Carmella simplified the following rational expression. (2x ^ 2 + 7x + 3)/(4x + 12) = ((2x + 1)(x + 3))/(4(x + 3)) = ((2x + 1)(x + 3))/(4(x + 3)) = (2x + 1)/4 After simplifying the expression , she stated that there are no restrictions on x since the denominator of her answer is a constant and cannot possibly equal Did Carmella make any mistakes in her problem ? If explain and correct her mistake ( s ) .

Answer:

w = -z(-w) + 3(-w)

Step-by-step explanation:

z = w + 3 | Given

-w + z = 3 | Subtract w from both sides.

-w = -z + 3 | Subtract z from both sides

w = -z(-w) + 3(-w) | Multiply -w on both sides.

Answer:

Total points scored by all together = 290 points.

Aaron and Nick wins.

Step-by-step explanation:

As given,

Total point scored by Noah and Luke = 135 points

Total point scored by Aaron and Nick = 160 points

Now,

Total points scored by all together = Total point scored by Noah and Luke +                                                                                  Total point scored by Aaron and Nick

⇒Total points scored by all together = 135 + 160 = 290 points.

As ,

160 > 135

⇒Total point scored by Aaron and Nick > Total point scored by Noah and Luke

∴ we get

Aaron and Nick wins.

Step-by-step explanation:

a x^2/4

b -x^2/4+3

c 4x^2

d -x^2

Answer:

1/4

Step-by-step explanation:

For a die,

the number of possible results is 6

The prime numbers are 2,3,5

the probability of getting a prime number is thus; 3/6 = 1/2

Tossing a coin, the probability of getting a head is also 1/2

So the probability of getting both on a single toss will be;

1/2 * 1/2 = 1/4

According to the question,

The number of possible results,

Prime numbers,

Now,

The probability of getting a prime number will be:

= [tex]\frac{3}{6}[/tex]

= [tex]\frac{1}{2}[/tex]

then, by tossing the coin head's probability is "[tex]\frac{1}{2}[/tex]".

hence,

Getting both on single toss will be:

= [tex]\frac{1}{2}\times \frac{1}{2}[/tex]

= [tex]\frac{1}{4}[/tex]

Thus the above answer is right.

Answer:

5. X = 2, Y = 3

6. X = 3, Y = 8

Step-by-step explanation:

For 5, it is easier to use the substitution method to solve. Plug the Y equation into the Y value of the first equation and simplify.

-3x - 2(5x-7) = -12

-3x - 10x + 14 = -12

-13 = -26x

x = 2

Then, plug the X value into either equation.

y = 5(2) -7

y = 3

For 6, it is easier to use the elimination method to solve. Multiply the first equation by 2 in order to eliminate 4y.

10x - 4y = -2

x + 4y = 35

Add these equations and simplify.

11x = 33

x = 3

Then, plug the X value into either equation.

3 + 4y = 35

32 = 4y

y = 8

Answer:

6 bowls of ramen eaten by you & your friend

Step-by-step explanation:

The question appears pretty choppy for me. I'll answer what I think you're asking and update in the comments if needed.

Imagine that you and a friend go to a local ramen shop for dinner at this restaurant, each regular bowl of ramen is $7.25. Drinks are $1.50 each. How many regular bowls of ramen did you and your friend eat if you ordered 2 drinks each and your total was $49.50?

a. Write an equation to represent the situation using x to represent the # of bowls you and your friend ate.

4($1.50) + $7.25x = $49.50

6 + 7.25x = 49.50

subtract 6 from both sides

7.25x = 43.50

divide both sides by 7.25

x = 6

Checking the math:

4(1.5) + 6(7.25) = 6 + 43.50 = 49.50

4 drinks, 6 bowls of ramen for $49.50

Step-by-step explanation:

Because we know Jordan already has $60, and he makes $6 per week, allwe have to do is multiply 6 times the number of weeks he is saving, which is also 6. That comes out to 36, so he saves $36 in 6 weeks, but we are tyring to find the total amount, so we add 36 and 60 to get 96.

Therefore, Jordan saves $96 after 6 weeks.

The next part of the questions asks for an expression. In the expression, w represents the amount of weeks. So, since he already had the $60, the expression would be:

60 + 6w

Step-by-step explanation: 10x-5 and 12x-26 are equal, as shown by the marks on their lines, so we can set them equal to each other to solve for x. when solved x=7. then plug 7 into each equation to get 65. lastly add up 84+65+65 to get 214.

Answer:

sqrt(x)=x^1/2

Step-by-step explanation:

The root of a number is the same as writing that number to 1 over the root. In a square root, it is what number multiplied by itself (x*x), as you can see there are two, so it is that number to the 1/2 power. another example is something to the seventh power. that is calculating what number multiplied by itself 7 times would equal the nmber you are taking the root of. (x*x*x*x*x*x*x) so this would be a number to the 1/7 power.
