The first thing we must do for this case is to define variables.
We have then:
x = cost of a hardcover book
y = cost of a paperback book
We write the system of equations:
3x + 7y = 29.50
2x + 5y = 20.50
The solution to the system is:
x = 4 $
y = 2.5 $
Answer:
the cost of a hardcover book is $ 4

Answer:
Step-by-step explanation:
- Estimated height is 4 feet
- Measured height is 4 feet 2 inches
1. The measurement is actual and should be considered as such. Estimate is approximate most of the time.
2. <u>The error is:</u>
- 4 feet 2 inches - 4 feet = 2 inches
3. <u>Percent error:</u>
- 2 inches/4 feet 2 inches × 100% =
- 2 inches / 50 inches × 100% =
- 0.04× 100% =
- 4%
Answer:
Weight on the moon=x=15.87 kilograms
Step-by-step explanation:
This can be expressed as;
Weight on earth=Constant×Weight on moon
where;
Weight on moon=14.2 kilograms
Constant=k
Weight on Earth=85 kilograms
Replacing in the expression above;
85=14.2×k
k=(85/14.2)=5.986
If the person weighs 95 kilograms on Earth;
Weight on the earth=Constant×Weight on moon
where;
Weight on the moon=x
Constant=5.986
Weight on the earth=95 kilograms
Replacing;
95=5.986×x
x=95/5.986=15.87
Weight on the moon=x=15.87 kilograms
