Step-by-step explanation:
fvccckkk school lol
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
2m - 5q = 8
4m + 2q = 64
The value of q in the solution to the equations is 4.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 3 = 4 is an equation.
2X = 4 is an equation.
We have,
2m - 5q = 8 ____(1)
4m + 2q = 64 _____(2)
From (1) we get,
2m = 8 + 5q
Divide both sides by 2.
m = (8 + 5q)/2 ______(3)
Now,
Putting (3) in (2) we get,
4m + 2q = 64
4/2 (8 + 5q) + 2q = 64
2 (8 + 5q) + 2q = 64
16 + 10q + 2q = 64
16 + 12q = 64
12q = 64 - 16
q = 48/12
q = 4
Now,
q = 4 in (3) we get,
m = (8 + 5q) / 2
m = (8 + 5 x 4) / 2
m = (8 + 20) / 2
m = 28 / 2
m = 14
Thus,
The value of q in the solution to the equations is 4.

ryan wants to buy a sweatshirt for $42.99. The sale tax rate in his city is 7 1/2% what is the total cost for the sweatshirt? round your answer to the nearest cent.
Answer:
Step-by-step explanation: Answer:46.21
Step-by-step explanation:t/42.99 = 7.5/100.
Butterfly method
42.99 x 7.5 = 322.42 divided by 100= 3.22 plus 42.99 = 46.21etc
The total cost for the sweatshirt is $46.21.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Ryan wants to buy a sweatshirt for $42.99.
The sale tax rate in his city is 7[tex]\frac{1}{2}[/tex]%.
Converting mixed fraction to improper fraction,
7[tex]\frac{1}{2}[/tex] = 15/2
Let n + 42.99 be the total cost of the sweatshirt.
n = 15/2 x 42.99 / 100
n = 322.425 / 100
n = 3.22
n + 42.99 = 46.21 to the nearest cent.
Therefore, the cost with sales tax is $46.21.

The ratio of males to females at a party is 3 : 5
There are 12 more females than males.
How many people are at the party?
Answer:
48
Step-by-step explanation:
Given ratio of males to females at a party is 3 : 5.
Let the numbers of males and females be 3x and 5x respectively.
According to the given description:
No of females = No of males + 13
Therefore,
5x = 3x + 12
5x - 3x = 12
2x = 12
x = 12/2
x = 6
No of people at the party
= 3x + 5x
= 8x
= 8*6
= 48

The quadrilateral below is a rhombus. Find the missing measures. Any decimal answers should be rounded to the nearest tenth.
NK =
m
NL =
m
ML =
m
JM =
m
m
Answer:
The answer is below
Step-by-step explanation:
If the quadrilateral below is a rhombus, find the missing measures.
MK = 24, JL = 20, and mZMJL = 50°
Solution:
A rhombus is a quadrilateral (has four sides and four angles) such that all the sides are of equal length.
The diagonals of a rhombus bisect each other.
NK = MK / 2 (diagonals of a rhombus bisect each other)
NK = 24 / 2 = 12
NL = JL / 2 (diagonals of a rhombus bisect each other)
NL = 20 / 2 = 10
In triangle MNL, ∠N = 90°
MN = NK = 12 , NL = 10. Using Pythagorean theorem:
ML² = MN² + NL²
ML² = 12² + 10²
ML² = 244
ML = √244
ML = 2√61 = 15.62
JM = ML = 15.62 (all sides of a rhombus are equal)
∠KNL = 90° (diagonals are perpendicular bisectors)
∠KJL = ∠MJL (diagonals bisect angles)
∠KJL = 50°
∠MJK = ∠KJL + ∠MJL = 50 + 50 = 100°
∠MJK = ∠MLK (opposite angles are equal)
∠MLK = 100°
∠NJK + ∠JNK + ∠JKM = 180° (sum of angles in triangle)
50 + 90 + ∠JKM = 180
∠JKM = 40°
∠JKL = 2 * ∠JKM (diagonal bisect angle)
∠JKL = 2 * 40
∠JKL = 80°
∠JKL = ∠JML (opposite angles are equal)
∠JML = 80°
PLEASE HELP DUE IN 5 MIN... Carson has a smart phone data plan that costs $40 per month that includes 2 GB of data, but will charge an extra $10 per GB over the included amount. How much would Carson have to pay in a month where he used 3 GB over the limit? How much would Carson have to pay in a month where he used went over by xx GB?
Answer:
a. $70
b. $(40 + 10x)
Step-by-step explanation:
The standard cost of the charges is $40 per month but an extra $10 per GB over the included amount.
a. Firstly the cost for a month in which he uses 3GB over the limit
we have a standard of $40, then he has to pay $10 per GB for the 3GB over the limit.
Thus the cost of the 3GB is $10 * 3 = $30
The total cost for using 3GB above the limit would be $40 + $30 = $70
b. For using x GB above the limit
He has to pay $10 per each GB above the limit
Thus, the amount to be paid for x GB above the limit would be x * $10 = $10x
So the total amount to be paid would be the base fee plus over the limit fee= $(40 + 10x)

Find the 9th term.
Answer:
The 9th term of the sequence is:
[tex]a_9=\frac{65536}{6561}[/tex]Step-by-step explanation:
Given the sequence
1, 4/3,16/9
computing the ratios of all the adjacent terms
[tex]\frac{\frac{4}{3}}{1}=\frac{4}{3},\:\quad \frac{\frac{16}{9}}{\frac{4}{3}}=\frac{4}{3}[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]r=\frac{4}{3}[/tex]
A geometric sequence has a constant ratio 'r' and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
As
[tex]a_1=1[/tex][tex]r=\frac{4}{3}[/tex]so substituting [tex]a_1=1[/tex] and [tex]r=\frac{4}{3}[/tex] in the nth term of the equation
[tex]a_n=a_1\cdot r^{n-1}[/tex]
[tex]a_n=\left(\frac{4}{3}\right)^{n-1}[/tex]
Now, substitute n = 9 to determine the 9th term
[tex]a_9=\left(\frac{4}{3}\right)^{9-1}[/tex]
[tex]a_9=\left(\frac{4}{3}\right)^8[/tex]
[tex]a_9=\frac{4^8}{3^8}[/tex]
[tex]a_9=\frac{65536}{6561}[/tex]
Therefore, the 9th term of the sequence is:
[tex]a_9=\frac{65536}{6561}[/tex]theres 2 questions and an image provided
1. if a= 6 and b=2 them what does a^b equal
2. according to the graph, which of these is true?
a. the later the day it is, the hotter it is
b. temperature goes up and then down during the day
c. temperature is always lowest in the evening
d. temperature decreases when it rains
Answer:
8). 36
10). Option 2
Step-by-step explanation:
8). If a = 6 and b = 2
Then [tex]a^{b}=6^{2}[/tex]
= 36
10). This graph has two parts.
First part shows the increase in the temperature with time in the morning.
Second part shows the decrease in the temperature in the evening.
So the graph represents the rise in temperature then down during the day.
Option 2 is the correct option.

16q3-48q2+32q what would be the steps on how to do this? please?
Answer:
Its nothing complicated, you just have to combine all the like terms, just make sure the lvariables are the same before combining of course.
so assuming the gaps missng are exponents
the solution is the same exact thing
it can’t be simplified anymore since 16q^3 or -48q^2 can’t due to different exponents which thefore can’t combine
same with 32 q, nothing combines
