Answer: 7
Step-by-step explanation:
3a + 4 = 21
Step 1 subtract 4 from both sides.
3a+4−4=25−4
3a = 21
Step 2: Divide both sides by 3.
3a / 3 = 1
21 / 3 = 7
a = 7
g(n)=-4n+2; find g(8)
Answer:
-30
Step-by-step explanation:
In g(8) the 8 = n. So, substitute 8 in for n in the expression -4n + 2
g(8) = -4(8) + 2 = -32 + 2 = -30
Answer:

Tasha assembled a picture frame that is advertised as rectangular. The completed frame is 14 inches long and 10 inches wide. She measured the diagonal length across the frame as 20 inches. Which best explains why the frame cannot actually be rectangular?
14 squared + 10 squared not-equals 20 squared
14 + 10 not-equals 20
(14 + 10) squared not-equals 20 squared
(14 squared + 10 squared) squared not-equals 20 squared
Answer:
a
Step-by-step explanation:
got it right
14 squared + 10 squared not-equals 20 squared. Therefore, option A is the correct answer.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given that, the completed frame is 14 inches long and 10 inches wide.
Tasha measured the diagonal length across the frame as 20 inches.
By using Pythagoras theorem, we have
20²=10²+14²
400=100+196
400≠296
Therefore, option A is the correct answer.

Step-by-step explanation:
3 times a number = 3n
is at least = greater than or equal to, so [tex]\geq[/tex]
that number plus 1 = n + 1
the same variable is used (n) because the number is supposed to be the same.

An online furniture store sells chairs for $200 each and tables for $600 each. Every
day, the store can ship a maximum of 32 pieces of furniture and must sell no less than
$12000 worth of chairs and tables. If 13 chairs were sold, determine the minimum
number of tables that the the store must sell in order to meet the requirements. If
there are no possible solutions, submit an empty answer.
Answer:
Step-by-step explanation:
Answer:
If the minimum 13 chair were sold , then the minimum number of Table sold is 14
Step-by-step explanation:
Given as :
The cost of each chair = $ 200
The cost of each table = $ 600
The total number of furniture sold per day = 32
The minimum amount of selling per day = $ 12000
Let the total number of chair = C
The total number of table = T
So , according to question
C + T = 32 .......1
200 C + 600 T = 12000 .......2
Solving eq 1 and 2
200 C + 600 T = 12000
200 × ( C + T ) = 32 × 200
I.e 200 C + 200 T = 6400
or, ( 200 C + 600 T ) - ( 200 C + 200 T ) = 12,000 - 6400
Or, 400 T = 5600
∴ T =
I.e T = 14
Put The value of T in eq 2
So, 200 C + 600 × 14 = 12000
or , 200 C + 8400 = 12,000
Or, 200 C = 12000 - 8400
Or, 200 C = 3600
∴ C =
I.e C = 18
The number of chair sold is 18
If the number of chair sold is 13 ,
Then the min number of table sold = 200 × 18 + 600 T = 12000
i.e 600 T = 12000 - 3600
or, 600 T = 8400
∴ T =
I.e T = 14
Hence if the minimum 13 chair were sold , then the minimum number of Table sold is 14 . Answer

cuál es el porcentaje de descuento de 70 a 45
Answer:
no habla espanol, sorry
Answer:
Utilizando la fórmula 2 y sustituyendo los valores indicados:
Precio de venta = Precio original - Valor del descuento. Así,
Precio de venta = 45 - 31.5
Precio de venta = $13.5 (respuesta)
Esto significa que el costo del artículo para usted es $13.5.
Usted pagará $13.5 por un artículo cuyo precio original fue $45 con un descuento de 70%.
En otras palabras, si usted compra una mercancía por $45 con 70% de descuento, Usted pagará $(45 - 31.5) = $13.5

Which is the sum of 8 3/4 +2 1/2?
O A. 11 1/6
B. 11 1/4
O C. 10 1/2
O D. 10 1/4
please help fast
Answer:
B. 11 1/4
Step-by-step explanation:
8 3/4 + 2 2/4 = 11 1/4
We want to sum two mixed numbers.
The correct option is D: 11 1/4
A mixed number is a number that is separated into a whole part and a rational part.
Here we want to sum:
(8 3/4) + (2 1/2)
This can be written as:
8 + 3/4 + 2 + 1/2
Now we group the whole numbers and we group the rational numbers:
8 + 3/4 + 2 + 1/2 = (8 + 2) + (3/4 + 1/2) = 10 + (3/4 + 1/2).
To perform the sum of the rational numbers, we can write:
1/2 = 2/4
Then we have:
10 + (3/4 + 1/2) = 10 + (3/4 + 2/4) = 10 + 5/4 = 10 + 4/4 + 1/4 = 11 + 1/4
Then we can see that the correct option is D.

1 mile = 1,760 yards
A) 4,400 yards
B) 3,520
C) 1,763 yards
D) 704 yards
Answer:
A) 4,400 Yards
Step-by-step explanation:
First, I added 1,760 + 1,760 together to represent 2 miles, and you get 3,520. Then, because it is a half mile you cut 1,760 in half to get 880. Finally, just add 3,520 + 880, which equals 4,400. I hope this helps :)

Step-by-step explanation:
Reflection over the y-axis:
When we reflect a point (x,y) over the y-axis, it's y-coordinate is kept, while the x-coordinate changes signal. So
(3,-1) -> (-3,-1)
Clockwise rotation of 180º
Both coordinates of the point change signals. So

A research group is interested in gauging perceptions about costs of textbooks among college students. They use an alphabetized list of students in state universities and use technology to generate a randomly shuffled list of students. They then select students to contact from this list until they have succeeded in contacting 175 students. What is the population parameter of interest
Answer:
Cost of textbooks
Step-by-step explanation:
The population parameter refers to any numerical messure derived from using the entire population data. Since the study above looks to evaluate how college students view the cost of books. Since the population of interest is all students, the reason for which the entire population of students are employed and the variable that is to be measured using these population of student is called the population parameter. In the other hand, numeric estimates or observations derived from a portion of the population called the sample is refereed statistic.
