Answer:
Step-by-step explanation:
If you look at it this way, one can say that algebra does act as a tool to improve communication in the sense that, it is similar, in a way, to learning a new language. You don't rush into it, you start rather gently, little by little, step by step before you can say, you fully get it. We can then agree that this will improve one's communication prowess because the person would be learning something new with the help of some other people.
Answer:
B)-1/4
Step-by-step explanation:
f(x) = 4x ; slope is 4
perpendicular , slope is opposite and reciprocals so slope of this perpendicular line is -1/4

Answer: £17.20</h3>
=====================================================
Explanation:
x is some positive number such that the earnings of Paul, Collin, and Brian are 2x, 3x and 4x in that order
The ratio 2x:3x:4x reduces to 2:3:4 when we divide all parts by x
The total amount of tips was 77.40 pounds
This means,
(Paul's Share)+(Collin's Share)+(Brian's Share) = Total Tips
(2x)+(3x)+(4x) = 77.40
9x = 77.40
x = 77.40/9
x = 8.6
Use that x value to find each of their share of tips
- Paul's Share = 2x = 2*8.6 = 17.20 pounds
- Collin's Share = 3x = 3*8.6 = 25.80 pounds
- Brian's Share = 4x = 4*8.6 = 34.40 pounds
As a check, note how 17.20+25.80+34.40 = 77.40
The last step is to subtract the values for Brian and Paul
34.40 - 17.20 = 17.20
Brian earned £17.20 more in tips compared to Paul.
50+5+2 or is there a certain type of number are you looking for?
Answer:
Lets do this by first finding how many miles the sub will descend in 1 min, and we can do that as shown below,
In 1 minute the submarine go: -56/4
⇒-14/1
Thus in one minute itself the submarine wil go -14 miles from the sea level
The simplest form is given above, other than that we can also use -28/2 but it wont be in simplest from so it will be better to give the first one.
