Answer:

$\frac{13}{8}$

Step-by-step explanation:

$\frac{13}{8} \: \: cuz \: when \: u \: simplify \: into \: a \: decimal \: would \: be \: 1.625 \\ and \: if \: u \: round \: would \: be \: 2 \: so \: u \: take \: out \: the \: decimal \:$

Need help simplifying this

diamong [38]

The simplified answer is $\frac{\left(12 x^{2}+7 x y-4 y z-3 x z+3 y^{2}\right)}{6 x^{2}+3 x z+2 x y+y z}$ .

<u>Step-by-step explanation:</u>

$$\frac{3 y+2 x}{z+2 x}-\frac{2 y-3 x}{3 x+y}-\frac{2 z(y+3 x)}{6 x^{2}+3 x z+2 x y+y z}$

To add or subtract denominators of the fraction must be same.

If it is not the same, we must take LCM of the denominators. and so we can add the fractions.

To make the denominator same multiply the 1st term $(\frac{3x+y}{3x+y})$ and 2nd term by $(\frac{z+2x}{z+2x})$

= $\frac{(3 y+2 x)(3 x+y)}{(z+2 x)(3 x+y)}-\frac{(2 y-3 x)(z+2 x)}{(3 x+y)(z+2 x)}-\frac{2 z(y+3 x)}{6 x^{2}+3 x z+2 x y+y z}$

LCM of the denominators is 6x²+ 3xz + 2xy +yz.

Multiply the factors in the numerator.

= $\frac{\left(6 x^{2}+3 y^{2}+11 x y\right)}{(z+2 x)(3 x+y)}-\frac{\left(2 y z+4 x y-3 x z-6 x^{2}\right)}{(3 x+y)(z+2 x)}-\frac{2 z y+6 x z}{6 x^{2}+3 x z+2 x y+y z}$

Now, the denominators are same, you can subtract it.

= $\frac{\left(6 x^{2}+6 x^{2}+11 x y-4 x y-2 y z-2 y z+3 x z-6 x z+3 y^{2}\right)}{6 x^{2}+3 x z+2 x y+y z}$

= $\frac{\left(12 x^{2}+7 x y-4 y z-3 x z+3 y^{2}\right)}{6 x^{2}+3 x z+2 x y+y z}$

Thus the simplified solution is $\frac{\left(12 x^{2}+7 x y-4 y z-3 x z+3 y^{2}\right)}{6 x^{2}+3 x z+2 x y+y z}$

Solve each of these equations. Explain or show your reasoning. 2(3x+2)=2x+28 5y+13=-43−3y 4(2a+2)=8(2−3a)

dalvyx [7]

Answer:

x = 6

y = 7

a = 1/4

Step-by-step explanation:

Equation 1:

2(3x+2) = 2x + 28

6x + 4 = 2x + 28

4x = 24

x = 6

Equation 2:

5y+13 = -43-3y

8y = -56

y = -7

Equation 3:

8a + 8 = 16 - 24a

32a = 8

a = 1/4

This equation shows how the total number of appetizer recipes Emily knows depends on the number of weeks she attends culinary sc

Alexxandr [17]

Answer:

W=2

Step-by-step explanation:

First you have to fill A in as 19 because thats how many culinary recipes that she will need to know

Second you then have to get the variable W by itself so you would subtract 17 from the side that W is on

Once you subtract 17 from one side you have to subtract from the other

So therefore W would =2
