8N+16.2 equals 1.6
help needed asap what do i do!!
Answer:
n=-0.425
Step-by-step explanation:
subtract 16.2 from both sides. divide 8 from both sides
Answer:
N= -1.825
Step-by-step explanation:
First, we must isolate the variable. So we can write 8N+16.2=1.6. Let's subtract 16.2 from both sides of the equal sign. So now we have 8N=-14.6. Now we have to only get N, so we must divide every side by 8. We do this to cancel out the 8 multiplying the N. We get N= -1.825. This is your answer!
I hope this helped you solve this problem and help you solve future problems!
Kenneth is 10 years older than Andrew. Billy is 2 times as old as Andrew. Cameron is 8 years younger than Andrew. The combined age of the four is 77. How old is each boy?
Answer:
Kennet 25,Andrew 15,Billy 30,Cameron 7
Step-by-step explanation:
Kenneth - 10+x,
Andrew - x,
Billy - 2x,
Cameron - x - 8,
10 + x + x + 2x + x - 8 =77
5x = 75
x = 15 (Andrew)
10+15= 25 (Kenneth)
2×15=30 (Billy)
15-8= 7 (Cameron)

What is the slope of the line graphed below? (5,3) (-5,5)
Answer:
3
Step-by-step explanation:
but im not sure
Answer:
m = 4/5 (slope)
_____________________________
y = 4/5x - 1 (slope intercept)(y = mx + b)
- 4x + 5y = - 5 (standard form)(Ax + By = C)
y + 5 = 4/5(x + 5) (point slope)(y - y1 = m(x - x1))
Step-by-step explanation:
All you need to do is remember the equation for slope: m = y2-y1/x2-x1
Where your first point is (x1,y1), and your second point is (x2,y2), and m is slope(rate of change : change in y over change in x).
Your first point starts with the smallest x: (-5,-5), then your second point is the greater x: (5,3)
Then just substitute, and solve:
y2-y1/x2-x1 →
3-(-5)/5-(-5) = 3+5/5+5 = 8/10 = 4/5
Extra information:
point slope:
y-y1 = m(x-x1).
Where (x1,y1) is the first point, (x,y) is the second point, and m is the slope. (note: the second point does not have 2 as a subscript so it can be set to slope intercept(y = mx + b) as an equation. This is because you could be given one point, and a slope, and be told to find the other)
Then just plug the coordinates into the equation, and solve for the equation of this line.
Since we already know what the slope is, we can just solve for the general equation given one point:
y-y1 = m(x-x1)
y+5 = 4/5(x+5). (point slope)
y + 5 = 4/5x + 4
-5 -5
____________
y = 4/5x - 1
(slope intercept)
Given slope, another way to find the y intercept is to multiply the current x coordinate by the slope, and add it to the current y value.
given a point (5,3), and a slope of 4/5. The line will be y = slope × x + (y2 - (m × x2)),
y = 4/5 × x + (3 - (4/5 × 5))
y = 4/5x + (3 - 4)
y = 4/5x - 1

how much money is 18 figures?
Answer:
2.
Step-by-step explanation:
I don't know if it is right but thats what i got. You didnt really give enough information for me to solve it.
We have that an 18 figure is a Quintilllion=10^{18}
18 figure=10^{18}
Quintilllion
From the question we are told
How much money is 18 figures
Generally the denominations of money is is mathematically given as
Hundred=100
Thousand=1000
Million=1000000
Billion=1000000000
Quintilllion=10^{18}
Therefore
Therefore and 18 figure is a Quintilllion=10^{18}
18 figure=10^{18}
Quintilllion

You are tasked with helping plan a school dance. You expect 110 people to attend the dance and need to provide seating for each person. The tables come in two different sizes. The smaller tables can fit 2 people, the larger tables can seat 4 people. Write an equation that describes the relationship between the quantity of small tables and the quantity of large tables, assuming exactly 110 people need seats.
Answer:
2x + 4y = 110
Step-by-step explanation:
Let
The quantity of small tables = x
The quantity of large tables = y
The smaller tables can fit 2 people, the larger tables can seat 4 people.
Equation that describes the relationship between the quantity of small tables and the quantity of large tables, assuming exactly 110 people need seats.
Number of people×quantity (small table) + number of people×quantity (large table) = 110
2x + 4y = 110

Ok think about it 1/4 plus 1/2 is 3/4
so how do i go to negitives?
you double the amount of it and then minus it
because 3/4- 3/4 would be zero
so you have to double it to get that answer

what is negative one eighth of a number is -3/4 as an equation?
will name the brainliest!
Answer:
The equation is [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex]
Step-by-step explanation:
The Equation is formed from two sides equal to each other
In the algebraic statement "is" means equalIn the algebraic statement "of" means times (×)∵ One eighth means [tex]\frac{1}{8}[/tex]
∴ Negative one eighth means [tex]-\frac{1}{8}[/tex]
→ Assume that the number is x
∵ "of" means times
∴ Negative one eighth of a number = [tex]-\frac{1}{8}[/tex] × (x)
∴ Negative one eighth of a number = [tex]-\frac{1}{8}[/tex] x
∵ Negative one eighth of a number is [tex]-\frac{3}{4}[/tex]
→ "is" means equal, so the left side is [tex]-\frac{1}{8}[/tex] x and the right side is [tex]-\frac{3}{4}[/tex]
∴ [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex] ⇒ Equation
∴ The equation is [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex]

If one x-value maps to many y-values, does the relation represent a function?
Answer:
No
Step-by-step explanation:
This is the general rule for any function, where a function cannot have more than one x value for every y value, there is only one output for every input.
You can also use the vertical line test which states that anything that hits the line more than once is not a function.
A family daycare center charges a $75 enrollment fee and $100 per week for a child to attend. Write the linear equation to model this situation.
Answer:
100x+75=y
Step-by-step explanation:
Answer:
y=100x+75. Where y equals total cost and x equals numbers of weeks enrolled.
Step-by-step explanation:
75 is the upfront cost, aka the cost of zero weeks, this cost will never change and is a one-time payment, therefore it needs no variable. 100 is the cost per week which means every week costs 100 more dollars, this is why it must have a variable because it will change with time. They are added together because they both show the total cost and together will show how much one person is spending.
