You have to divide the number by the denominator of the fraction. For example, if you want to find 1/5 of 20, you have to divide 20 by 5 and that tells you that 1/5 of 20 is 4.
Perimeter=4*side so
side=p/4 and we are told p=16x+32y so
s=(16x+32y)/4
s=4x+8y
s=4(x+2y)
Answer:
4(x-7)^2-(x-7)+3 (Assuming t is f)
Step-by-step explanation:
Let s(x)=x-7 and t(x)=4x^2-x+3 .
(t o s)(x)=t(s(x))=t(x-7)
Before I continue this means replace the orginal x in t with x-7.
This will then give you
4(x-7)^2-(x-7)+3
Answer:
The total cost is D) $141
Step-by-step explanation:
To solve we can use the equation: 
d= number of days m= number of miles
We know both of these values so we can plug them in and solve.
y= 25(3) + 0.10(660)
y= 75 + 66
y = 141
Answer:
$100,700
Step-by-step explanation:
Given data
Principal= $38,000
rate= 8.25%
Time= 20 years
Applying the simple interest
A=P(1+rt)
substitute
A=38000(1+0.0825*20)
A=38000(1+1.65)
A=38000*(2.65)
A=$100,700
Hence in 20 years she will pay $100,700
