Answer:
[tex]x=20[/tex]
Step-by-step explanation:
We have been a triangle has one angle measuring [tex]3x[/tex] degrees the second angle measures [tex]2x+20[/tex] degrees and the third angle measures [tex]4x-20[/tex] degrees. We are asked to find the value of x.
We know that all interior angles of a triangle add up-to 180 degrees.
[tex]3x+2x+20+4x-20=180[/tex]
Combine like terms:
[tex]3x+2x+4x-20+20=180[/tex]
[tex]9x=180[/tex]
Divide both sides by 9:
[tex]\frac{9x}{9}=\frac{180}{9}[/tex]
[tex]x=20[/tex]
Therefore, the value of x is 20 for our given triangle.

What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
The fraction [tex]2\frac{3}{8}[/tex] can be written as 19/8
Let x be the number added to given fraction, that is
19/8 +x=6
⇒ x=6-19/8
⇒ x= (48-19)/8
⇒ x= 29/8
⇒ x= [tex]3\frac{5}{8}[/tex]
Hence, the number must be added to [tex]2\frac{3}{8}[/tex] to make 6 is [tex]3\frac{5}{8}[/tex].

Rose's stamp collection is 7 less than half of Van's stamp collection, x.
Which expression represents the total number of stamps that Rose has?
The expression representing Rose's stamp collection is given by R = (1/2)x - 7. It denotes that Rose's collection is 7 less than half of Van's stamp collection, where x represents the total number of stamps in Van's collection.
Let's denote Van's stamp collection as x. According to the given information, Rose's stamp collection is 7 less than half of Van's stamp collection.
Expression for Rose's stamp collection (R):
R = (1/2)x - 7
Here's the breakdown of the expression:
(1/2)x represents half of Van's stamp collection.
-7 signifies 7 less than half of Van's stamp collection.
This expression encapsulates the relationship between Rose's stamp collection and half of Van's collection, diminished by 7.
Which function represents a horizontal shift of f(x)=5^x by 4 units to the right?
Answer: [tex]g(x)=5^{x-4}[/tex]
Step-by-step explanation:
When a function f(x) is shifted horizontally by n units to the right , the new function will become :-
[tex]g(x)=f(x-n)[/tex]
The given function : [tex]f(x)=5^x[/tex]
Now, if the given function shifted 4 units to the right , then the new function will become :
[tex]g(x)=f(x-4)[/tex]
[tex]g(x)=5^{x-4}[/tex]
Hence, the function represents a horizontal shift of [tex]f(x)=5^x[/tex] by 4 units to the right will be :-
[tex]g(x)=5^{x-4}[/tex]
Sven is trying to find the maximum amount of time he can spend practicing the five scales of piano music he is supposed to be working on. He has 70 minutes to practice piano and would like to spend at least 55 minutes playing songs instead of practicing scales. So, Sven sets up the following inequality, where t is the number of minutes he spends on each scale, and solves it.
70 − 5t ≤ 55
−5t ≤ −15
t ≥ 3
Sven has concluded that he should spend 3 minutes or more on each scale. Is this correct? If not, what mistake did he make? Then solve for the correct answer.
Answer:
He should spend 3 minutes or less on each scale
Sven made a mistake in the symbol of inequality, placing lesser or equal instead of greater or equal
Step-by-step explanation:
Let
t ------> is the number of minutes he spends on each scale
Remember that the phrase "at least" is equal to "greater than or equal"
so
The inequality that represent this scenario is
[tex]70-5t \geq 55[/tex]
solve for t
[tex]-5t \geq 55-70[/tex]
[tex]-5t \geq -15[/tex]
Multiply by -1 both sides
[tex]5t \leq 15[/tex]
Divide by 5 both sides
[tex]t \leq 3[/tex]
Sven is incorrect
He should spend 3 minutes or less on each scale
Sven made a mistake in the symbol of inequality, placing lesser or equal instead of greater or equal

Jillian is selling boxes of cookies to raise money for her basketball team. The 10 oz. box costs $3.50, while the 16 oz. box costs $5.00. At the end of one week, she collected $97.50, selling a total of 24 boxes. The system of equations that models her sales is below. x+ y= 24 3.50x + 5.00y = 97.50 Solve the system of equations. How many 10 oz. boxes were sold?
Answer:
There are 15 boxes of 10 oz boxes
Step-by-step explanation:
Let the number of boxes of 10 oz = x
and let the number of boxes of 16 oz = y
By the statement
"Total number of boxes sold is 24"
Equation for the statement will be
x + y =24 ---------------(1)
By the statement
"she collected $97.50 while rate of 10 oz box is $3.50 and rate of 16 oz box is $5.00."
Equation for the statement will be
1.5x + 5y = $97.50 ------------(2)
From equation (1) we put the value of y = 24 - x in equation (2)
1.5x + 5(24 - x) = 97.50
1.5x + 120 - 5x = 97.50
-3.5x = 97.50 - 120
3.5x = 22.50
x = [tex]\frac{22.5}{1.5}[/tex]
x = 15
Therefore, number of 10 oz boxes is 15.

The change in the value of an account when given to the nearest dollar
The net change in the value of the account, when rounded to the nearest dollar, is $550.
To find the net change in the value of the account, you would sum up the amounts deposited, subtract the amounts withdrawn, and add the interest earned:
Net change = (Deposits - Withdrawals) + Interest earne
Net change = ($500 - $250) + $300
= $250 + $300
= $550
Therefore, the net change in the value of the account, when rounded to the nearest dollar, is $550.
The probable question maybe:
"What is the net change in the value of an investment account after depositing $500, withdrawing $250, and earning $300 in interest, when rounded to the nearest dollar?"
