Whats the next two terms in order are p+q, p , p-q

Law Incorporation [45]

Answer:

p - 2q and p - 3q

Step-by-step explanation:

A Series is given to us and we need to find the next two terms of the series . The given series to us is ,

$\rm\implies Series = p+q , p , p - q$

Note that when we subtract the consecutive terms we get the common difference as "-q" .

$\rm\implies Common\ Difference = p - (p + q )= p - p - q =\boxed{\rm q}$

Therefore the series is Arithmetic Series .

Arithmetic Series:- The series in which a common number is added to obtain the next term of series .

And here the Common difference is -q .

Fourth term :-

$\rm\implies 4th \ term = p - q - q = \boxed{\blue{\rm p - 2q}}$

Fifth term :-

$\rm\implies 4th \ term = p - 2q - q = \boxed{\blue{\rm p - 3q}}$

Therefore the next two terms are ( p - 2q) and ( p - 3q ) .

amm1812

Answer:

C) 20 hours

Step-by-step explanation:

x = number of hours

A yard cleanup service charges a $380 fee plus $14 per hour.

380 + 14x

Another cleanup service charges a $260 fee plus $20 per hour.

260 + 20x

How long is a job for which the two companies' costs are the same?

380 + 14x = 260 + 20x

380 - 260 = 20x - 14x

120 = 6x

20 = x

How many gallons each of 0.5% milk and 3% milk should a dairy farmer combine to

Umnica [9.8K]

Answer:

2.8 gallons 0.5% milk

4.2 gallons 3% milk

Step-by-step explanation:

let 'x' = .5% milk

let 'y' = 3% milk

System of Equations:

x + y = 7

.005x + .03y = 7(.02)

I used the substitution method and solved the first equation for y: y = 7 - x

.005x + .03(7 - x) = .14

.005x + 0.21 - .03x = 0.14

-0.025x + 0.21 = 0.14

-0.025x = -0.07

x = 2.8

7 - 2.8 = 4.2

y = 4.2
