Explain how to solve the equation 3.5n = 10.5 , what is the value of n ?
Answer:
n=3
Step-by-step explanation:
Divide both sides by 3.5
n= 3.5 /10.5
Simplify 3.5 /10.5 to 3.
N=3
Answer:
n = 3
Step-by-step explanation:
Divide both sides by 3.5 to isolate n on one side.
[tex]3.5n=10.5\\\\\frac{3.5n=10.5}{3.5}\\\\\boxed{n=3}[/tex]

Leigh-Anne invests £2500 for 4 years in a savings account.
She gets 3% per annum compound interest.
How much money does Leigh-Anne have at the end of 4 years.
Answer:
After 4 years, Leigh-Anne will have £ 2,813.77 in her account.
Step-by-step explanation:
Given that Leigh-Anne invests £ 2500 for 4 years in a savings account, and she gets 3% per annum compound interest, to determine how much money does Leigh-Anne have at the end of 4 years, the following calculation must be performed:
X = 2,500 x (1 + 0.03 / 1) ^ 4
X = (2,500 x 1,003) ^ 4
X = 2,813.77
Thus, after 4 years, Leigh-Anne will have £ 2,813.77 in her account.

Solve for <6 pls :)) (Picture below)
Answer: 137°
Step-by-step explanation:
If you take the angle that is 43° and take 180°-43°
you get 137° this gives you angle 3 and since angle 3 and 6 are the same, angle 6 will equal 137°
Mike had 308 dollars to spend on 8 books. After buying them he had 12 dollars. How much did each book cost?
Answer:

y=2/3 x -20
y= 1/3 x +100
y= 2/5 x +2
y= 4/12 x
Answer:
the first one
Step-by-step explanation:
mx where m is the slope
2/3 > all the others
Answer:
y = 2/3x - 20
Step-by-step explanation:
The fraction in front of the X determines the slope
y = 2/3x - 20 has a slope of 2/3
y = 1/3x + 100 has a slope of 1/3
y = 2/5x + 2 has a slope of 2/5
y = 4/12x has a slope of 4/12
Y = 2/3 -20 has the biggest slope
You earn $320 in 40 hours. At this rate how many hours do you work to earn $440?
Answer:
60.5
Step-by-step explanation:
320/44=7.27
440/7.27=60.5
Answer: 55 Hours
Step-by-step explanation:
If you take 320 and divide it by 40
you get 8
This means you earn $8 for every hour you work.
Now if you take 440 and divide it by 8, meaning $440 dollars divided by $8
You will get
55, meaning you must work 55 Hours to make $440.

I used 9.8 pints of blue paint and white paint to paint my bedroom walls 4/5 of this amount is blue plate and the rest is wiping how many pints of white paint did you use to paint her bedroom walls
Answer:
searth it up duh
Answer:
Amount of white paint used to paint bedroom walls = [tex]1.96[/tex] pints
Step-by-step explanation:
Total amount of blue paint and white paint = 9.8 pints
Amount of blue paint used to paint bedroom walls = [tex]\frac{4}{5}[/tex]
Amount of white paint used to paint bedroom walls = [tex]1-\frac{4}{5}=\frac{1}{5}[/tex]
Therefore,
Amount of white paint used to paint bedroom walls = [tex]\frac{1}{5}(9.8)=1.96[/tex] pints

HELPPPPPPP pleaseeeeee it's a test!!!
Answer:
-18, -12, 0, 25, 5
0, -12, 5, -18, 25
25, 0, -18, 5, -12
-12, 25, 5, 0, -18
5, -18, 25, -12, 0
Step-by-step explanation:
The only values you need to use here are 0, 5, 25, -12, and -18.
I started with the bottom right box because the far right column only had one empty box. From the set of values I stated above, that column already had each of those numbers except for 0, so 0 would go in the bottom right box.
Another way to think about it is each row or column must have a 5 and a 25 to make 30, and a -12 and a -18 to make -30. Those two numbers cancel each other out to make 0, and then each row/column will include a 0 value which obviously wouldn't effect that balance. So the whole row/column will come out to be 0.
After figuring out that first bottom right box, go to the next row/column with only one empty box left (this happened to be the very bottom row), and use the same strategy to fill in the missing value.
Continue finding the next row/column with only one empty box left and figure out its missing value until you've completed the whole box.
The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds
600 people. By selling tickets, the members would like to raise $
3,300 every night to cover all expenses. Let d represent the number of adult tickets sold at $
7.50. Let s represent the number of student tickets sold at $
4.50 each. If all
600 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $
3,300? At one performance there were
two times as many student tickets sold as adult tickets. If there were
360 tickets sold at that performance, how much below the goal of $
3,300 did ticket sales fall?

Write the equation of the line in slope-intercept form with slope = 1/4 and point (-8, 6)
Step-by-step explanation:
This is the standard linear equation:
[tex]y=mx+b[/tex]
[tex]m[/tex] represents slope and [tex]b[/tex] represents the y-intercept. In a finished equation, [tex]x[/tex] and [tex]y[/tex] are left as variables. [tex]x[/tex] and [tex]y[/tex] represent any given point in the function. In this case, one of the given coordinates is [tex](-8, 6)[/tex], and we can use this by using [tex]-8[/tex] as [tex]x[/tex] and [tex]6[/tex] as [tex]y[/tex]. After plugging in known variable, the equation becomes this:
[tex]6 = \frac{1}{4} ( - 8) + b[/tex]
This simplifies to:
[tex]6 = - 2 + b[/tex]
Then to:
[tex]4=b[/tex].
After plugging in slope and y-intercept, the finished equation is:
[tex]y = \frac{1}{4} x + 4[/tex]

Step-by-step explanation:
pls help trigonometry is confusing to me :(
My first tip would be to label your triangles.
If you find our reference angle and go across, that would be our opposite side, so x is the opposite side.
The line with both the reference angle and the right angle would be our adjacent side, so 40 would be the adjecent side.
If you find the right angle and go across, that would be our hypotenuse.
//
In this problem, we are given an angle and the adjacent side and we are looking for the opposite side, so that means that we would be using our tangent ratio.
[tex]tan = \frac{opp}{adj} = \frac{x}{40} [/tex]
[tex] \tan(43) = \frac{x}{40} [/tex]
if the thing you are looking for is on the numerator, we would have to multiply. If the thing you're looking for is in the denominator, you would have to divide.
Since x is on the numerator, we would have to multiply.
[tex]x = 40 \tan(43 ) [/tex]
[tex]x = 37.3006034455[/tex]
[tex]x = 37.30[/tex]
