Answer:

A. Parentheses.

Step-by-step explanation:

We are asked to find the operation that should be performed first for calculations involving more than one arithmetic operation.

We use order of operations (PEMDAS) to solve a problem involving more than one arithmetic operation.

P = Parenthesis,

E = Exponent,

M/D = Multiplication or Division (Left to right)

A/S = Addition or subtraction (Left to right)

Therefore, we should remove parenthesis first in calculations involving more than one arithmetic operation.

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 ) .

Y = f(x) + 3 describe the functions that take place

hram777 [196]

Answer:

A function can be reflected about an axis by multiplying by negative one. To reflect about the y-axis, multiply every x by -1 to get -x. To reflect about the x-axis, multiply f(x) by -1 to get -f(x).

The amount of water in a bottle is reduced by 15% to 119 milliliters. How much water was originally in the bottle? ________ ml

lakkis [162]

Answer: 140 ml

Explanation:

let x be the original amount of water

x - 15% = 119
But x = 100% because it’s the original
=> 100% - 15% = 119ml
85% = 119ml

Find the amount of water in 15%:
85% = 119
15% = y

=> 85/15 = 119/y

Cross multiply:
85y = 15 x 119
85y = 1785
y = 1785/85
y = 21

But y = 15% therefore, 15% = 21ml

Back to our equation:
x - 15% = 119ml
x - 21ml = 119ml
x = (119 + 21)ml
x = 140ml

Therefore, the original amount of water is 140ml
