Answer:

w>-12

Step-by-step explanation:

6>w/-2 (Given)

6>-w/2 (Rewrite)

12>-w (Multiply both sides by 2)

-12<w (Remember to flip the sign when dividing or mulitplying by a negative)

w>-12 (Rewrite with w in front)

Therefore, w>-12 is the solution to the inequality.

Answer:

w>-12

Step-by-step explanation:

First, you you need to get rid of the -2 in w/-2 by multiplying -2 by both sides like this.

(-2)6>w/-2(-2)

Then you simplify it like this:

-12>w

However, since you multiplied/divided with a negative, you switch the inequality sign like this:

w>-12

And that's the answer!

A small box of cereal contains 10 cups of cereal. A medium box of the same cereal contains 30% more cereal than the small box. H

Answer:

13 cups

Step-by-step explanation:

If the small box has 10 cups, then:

(small) 10 cups = 100%

(medium) x cups = 130%

Now, cross multiply:

10 (130) = x (100)

1300 = 100x

x = 13

Another way to solve this is by turning 30% into a decimal:

30/100 = 0.3

10 (0.3) = 3

Now you have 30% of the 10 cups, but you need 30% more than the small box, so:

10 + 3 = 13 cups

Answer:

k=-3

Step-by-step explanation:

Equation of a line

The general equation of a line can be written as:

Ax+By=C

The x-intercept is the point where the line crosses the x-axis, i.e. y=0, thus replacing x=3 and y=0:

A(3)+B(0)=C

3A=C

Solving for A:

A=C/3

The y-intercept is the point where the line crosses the y-axis, i.e. x=0, thus replacing x=0 and y=5:

A(0)+B(5)=C

5B=C

Solving for B:

B=C/5

Replacing into the general equation:

$\displaystyle \frac{C}{3}x+\frac{C}{5}y=C$

Simplifying by C:

$\displaystyle \frac{x}{3}+\frac{y}{5}=1$

The point P(k,10) belongs to the line, thus:

$\displaystyle \frac{k}{3}+\frac{10}{5}=1$

Operating:

$\displaystyle \frac{k}{3}+2=1$

$\displaystyle \frac{k}{3}=-1$

Multiplying by 3:

$\boxed{k=-3}$
