Solve 6x+8+7x-9=90 this is pretty hard tbh
Answer:
x=7
Step-by-step explanation:
6x+8+7x-9=90
13x+8-9=90
13x-1=90
add 1 to both sides
= 13x=91
divide both sides by 13
= x=7

What is $25.49 marked down 45% please help
Answer: $14.02
Step-by-step explanation:
Marked down by 45% means it will have a 45% percent discount.
Subtract 45% from 100% then multiply it by the amount .
100% - 45% = 55%
55% * 25.49 = 14.0195 Round it to the nearest hundredth to convert it to money.
14.0195 = 14.02

w many adult tickets were sold?
380 adult tickets.
640 divided into the sub categories of student and adults would be 320. at this point you don't even have to do any of the math for students because you already know there would be 60 less student tickets so you can just add the 60 to 320 for adults. So 380

Write a function to describe each arithmetic sequence
10, 14, 18, 22
Answer:
The function that describes the arithmetic sequence is A(n) = 4n + 6
Step-by-step explanation:
The formula of the arithmetic sequence is a[tex]_{n}[/tex] = a + (n - 1)d, where
a is the first term of the sequenced is the common difference between each 2 consecutive termsn is the position of the number∵ The terms of the sequence area 10, 14, 18, 22
∵ The first term is 10
∴ a = 10
∵ 14 - 10 = 4
∵ 18 - 14 = 4
∵ 22 - 18 = 4
∴ The common difference is 4
∴ d = 4
→ Substitute them in the formula above
∵ a[tex]_{n}[/tex] = 10 + (n - 1)4
∴ a[tex]_{n}[/tex] = 10 + n(4) - 1(4)
∴ a[tex]_{n}[/tex] = 10 + 4n - 4
→ Add the like terms
∵ a[tex]_{n}[/tex] = 4n + (10 - 4)
∴ a[tex]_{n}[/tex] = 4n + 6
→ Write it in the form of the function A(n)
∴ A(n) = 4n + 6
∴ The function that describes the arithmetic sequence is A(n) = 4n + 6

Find the measure of one exterior angle of each regular polygon. Round to the nearest tenth if necessary
Answer:
40 degrees
Step-by-step explanation:
360/9=40
The solution is 40°
The measure of one exterior angle of a nonagon is is given by the equation A = 360°/9 and the measure of A is 40°
What is the sum of an exterior angle of a polygon?
The sum of exterior angles in a polygon is always equal to 360 degrees. Therefore, for all equiangular polygons, the measure of one exterior angle is equal to 360 divided by the number of sides in the polygon. The sum of an interior angle and its corresponding exterior angle is always 180 degrees since they lie on the same straight line
Sum of exterior angles of a polygon = 360°
Measure of each exterior angle = 360° / N
where N is the number of sides
Given data ,
Let the measure of each exterior angle be = A
Let the number of sides of the polygon be = N
Now , the polygon is a nonagon
So , the number of sides N = 9
Now , The sum of exterior angles of a polygon is 360°
So ,
The measure of each exterior angle is given by the equation 360° / N where N is the number of sides
Substitute the value for N in the equation , we get
The measure of each exterior angle = 360°/9
The measure of each exterior angle = 40°
Therefore , the value of A is 40°
Hence , the measure of each exterior angle is 40°

» Which pair of numbers has an LCM of 60?
2 and 12
5 and 12
6 and 12
3 and 12
Answer: 5 and 12
Step-by-step explanation:
2 and 12 is not it because 12 can be divided by 2 meaning that the LCM of those two numbers will be 12.
6 and 12 is not it because 12 can also be divided by 6 meaning that the LCM of 6 and 12 is also 12.
3 and 12 is also the same, 12 can be divided by 3 so their LCM will be 12.
With 5 and 12, 12 is not divisible by 5 so you will have to find the multiples of 5 and 12 and it will eventually be 60.
Multiples of 5: 5, 10,15,20,25,30,35,40,45,50,55,60,65
Multiples of 12: 12, 24, 36, 48, 60, 72
As it appears in both multiples, 60 is the least number that appears in both multiples so the LCM of 5 and 12 is 60.
Answer:
It's 5 and 12

Mrs. Villa bought 2 packages of buttons. Each package had a different number of buttons. The table lists the number of buttons of each color in each package.
Answer:
B
Step-by-step explanation:
By applying basic formula of probability we got that statement "The probability of randomly selecting a green or a black button from Package L is equal to the probability of randomly selecting a red button from Package M." is True
What is probability ?Probability means chances of an event to occur .
Probability = favourable outcome /the total number of possible outcomes.
Total button in package L= 50
Total button in package M= 30
(a)
Probability of selecting green or black button from package L= (8+7)/50
=15/50=3/10
Probability of selecting red button from package M=9/30 = 3/10
Hence statement is true
(b)
Probability of selecting black button from package L= 7/50
Probability of selecting black button from package L=8/50
Hence statement is false
(c)
Probability of selecting red button from package L=12/50=6/25
Probability of selecting green button from package M=6/30=1/5
Hence statement is false
(d) Probability of selecting yellow button from package L=10/50=1/5
Probability of selecting yellow or green button from package M=9/30=3/10
Hence statement is false .
By applying basic formula of probability we got that statement "The probability of randomly selecting a green or a black button from Package L is equal to the probability of randomly selecting a red button from Package M." is True .

In rectangle PLAN, PT = x + 3 and TL = 3x - 11. What are the lengths of PA and NL?
Answer:
PA = 20 units
NL = 20 units
Step-by-step explanation:
Property of a rectangle,
"Diagonals of a rectangle are equal in measure and divide each other in two equal parts"
By using this property,
PT = TL
(x + 3) = (3x - 11)
3x - x = 11 + 3
2x = 14
x = 7
Length of PT = (x + 3) = 10
Length pf PA = 2(PT) = 20 units
Length of NL = PA = 20 units
