Lian has $1.00. She has only nickels and dimes. Lian has twice as many dimes as nickels. How many dimes does she have?

Anna11 [10]

Answer: 8

Step-by-step explanation:

Given

Lian has $\$1.00$ and she has twice as many dimes as nickels

Suppose she has $x$ nickels

So, the number of dimes is $2x$

Nickel is equivalent to 5 cents and dime is equivalent to 10 cent

$\therefore \ x(0.05)+2x(0.1)=1\\\Rightarrow 0.05x+0.2x=1\\\Rightarrow 0.25x=1\\\Rightarrow x=4$

Therefore she has 8 dimes with her.

Please help me <br>find f(x+h)

Kay [80]

Answer:

f(x) = -2x+5

f(x+h) = -2x -2h +5

g(x) = -4x-2

g(x+h) = -4x -4h -2

h(x) = 4x^2+1

h(x+h) = 4(x+h)^2 +1 = 4x^2 +8xh + 4h^2 +1

Q(x) = -3x^2 +4

Q(x+h) = -3(x+h)^2 +4 = -3x^2 -3h^2 -6xh + 4
