Answer:
300
Step-by-step explanation:
d= dimes
n = nickels
d =n+7
n*.05+.1*d = 1.90
substitute d = n+7
.05n +.1 (n+7) = 1.9
distribute
.05n +.1n +.7 = 1.90
combine like terms
.15n +.7 = 1.9
subtract .7 from each side
.15n = 1.2
divide by .15
n=8
d=n+7
d=15
you have 8 nickels and 15 dimes

Answer:
x = 8√2 units
Step-by-step explanation:
On a 45-45-90 triangle,<em> the ratio between one of the legs </em>(both are congruent)<em> and the hypotenuse is 1 : √2</em> (Improper but it still sends the message). That means the hypotenuse is √2 times as long as a leg.
x = 8 × √2
x = 8√2 units
