Answer:

D. ; each drink cost $3

Step-by-step explanation:

Given that Elizabeth bought 4 drinks and some nachos.

Total amount spent = 18$

She can buy only in integers the drinks i.e.1,2,or 3

Nachos also she can buy 1,2...

If x is the no of nachos and d the cost of drink, we get

6x+4d=18

If x=1, d =3

x=2, d = 1.50

d=3, d=0 (which is not possible)

Hence d can take values either as 3 or 1.50

Out of the options given 3 is only there.

D. ; each drink cost $3

ALGEBRA TWO HELP!!!!!!!!!!!!
ohaa [14]

Answer:

\frac{p^{-4}q^{5}r^{6}}{p^{-3}qr^{-2}}=p^{-1}q^{4}r^{8}

Step-by-step explanation:

In division of powers with the same base, we must subtract the exponent of the denominator from the exponent of the numerator:

\frac{a^{m}}{a^{n}}=a^{m-n}

Then applying this to the problem:

\frac{p^{-4}q^{5}r^{6}}{p^{-3}qr^{-2}}=p^{-4-(-3)}q^{5-1}r^{6-(-2)}

Eliminating the parentheses:

\frac{p^{-4}q^{5}r^{6}}{p^{-3}qr^{-2}}=p^{-4+3}q^{5-1}r^{6+2}\\ \frac{p^{-4}q^{5}r^{6}}{p^{-3}qr^{-2}}=p^{-1}q^{4}r^{8}

How did you compute sums of dollar amounts that were not whole numbers?
soldier1979 [14.2K]

Answer:

$7.34

Step-by-step explanation:

To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :

$5.89 + $1.45

Taking the whole numbers first:

$5 + $1 = $6

Take the sum of the decimals :

$0.89 + $0.45 = $1.34

Sum initial whole + whole of sum of decimal

$6 + $1 = $7

Remaining decimal : $1.34 - $1 = $0.34

$7 + $0.34 = $7.34
