Answer:

n = -4

Step-by-step explanation:

Notice how in the previous examples they all divide by 2? It is the same case here. So now the question is... "what" divided by "2" is "-2".

Let me show you:

n ÷ 2 = -2

if you know your integer math, you should know that...

-4 ÷2 = -2 (this is the correct equation)

ikadub [295]

For this case what you must do is the following rule of three:
50 ---> 100
80 ----> x
We clear x:
x = (80/50) * (100)
x = 160%
160-100 = 60%

nydimaria [60]

Answer:

In every 42 days, Sherman and Brad will go golfing on the same day.

Step-by-step explanation:

Given:

Sherman goes golfing every 6th day.

Brad goes golfing every 7th day.

If they both went golfing today, we need to determine how many days unit they will go golfing on the same day again.

Solution:

In order to determine how many days unit Sherman and Brad will go golfing on the same day again, we will take least common multiple of 6 and 7.

To find least common multiple of 6 and 7, we will list out their multiples.

$6=6,12,18,24,30,36,42$

$7=7,14,21,28,35,42$

We find out that the least common multiple of 6 and 7 =42.

Thus, we can conclude that Sherman and Brad will go golfing on same days on every 42nd day after they meet..

Preston's salary before taxes are taken out is p dollars. After taxes taken out, Preston's take home salary is t dollars. If p =

Karolina [17]

Answer:

$After\ Tax = \frac{p}{1.25}$

Step-by-step explanation:

Given:

$Before\ Tax =\$ p$

$After\ Tax =\$ t$

$p = 1.25t$

Required

Determine his after tax salary in terms of p

To do this, we simply make t the subject in $p = 1.25t$

Divide both sides by 1.25

$\frac{p}{1.25} = \frac{1.25t}{1.25}$

$\frac{p}{1.25} = t$

$t = \frac{p}{1.25}$

Substitute p/1.25 for t in $After\ Tax =\$ t$

$After\ Tax = \frac{p}{1.25}$
