height is about 136 meters. Approximate the length of each side of the base?
Part F
Search the Internet to find the length of each side of the base of Khafre’s pyramid. Does this match your calculation?
Part G
About how much longer are the side lengths of the base of Khufu’s pyramid than Khafre’s?
Answer:
Part A: S^2= 3V/H
Part B: S =[tex]\sqrt{3\frac{v}{h} }[/tex]
Part C: s=√3* 2,433,400 /138=230 metres
Part D: This website says that the length of Khufu's Pyramid is about 230 meters. My calculation was correct.
Part E: S = √3*2,115,072/ 136 =216 metres
Part F: The length of Khafre's pyramid is about 215.5 My calculation was a little off, but not by much.
Part G: 14 meters longer
Step-by-step explanation:
Part A:
I am going to solve:
So,
V=1/3 [tex]HS^{2}[/tex]
Then, multiply both sides by 3:
V x 3= 1/3 [tex]HS^{2}[/tex] x 3
So,
3V=[tex]HS^{2}[/tex]
Then, we divide by H:
[tex]\frac{3V}{H}[/tex]=[tex]\frac{HSs^{2} }{H}[/tex]
So,
[tex]\frac{3V}{H}[/tex]= [tex]s^{2}[/tex]
Then switch sides:
[tex]s^{2}[/tex]= [tex]\frac{3V}{H}[/tex]

Sam decided to go to the amusement with his sister. He paid $10 for parking and $12.50 per ticket. Determine the y-intercept. Write your answer as an ordered pair (x,y).
Answer:
[tex]y= 10+12.5x[/tex]
Step-by-step explanation:
Given data
He paid $10 for parking and
$12.50 per ticket.
let the number of tickets be x
and let the total cost be y
Hence the expression in terms of x and y is
[tex]y= 10+12.5x[/tex]
Show that the lines
y = 4x + 2 and 8x + 2y = -3 are parallel
help pls asap ty ! ! !
Answer:
They intersect
Step-by-step explanation:
We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel.
Here we have two functions:
1) y = 4x + 2
2) 8x + 2y = - 3
2y = - 8x - 3
// divide both sides by 2
y = - 4x - 1,5
- 4 ≠ 4 , so these lines aren't parallel, maybe you wrote the assignment incorrect (e. g. if there would be " - " before 8 in the second function, those lines would be parallel), here they intersect.
-8>4+2v
How do you do this
Answer:
Step-by-step explanation:
-8 > 4 +2v ; subtract 4 from both sides
-8-4 > 4-4 +2v; calculate
-12 > 2v; divide both sides by 2
-6 > v
TO Know:
apply the same operation to both sides of inequality
if the operation is dividing or multiplying by a negative number change the direction of the inequality

Which of the following is not a recommendation the author of the Businesstown.com article makes to lower your
break-even point?
a. increase prices (4-5%)
b. increase operational capital with a bank loan
c. lower fixed expenses (phone, electric, advertising)
d. lower direct costs (labor, purchasing, controlling, inventory)
Answer:
b
Step-by-step explanation:
increase operational capital with a bank loan
Increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.
What are Expenses?An expense is an item requiring an outflow of money, or any form of fortune in general, to another person or group as payment for an item, service, or other category of costs.
In the article from BusinessTown.com, the author recommends several strategies to lower the break-even point of a business, which is the point where total revenue equals total expenses. The lower the break-even point, the easier it is for a business to make a profit.
Increase operational capital with a bank loan is not a recommendation to lower the break-even point.
Instead, it suggests borrowing more money to finance operations, which can increase the break-even point and the amount of revenue needed to cover expenses.
Hence, increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.

You survey the students in your class to find out what kinds of movies they
like to watch. The students were given the following choices: Comedy (C),
Horror (H), Drama (D), Action (A), Romance (R).
The following were the results of your survey:
C, C, R, R, D, R, H, H, C, A, A, R, A, A, A, R, R, H, H, H, C, H, A, R, D, D, D, D, H, R
Answer:
26% for romance and look in the explanation for other answer
Step-by-step explanation:
So to find a relative frequency you add up everything. so 30 for the results all together then you take whatever it focuses on and turn it into a fraction.
For question F it would be 8/30 or .26%
Then for the next answer the most popular movie genre would be romance at 26%.
Question H is more likely to pick for a movie which would least likely be comedy because its the lowest in the class at 13%

Question 1
What value of v makes the
equation true?
5(5 + 5v) =-29 + 7v
Answer:
v = -3
Step-by-step explanation:
5 (5 + 5v) = -29 + 7v
or, 25 + 25 v = -29 + 7v
or, 25 + 29 = 7v - 25 v
or, 54 = - 18v
or, v = -54/18
or, v = -3
for checking ( putting the value of v in both sides )
5( 5 + 5 (-3))= -29 + 7 (-3)
or, 5 ( 5 - 15 ) = -29 -21
or, 5 (-10) = -50
or, -50 = - 50
the equation is true
hope it will help you ☺✌
Answer:
v = - 3
Step-by-step explanation:
Given
5(5 + 5v) = - 29 + 7v ← distribute parenthesis on left side
25 + 25v = - 29 + 7v ( subtract 7v from both sides )
25 + 18v = - 29 ( subtract 25 from both sides )
18v = - 54 ( divide both sides by 18 )
v = - 3

Answer:
It loses -0.04 milliliters per minute.
Step-by-step explanation:
The pipe loses 1 1/5 milliliters (I'mma just call it ml from now on) every 30 minutes. The question is asking how many ml it loses every one minute. To find this, divide 1 1/5 ml by 30. This is very difficult with fractions tho, so convert the fraction into a decimal. (1 1/5 as a decimal is 1.2) Then divide 1.2 by 30 and you get -0.04 ml per minute.
Make sure you put that it loses *negative* 0.04 ml per minute!
