Answer:
6,000
Step-by-step explanation:
Answer:
The amount invested in the mutual fund that earned 5% was $1,000
The amount invested in the mutual fund that earned 3% was $1,800
Step-by-step explanation:
Let
x ----> the amount invested in the mutual fund that earned 5%
y ----> the amount invested in the mutual fund that earned 3%
we know that
----> 
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B
Solve for x
<em>Find the value of y</em>
therefore
The amount invested in the mutual fund that earned 5% was $1,000 and the amount invested in the mutual fund that earned 3% was $1,800
Answer: 22.5 . The weight of the elephant is "22.5 times greater" than the weight of the lion.
_________________________________________________________
Explanation:
_________________________________________________________
(weight of lion) * (x) = (eight of the elephant) ; Solve for "x" .
_____________________________________________________
→ Divide each side of the equation by "(weight of lion)" ;
to isolate "x" on one side of the equation ; and to solve for "x" ;
_________________________________________________________
→ (weight of lion)*(x) / (weight of lion) = (weight of the elephant) /
(weight of lion) ;
________________________________________________________
→ x = (weight of the elephant) / (weight of lion) ;
__________________________________________________________
→ Plug in our "given values" ; and solve for "x" ;
__________________________________________________________
→ x = (<span>9*10</span>³) / (4*10²) = (9*10⁽³⁻²⁾) / 4 = (9*10¹) / 4 ;
__________________________________________________________
→ x = 90 /4 = 25/2 = 22.5 ; which is our answer.
