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

Answer:

The maximum number of packages that can be made with each package have same number of each item is = 6

Step-by-step explanation:

Given:

Mr. Harris has 48 pencils and 30 notebooks.

To find the number of packages he can make with each package have same number of each item.

Solution:

Number of pencils = 48

Number of notebooks = 30

In order to find the number of packages he can make with each package have same number of each item, we will find the greatest common factor of the given numbers.

<em>To find the G.C.F., we will list down the prime factors of each.</em>

$48=2\times 2\times 2\times 2\times 3$

$30=2\times 3\times 5$

We find that the G.C.F. = $2\times 3$ = 6

Thus, the maximum number of packages that can be made with each package have same number of each item is = 6

Someone plz help me!

Verdich [7]

Answer:

56.25 cm

Step-by-step explanation:

your teacher wrote the approach already : the law of sines.

in our example we have

sin(28)/27 = sin(102)/c

c×sin(28)/27 = sin(102)

c×sin(28) = 27×sin(102)

c = 27×sin(102)/sin(28) = 27×0.98/0.47 = 56.25 cm
