What is (2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)

zhenek [66]

Answer:

-20.2m -11.8

Step-by-step explanation:

(2y + 14.6m + 3.8) – (34.8m + 15.6 + 2y)

Distribute the minus sign

(2y + 14.6m + 3.8) – 34.8m - 15.6 - 2y

I like to line them up vertically

2y + 14.6m + 3.8

– 2y -34.8m - 15.6

------------------------------

-20.2m -11.8

Identify the sequence as arithmetic, geometric, both, or neither. 50, –50, 50, –50, . . . both arithmetic geometric neither desc

stellarik [79]

Answer:

The sequence is geometric.

Step-by-step explanation:

In Arithmetic sequence, there is a common difference between any two consecutive terms but in Geometric sequence, there is a common ratio between any two consecutive terms.

Given sequence is: 50, -50, 50, -50,.................

Lets assume, the terms as $a_{1}, a_{2}, a_{3}, a_{4},...........$

Checking for common difference:

$a_{2}-a_{1}= (-50)-(50)= -100\\ \\ a_{3}-a_{2}=(50)-(-50)=100\\ \\ a_{4}-a_{3}=(-50)-(50)=-100$

As there is no common difference, so it's not an arithmetic sequence.

Checking for common ratio

$\frac{a_{2}}{a_{1}}=\frac{-50}{50}=-1\\ \\ \frac{a_{3}}{a_{2}}=\frac{50}{-50}=-1\\ \\ \frac{a_{4}}{a_{3}}=\frac{-50}{50}=-1$

As there is a common ratio, so it's a geometric sequence.

One serving of chicken has 148 grams of protein, which is 80% of the recommended daily amount.

valentinak56 [21]

Answer:

x = 185 grams

Step-by-step explanation:

let 100% of the recommended daily amount = x

148 = 80%x

148 = 0.8x

divide by 0.8 both sides

x = 185
