Simply divide the number by 3. Therefor splitting it into 3 and calculating the value of each section. By dividing by 3 you get an instant answer as to what a 3rd of it’s value is. Think 1/3rd of 9, now imagine evening distributing 9 marbles in 3 cups. You’ve just divided 9 by 3. The number in any of the cups is the same. That’s what dividing (generic division at least) does. It tells you what would be in each cup.

Answer: no

Step-by-step explanation: to change a fraction back to a improper fraction

multiply the whole number by the denominator and then add it to the numerator but be careful with negative. You can check this process by changing the improper fraction back to proper. If i change -17/10 i get -1 7/10. the correct answer is -23/10.

Can someone explain and answer please??

Simplify the ration expression
$\frac{3x-6}{x-2}$

start by seeing if anything in the numerator or denominator can be factored,
you should notice that you can factor out a 3 from 3x-6 in the numerator

when you do so, the result is
$\frac{3 *(x-2)}{x-2}$

now, since there is an x-2 in the numerator and denominator, they "cancel" out since

$\frac{x-2}{x-2} =1$
however, only when $x \neq 2$
since $\frac{0}{0} \neq 1$

when you cancel out the x-2, you're left with 3

hence, your answer is C

Penelope determined the solutions of the quadratic function by completing the square. F(x) = 4x2 8x 1 –1 = 4x2 8x –1 = 4(x2 2x)

By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.

<h3>What is quadratic equation ?</h3>

Any equation of the form $ax^2+bx+c=0$ where x is variable and a, b, and c are any real numbers where a ≠ 0 is called quadratic equation .

Given work of Penelope is

$\begin{aligned}&f(x)=4 x^{2}+8 x+1 \\&-1=4 x^{2}+8 x \\&-1=4\left(x^{2}+2 x\right) \\&-1+1=4\left(x^{2}+2 x+1\right) \\&0=4(x+2)^{2} \\&0=(x+2)^{2} \\&0=x+2 \\&-2=x\end{aligned}$

Now we can see that Penelope determined the solutions of the quadratic function by completing the square. so he must have been done as following

$\begin{aligned}&f(x)=4 x^{2}+8 x+1 \\&-1=4 x^{2}+8 x \\&-1=4\left(x^{2}+2 x\right) \\&-1+4=4\left(x^{2}+2 x+1\right) \\&3=4(x+2)^{2} \\&\frac{3}{4} =x+2)^{2} \\&\frac{\pm\sqrt3}{2} =x+2 \\&\frac{-2\pm\sqrt3}{2} =x\end{aligned}$

By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.

#19 is the question. i’m stuck on it, i missed the class where we went over it. please help!!

Step-by-step explanation:

Since the powers are equal you can write the expression as a one root

But we cannot get 9 out since the square root of 9 is 3 which is second power (3^2) and the power of the root is 4

Holpe this helps, if you need further explanation you can ask.
