1.1 Pull out like factors :

-8x - 2 = -2 • (4x + 1)

2.1 Divide both sides by -2

Remember to flip the inequality sign:

2.2 Divide both sides by 4

x+(1/4) ≥ 0

Solve Basic Inequality :

2.3 Subtract 1/4 from both sides

x ≥ -1/4

Answer:

The answer is D.

Step-by-step explanation:

Divide both sides by -8 to get x by itself.

-8x ≤ 2

-8x/-8 = x

2/-8 = -0.25

What you're left with is x ≤ -.25

Since you divided you have to switch the signs.

x ≥ -.25

Divide a24 - a18 + a12 by a6.

AnnZ [28]

24a-18a+12a is equal to 18a
hence, divide it by 6a
so you get 3a :)

What's the surface area ratio & the volume ratio??<br><br> please help me ASAP!!

Ulleksa [173]

Answer:

Step-by-step explanation:

Volumes of two spheres A and B = 648 cm³ and 1029 cm³

Things to remember:

1). Scale factor of two objects = $\frac{r_1}{r_2}$ [ $r_1$ and $r_2$ are the radii of two circles]

2). Area scale factor = $\frac{(r_1)^2}{(r_2)^2}$

3). Volume scale factor = $\frac{(r_1)^3}{(r_2)^3}$

Volume scale factor Or Volume ratio = $\frac{V_A}{V_B}$

$\frac{(r_1)^3}{(r_2)^3}= \frac{648}{1029}$

$\frac{r_1}{r_2}=\sqrt[3]{\frac{648}{1029} }$

$\frac{r_1}{r_2}=\frac{6(\sqrt[3]{3})}{7(\sqrt[3]{3})}$

$\frac{r_1}{r_2}=\frac{6}{7}$

Therefore, scale factor = $\frac{r_1}{r_2}=\frac{6}{7}$

≈ 6 : 7

Area scale factor Or area ratio = $(\frac{r_1}{r_2})^2=(\frac{6}{7})^2$

= $\frac{36}{49}$

≈ 36 : 49

Volume scale factor or Volume ratio = $\frac{648}{1029}$

= $\frac{216}{343}$

≈ 216 : 343

ale4655 [162]

Answer:

The system that can be used is:

$10x + 2y = 56$

$9x + 3y = 60$

Step-by-step explanation:

We have that:

x is the price of a package of sugar cookies, y is the price of a package of oatmeal cookies.

Shaikha sold 10 packages of sugar cookies and 2 packages of oatmeal cookies for $56.

This means that:

$10x + 2y = 56$

Khalid sold 9 packages of sugar cookies and 3 packages of oatmeal cookies for $60.

This means that $9x + 3y = 60$

System that can be used:

The system that can be used is:

$10x + 2y = 56$

$9x + 3y = 60$
