Answer:
x = 52.5
Step-by-step explanation:
4x + 6(10) = 4.32(x + 10)
4x + 60 = 4.32x + 43.20
0.32x = 16.8
x= 52.5
The answer would be y=15x
Step-by-step explanation:
if y is equal to 15 times x then y=15x
Answer:
50 coins
Step-by-step explanation:
if there is 1/5 more 1 dollar coins than quarters that means 1/5 of the total number is equal to 10, and if 1/5 is 10 that means 5*10=50 is the total number
Hello,
ln(y)=ln(x^(ln(x))=ln(x)*ln(x)=(ln(x))²
(ln(y))'=2ln(x)*1/x
(1/y)*y'=2ln(x) / x
y'=(2 ln(x) * x^(ln(x)) ) /x
