Answer:
x = 4.5
Step-by-step explanation:
Let's solve this together!
First you would want to multiply 6 and x:
6×2 = 12
x×2 = 2x
Then you would want to subtract 12 from 3:
3+12 = 9
Then divide 9 by 2:
9÷2 = 4.5
x=4.5
That's it!
Hope this helped! :)
A student earned a grade of 70% on a math test that had 20 problems. How many problems on this test did the student answer correctly?
9514 1404 393
Answer:
14
Step-by-step explanation:
Assuming the grade is proportional to the number of problems answered, we have ...
a/20 = 70/100
a = 20(0.70) = 14 . . . . multiply by 20
The student answered 14 problems correctly.

Calculate the measure of ∠ PMU and ∠ UPM.
m∠ PMU =
m∠ UPM =
Answer:
you want to find angle PMB to find PMU
180-21-35= 124
so now, you subtract 180-124 to find PMU
180-124= 56
Now, subtract 56 and 62 from 180 to find angle UPM
180-56-62= 62
m< PMU = 56
m<UPM = 62
Step-by-step explanation:
So we know that a triangle adds up to 180 degrees. Take 62+35 and subtract it from 180 to find angle P.
62+35=97
180-97=83
Knowing this you can find the two angles of P. You can subtract this number from 21 to find the unknown angle of P.
83-21=62(angle UPM)
Then do the same steps for finding the M angles
(Left Triangle)
62+62=124
180-124=56
(Right Triangle)
21+35=56
180-56=124
And because M intersects a straight line, the M angles should add up to 180.
56+124=180

Solve for x:
2x - 14 = 3x + 6
Answer:
x = - 20Step-by-step explanation:
[tex]2x - 14 = 3x + 6[/tex]
Move 3x to the other side of the equation
[tex]2x - 3x - 14 = 6 \\ - x - 14 = 6[/tex]
Move -14 to the right side of the equation.
[tex] - x = 14 + 6 \\ - x = 20[/tex]
Multiply both sides by - 1
[tex] - ( - x) = - 20 \\ x = - 20[/tex]
We have the final answer as
x = - 20Hope this helps you
Answer: add 14 to both sides of the equation
2x-14=3x+6
2x-14+14=3x+6+14
Simplify
add the numbers
2x-14+14=3x+6+14
2x=3x+6+14
add the numbers
2x=3x+6+14
2x=3x+20
subtract 3x from both sides of the equation
2x=3x+20
2x-3x=3x+20-3x
simplify
Combine like terms
2x-3x=3x+20-3x
-x=3x+20-3x
Combine like terms
-x=3x+20-3x
-x=20
Divided both sides of the equation by the same term
-x=20
-x/-1=20-/-1
Simplify
Cancel terms that are in both the numerator and denominator
-x/-1=20/-1
x=20/-1
Divide the numbers
x=20/-1
x=-20
So the answer is x=-20
Hope this helps... Stay safe and have a great day/night!!! :D

The population in Smalltown in 2010 was 45,230 people and is growing exponentially at a
rate of 2%. What will the population be in 2030?
O 67,475
O 81.928
O 67.209
O 82.414
Answer:
The first option
67475
Step-by-step explanation:
Step one:
Given data
The population in Smalltown in 2010 was 45,230
rate= 2%= 0.02
time t= 20 years
Step two:
Let P(t) = population t years after 2010
= 45230e^0.02t
Population in 2030 = P(20)
= 45230e^0.02t(20)
= 45230e^0.4
≈ 67475

A person invests 9500 dollars in a bank. The bank pays 5% interest compounded annually. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 13200 dollars?
Answer:
6.58 years
Step-by-step explanation:
Step one:
Given data
Principal=$9500
rate= 5%= 0.05
Final amount= $13200
Required:
The time t
Step two
The expression for the compound interest is
[tex]A= p(1+r)^t[/tex]
t = ln(A/P) / r.
substitute
t = ln(13200/9500) /0.05
t= ln(1.39)/0.05
t=0.329/0.05
t=6.58 years

Give an example of an equation that has no solution equation and explain why it is a no solution equation.
Answer:
x = x + 7
Step-by-step explanation:
In this equation, it is saying that x is equal to itself plus something else (7). This equation does not make sense at all because x cannot equal to something that is bigger or smaller than itself. If 7 is added to x, like the right-hand side of the equation, it cannot be equal to x from the left-hand side of the equation, so there is no solution to the value of x in this equation.

The length of a rectangle is 5 less than 3 times its width. The perimeter is
78. Find the LENGTH.*
Answer:
The length is 28 and the width is 11
Step-by-step explanation:
To solve this problem, we can make the width as x.
Since the length is 5 less than 3 times the width, it's going to be 3x - 5
So now we've got the length and width, just need to find the perimeter, which is all the sides added up together. They already gave us the perimeter, so we just have to solve the equation:
2(3x - 5) + 2x = 78
6x - 10 + 2x = 78
8x - 10 = 78
8x = 88
x = 11
x = 11, but remember, x is the width, not the length. Since we already found what x is, we just have to plug it into the equation of:
3x - 5
3 × 11 - 5
33 - 5 = 28
Answer: Length = 28 (don't forget to add the unit if there is one)
Lin was looking at the equation 2x−32+4(3x−2462)=14x. She said, “I can tell right away there are no solutions, because on the left side, you will have 2x+12x and a bunch of constants, but you have just 14x on the right side.” Do you agree with Lin?
Answer:
Disagree with Lin: There are no solutions because 12x+2x is equal to 14x, if 14x=14x on both sides, the x variable can be cancelled out since they have the same slope
Step-by-step explanation:
I agree with Lin the system of equation 2x - 32 + 4(3x - 2462) = 14x
has no solution.
What are the three types of solutions for a system of linear equations?If a system of equations only contains two linear equations with two variables, the system's equation can be graphed, the graph will have two straight lines, and the intersection point(s) of those lines will be the system's solution.
There are only three matching forms of solution for a given system of equations because there are only three different ways that two straight lines in the plane can graph.
Given, An equation 2x - 32 + 4(3x - 2462) = 14x.
2x - 32 + 12x - 9848 = 14x.
14x - 9880 = 14x.
So, 14x - 9880 ≠ 14x and has no solution.

Jonathan opened a savings account with $5500 and made no further
deposits. If the account pays3.5% simple interest, how long will it take until
the value of his account reaches $6655? *
a. 3.5 years
b. 6 years
c. 5.54 years
d. 6.5 years
It takes 6 years to reach $6655.
What is Simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
The formula written out is "Simple Interest = Principal x Interest Rate x Time."
Given:
Amount= 6655
Principal = 5500
Interest rate= 3.5%
So, Amount= P( 1 +rt)
6655 = 5500 (1 + 0.035t)
6655/5500 = 1 +0.035t
1.21 - 1= 0.035t
0.21 / 0.035 = t
t= 6 years
Hence, it takes 6 years to reach $6655.

Answer A is Linear. You can see this because each term is equal to the previous term plus a fixed amount (3), making it an arithmetic sequence.
Answer B is not linear. This is because each term is a multiple of the previous one, making it a geometric sequence.
Answer:
Function A
Step-by-step explanation:
Each time x increases by 1, y increases by 3. Function B is exponential instead of linear, because y increases by a larger number each time rather than increasing by the same amount.

Answer:
A) y = -1/2x + 2
Step-by-step explanation:
The line is negative, so you will have a negative slope
The line is crossing the y- axis at 2 so the y- intercept is 2.
Now do rise over run or rise/run
The lines rise is 2 and the run is 4
2/4 = 1/2 and since the line is negative the slope is negative -1/2
y = -1/2x + 2
