Question 1:
For this case, the first thing we must do is define variables.
We have then:
x: number of nickels
y: number of dimes
We write the system of equations that adapts to the problem.
We have then:
0.05x + 0.10y = 6.10
x + y = 67
Solving the system we have:
x = 12
y = 55
Answer:
there are 12 nickels
Question 2:
For this case, the first thing we must do is define variables.
We have then:
x: Allan's score
y: Dave's score
We write the system of equations that adapts to the problem.
We have then:
x + y = 375
x = 2y-60
Solving the system we have:
x = 230
y = 145
Answer:
Dave: 145 Allan: 230
Answer:
D. 10.91 square centimeters
Step-by-step explanation:
Area of a sector of a circle = 
where 
radius (r) = half of diameter = 10/2 = 5 cm
Area = 
= 10.91 
8 * 4 = 32 which is a number in between 30 and 40
So the newspaper has 4 sections.
