The amount of sales tax charged on the repaired computer at Store A is 72 dollars.
We have to given that,
A 3-column table with 4 rows.
Column 1 has entries Computer repair, sales tax, gratuity, shipping.
Column 2 is labeled Store A with entries 1,200 dollars, 6 percent, 15 percent, Free.
Column 3 is labeled Store B with entries 1,350 dollars, 7 percent, 15 percent, 2 percent of total price.
Hence, For store A,
The amount of sales tax charged on the repaired computer at Store A is,
6% of 1200
= 6/100 x 1200
= 6 x 12
= 72 dollars
Therefore, the amount of sales tax charged on the repaired computer at Store A is 72 dollars.

Students of an elementary school can wear only red or blue shirts. In one class of 28 students, 7 students are wearing blue shirts today and the rest of the students are wearing red shirts. What is the ratio of students wearing blue shirts to students wearing red shirts in that class today? Select each correct answer. Question 1 options: 1:7 7:21 7:28 For every student wearing a blue shirt, there were 3 students wearing red shirts. For every student wearing a blue shirt, there were 4 students wearing red shirts. For every student wearing a blue shirt, there were 7 students wearing red shirts.
Answer:
7:21 For every student wearing a blue shirt, there were 3 students wearing red shirts.
Step-by-step explanation:
If there are 28 students and 7 are wearing blue shirts then the number of students wearing red shirts is 28 - 7 = 21 so 21 students are wearing red shirts.
That means the ratio of blue shirts to red shirts is 7:21
That also means that for every student wearing a blue shirt, 3 were wearing a red shirt.

Write the equation for g(x)
Please answer I need help ASAP
==================================================
Explanation:
We're given that f(x) = x^2
The function g(x) is vertically stretched to be five times taller. We see this with the point (1,5) on the purple graph since its counterpart is at (1,1) on the blue graph.
We look at how the y values changed. So we had gone from y = 1 to y = 5. This jump means "multiply by 5"
If we do this to all the y values on the blue graph, then all the points jump to a height 5 times taller. Something like (2,4) moves to (2,20). Something like (3,9) goes to (3,45). And so on. This is what produces the purple g(x) graph.
You could say that
g(x) = 5*f(x)
g(x) = 5x^2
This works because y = f(x), so when we say 5*f(x), we really mean 5*y.

por favor ayúdenme en esta ecuación: 5x-3x=6x-8
Hey there!
ANSWER: [tex]x=2[/tex]EXPLANATION:[tex]5x-3x=6x-8[/tex]
Combine like terms.
[tex](5x+-3x)=6x-8\\2x=6x-8[/tex]
Subtract 6x from both sides of the equation.
[tex]2x-6x=6x-8-6x\\-4x=-8[/tex]
In the last step, we will divide both sides by -4.
[tex]\frac{-4x}{-4} =\frac{-8}{-4} \\x=2(ANSWER)[/tex]

Answer: x = 2
Step-by-step explanation: Aquí esta :
Simplificar 5x - 3x y eso se de 2x
1.) 2x = 6x-8
Sustraer 6x-2x
2.) 2x-6x= -8
Y entonces deberías haber obtenido 4x
3.) -4x=-8
Dividir ambos lados por -4
4.) x = -8/-4
Dos negativas hacen una positivo
5.) x = 8/4
Finalmente, la repuesta es :
6.) x = 2
Can you simplify 10/16?
Answer:
5/8
Step-by-step explanation:
-1=(5+x)/6
Please help me
Answer:
-11
Step-by-step explanation:
Answer:
[tex]x=-11[/tex]
Step-by-step explanation:
[tex]-1=\frac{\left(5+x\right)}{6}[/tex]
Switch sides:
[tex]\frac{\left(5+x\right)}{6}=-1[/tex]
Multiply both sides by 6:
[tex]\frac{6\left(5+x\right)}{6}=6\left(-1\right)[/tex]
[tex]5+x=-6[/tex]
Subtract 5 from both sides:
[tex]5+x-5=-6-5[/tex]
[tex]x=-11[/tex]

What is the perimeter of a rectangle that
has a length of 9 cm and a width of 6
cm?
A. 54 sq. cm B. 54 cm
C. 30 cm
D. 30 sq. cm
Answer:
The answer is option CStep-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
l = 9 cm
w = 6 cm
Substitute the values into the above formula and solve
We have
P = 2(9) + 2(6)
= 18 + 12
We have the final answer as
P = 30 cmHope this helps you
Answer: d.30cm
Step-by-step explanation:
the formula for perimeter is P=2L+2W
Substitute the length and width
P= 2(9)+2(6)
Multiply
P= 18+16
Add
P=30
Add the unit
P= 30cm

Simon is making a poster about friendship in his art class. He divides his poster into 3 equal parts. Simon writes the names of his friends all over each part. Simon uses 1 part for his neighborhood friends and 1 part for his friends from school.
What fraction of the poster does Simon use for his friends from school?
Answer:
1/3
Step-by-step explanation:
The most important thing to remember is that the poster is divided into three equal parts and 1 part of it is for his neighborhood friends and another one part of it is for his friends from school. The denominator would be three and the numerator would be the 1 part he uses for his friends from school.

I NEED HELP ASAP. BEFORE 4:00
Answer:
The measure of x = 45 degrees
Answer:
x is equal to 50.
Explanation:
The three lines intersect creating a triangle. All angle measures for triangles in Euclidean geometry must have a sum of 180 degrees. Because of the Vertical angles theorem, which states if two angles are opposite they are congruent, this means the angle across from 40 degrees is also 40 degrees. Since we know that the second angle is 90 degrees based on the right angle sign. By adding 40 and 90 you get a sum of 130. Now you subtract 130 from 180. This gives you 50 degrees. Since the Vertical angle theorem states two opposite angles are congruent we know the x is equal to 50 degrees.
6. -n + 7 - 2n + 5n - 3 = -6
Answer:
n = -5
Step-by-step explanation:
Step 1: Write equation
-n + 7 - 2n + 5n - 3 = -6
Step 2: Solve for n
Combine like terms: 2n + 4 = -6
Subtract 4 on both sides: 2n = -10
Divide both sides by 2: n = -5
