Evaluate each expression if a = 4, b = 6, and c = 2
-> 3a +6²c
What is
Step-by-step explanation:
a=4 so 3a becomes 3x4.
3x4=12
12+6c^2
C=2 so 6c^2 becomes (6x2)^2
6x2=12 and 12x12 because of the exponent.
12x12=144
12+144=156

1. Numa escola de 670 alunos, 352 estudam Inglês, 125 fazem apenas o curso de Espanhol e 85 estudam as duas línguas. Com base nessas informações, determine: a) Quantos estudam Inglês ou Espanhol? b) Quantos fazem espanhol? c) Quantos não estudam nenhuma dessas línguas?
Answer:
a) Quantos estudam Inglês ou Espanhol?
477
b) Quantos fazem espanhol?
210
c) Quantos não estudam nenhuma dessas línguas?
193
Step-by-step explanation:
a) Quantos estudam Inglês ou Espanhol?
Inglês ou Espanhol = Quantidade de alunos que cursam inglês + Quantidade de alunos que cursam espanhol - Quantidade de alunos que cursam inglês e espanhol
= 352 + 210 - 85
= 477
b) Quantos fazem espanhol?
Isso é dado na pergunta como alunos que só aprendem espanhol = Somos informados de que o número de alunos que estudam apenas espanhol = 125
Número de alunos que cursam espanhol = Número de alunos que cursam apenas espanhol + Número de alunos que cursam espanhol e inglês
Número de alunos que fazem espanhol = 125 + 85
= 210 alunos
c) Quantos não estudam nenhuma dessas línguas?
Número total de alunos - (número de alunos que não cursam nenhum dos idiomas) = Número de alunos que cursam inglês + Número de alunos que cursam espanhol - Número de alunos que cursam os dois
= 670 - (número de alunos que não estudam nenhum dos idiomas) = 352 + 210 - 85
= 670 - (número de alunos que não estudam nenhum dos idiomas) = 477
Número de alunos que não cursam nenhum dos idiomas = 670 - 477
= 193 alunos

Answer:
x = 3x = - 5/3Step-by-step explanation:
2|3x - 2|= 14|3x - 2|= 71) 3x - 2 ≥ 0 ⇒ 3x ≥ 2 ⇒ x ≥ 2/3
3x - 2 = 73x = 9x = 3 is valid root as 3 ≥ 2/32) 3x - 2 < 0 ⇒ 3x < 2 ⇒ x < 2/3

Answer:
The total number of cups is 9 1/2 cups
Step-by-step explanation:
Here, we are interested in calculating the total cups of trail mix that Mr V can make.
From the question, we are told that he used 1/2 cups of peanuts, 2 1/4 cups of raisins and 2 times more sunflower seeds than raisins.
So basically, we need to find the number of cups of sunflower seeds used.
The information we have here is that he used 2 times more of raisins;
Thus, the number of cups of sunflower would be 2 * 2 1/4 = 2 * 9/4 = 9/2. But practically is 9/2 , two times more than 2 1/4? NO!
What we should do here is to add 9/2 to 2 1/4. In that case, the difference between the two will be 2 times the cups of raisins;
So 9/2 + 9/4 = (18 + 9)/4 = 27/4
So the total number of cups of trail mix that can be made will be;
1/2 + 27/4 + 9/4 = (2 + 27 + 9)/4 = 38/4 = 19/2 = 9 1/2 cups

7) A real number that is less than zero. These represent opposites.
Answer:
A negative number
Step-by-step explanation:
I know this is right. Negative numbers represent opposites. If positive represents a movement to the right, negative represents a movement to the left.In the context of negative numbers, a number that is greater than zero is referred to as positive. Thus every real number other than zero is either positive or negative, while zero itself is not considered to have a sign. Positive numbers are sometimes written with a plus sign in front, e.g. +3 denotes a positive three.
-12x + 18 – 10x – 5 = -31
Answer:
22
Step-by-step explanation:
Step 1:
- 12x + 18 - 10x - 5 = - 31
Step 2:
- 22x + 18 - 5 = -31
Step 3:
- 22x + 13 = - 31
Step 4:
- 22x = - 44
Answer:
x = 22
Hope This Helps :)
Answer:
Your answer is x = 2
Step-by-step explanation: [tex]-12x + 18-10x-5 = -31[/tex]
subtract 18 - 5 = 13 and add -12x+(-10x)= -22x
[tex]-22x+13=-31[/tex] subtract 13 on both sides
[tex]-22x+13(-13)=-31(-13)[/tex] cross out +13(-13) and -31-13= -44
[tex]-22x=-44[/tex] divide -22 on both sides
[tex]\frac{-22x}{-22} = \frac{-44}{-22}[/tex] cross -22x/-22 and divide -44 and -22= 2
[tex]x = 2[/tex]

Enter the numbers that belong.
Answer:
Here's your answer
hope this helped you
please mark as the brainliest (ㆁωㆁ)
Answer:
x = [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
Given
- 3 - 39x = 11x - 23 ( subtract 11x from both sides )
- 3 - 50x = - 23 ( add 3 to both sides )
- 50x = - 20 ( divide both sides by - 50 )
x = [tex]\frac{-20}{-50}[/tex] = [tex]\frac{2}{5}[/tex]

A point has the coordinates (0, k).
Which reflection of the point will produce an image at the same coordinates, (0, k)?
Answer:
B
Step-by-step explanation:
I took the assignmen.
The reflection of point that will produce the image at same coordinate (0, k) is across the y - axis
We have a Point with coordinates (0, k).
We have to find the reflection that will produce the image at the same coordinate (0, k).
Consider a Point P (x, y). Find the image of the point across x - axis and y - axis.For a Point P [tex](x,y)[/tex] the image across -
x - axis is (x, -y).y - axis is (-x, y)We can use the above laws to find the reflection of point
For Point P(0,k) , the -
image across x - axis will be (0, -k).image across y - axis will be (-0, k), which is same as (0, k).Hence, the reflection of point that will produce the image at same coordinate [tex](0,k)[/tex] is across the y - axis.

True or False, the chance of flipping heads on a coin 3 times in a row is 1/2
true flip a coin it's fifty fifty
Answer:
False
Step-by-step explanation:
Each toss is an independent event, so the probability of three tosses of heads in a row is the product of the three probabilities..
Each probability of heads is
p(heads) = 1/2
p(heads, heads, heads) = p(heads) * p(heads) * p(heads) = 1/2 * 1/2 * 1/2 = 1/8

Markus decides to return 4 shirts costing $19 each to a clothing store. While there, he decides to purchase 2 pairs of shoes at $45 each and a raincoat for $62.75. The clerk charges him 5% tax on the amount due after returns. What amount does he owe the clerk?
Answer:
$80.59
Step-by-step explanation:
You add the price of the raincoat and shoes to get 152.75, you then subtract the price of the 4 shirts you returned to get 76.75. The 5% tax for this is 3.84 so you add the two together and you get $80.59.
