Answer:
D. $680
Step By Step Explanation:
100 pages are typed. Each page coast $5 to type.
100 x 5 = 500
40 pages are revised once. It costs $3 to revise a page once.
40 x 3 = 120
10 pages are revised twice. It costs $3 to revise a page once so it will cost $6 to revise it twice
10 x 6 = 60
To find the total cost we add all the amounts together
500 + 120 + 60 = 680
The final answer is $680

Step-by-step explanation:
The starting point of 0 has a value of 3. The common difference of 2 is added at each step increse in n.
n f(n)
0 3
1 5
2 7
3 9
4 11
The can be modeled by the equation y = 2x+3
Answer:
(9,36)
Step-by-step explanation:
Substitute the 4x for the y in second equation.
Basically setting them equal to each other because the both have 'y='
4x = 8x - 36
-4x = -36 (subtract 8x from both sides)
x = 9 (divide by -4, both sides)
y = 4(9) (Substitute the x value into first equation)
y = 36
Bananas to apples = 12:8
= 12/8
= 3/2
Answer:
x = 3
Step-by-step explanation:
Perimeter of the rectangle = 2(l + b)
where l is the length of the rectangle and
b is the breadth of the rectangle.
Here, the perimeter is given to be 18 meters.
And l = 2x m and b = x m
⇒ 18 = 2(2x + x) = 2(3x) = 6x
⇒ x = 3
∴ The value of x is 3 m.
