(n+5)^2=48
sqrt both sides
n+4=+/-4√3
minus 4 both sides
n=-4+/-4√3
-4+4√3>0 so this cannot be the value of n
n=-4-4√3
the number is -4-4√3
Mom gave $ 320 to each girl
<u>Solution:</u>
Given that Lily and Elsa are both college students
Before mom gave them this months allowance lily had $750 and Elsa had &215
<em><u>So amount with Lily and Elsa already is:</u></em>
amount with Lily = $ 750
amount with Elsa = $ 215
After mom gave each girl an equal amount of money for this months allowance, lily had twice as much money as Elsa
Let "a" be the equal amount of money which mom gave to Lily and Elsa
<em><u>So now amount with Lily and Elsa after mom gave equal amount is:</u></em>
amount with Lily = amount with Lily already + a
amount with Lily = 750 + a
amount with Elsa = amount with Elsa already + a
amount with Elsa = 215 + a
<em><u>Now given that lily had twice as much money as Elsa</u></em>
Amount with lily = 2(amount with elsa)
750 + a = 2(215 + a)
750 + a = 430 + 2a
2a - a = 750 - 430
a = 320
Thus mom gave $ 320 to each girl
8 / 86 = 12 / x
cross multiply
(8)(x) = (86)(12)
8x = 1032
x = 1032/8
x = 129 pieces
Answer:
B
Step-by-step explanation:
Both of the two numbers should equal the same amount when dividing.
For example, in A
25÷15=1.666...
30÷18=1.666...
Both of these answers are the same so that means that 25/30 is equivalent to 15/18
When you're dividing B though, they don't equal the same amount
90÷15=6
105÷18= 5.833...
that means that 90/105 does NOT equal 15/18
good luck
