You'll have to solve simultaneously
let nickel be x, dime be y
x + y = 35 ... ( 1 )
5x + 10 y = 250
5 ( x + 2y ) = 250
x + 2y = 50 ... ( 2 )
in ( 1 )
x = 35 - y ( 3 )
sub ( 3 ) into ( 2 )
( 35 - y ) + 2y = 50
y = 15
sub y into ( 1 )
x + y = 35
x + 15 = 35
x = 20
therefore, Sandy has 20 nickels and 15 dimes
Answer:
A and E
Step-by-step explanation:
A is already given by the basic fact that DE = FG. this makes the 2 lines automatically also congruent.
but this does not tell us anything about EF.
E and F could be very close together or far apart, and still DE = FG can be true in either case.
and that is why B, C and D could be true, but they are not in all cases true, and therefore these statements are in general false.
Answer:
ln6 = 1.79
Step-by-step explanation:
The logarithm here has base e so it is a natural logarithm.
According to the product rule of logarithms
∴ ln6 = 1.79
Answer:
$49.50
Step-by-step explanation:
You take the $45 and multiply it by 10% (tax). That comes out to $4.50. Then, you take the $45.00 (grocery bill) and add it to $4.50 (10% tax)
$45.00 + $4.50=$49.50
