Let the cost of one book= x cents
Let the money john have= y cents
According to the question,
45x=y ...eq(1)
(45+5)(x-5)=y
50(x-5)=y
50x-250=y ...eq(2)
On subtracting (1) from (2).
(50x-250)-45x=y-y
5x-250=0
x=250/5
x=50
Thus, cost of each book is 50 cents and john has 2250 cents.
Hope it helps.
Don't feel shy in saying thx if it helps.
Answer: The slope is 0
Step-by-step explanation:
The slope is the difference between the y coordinates divided by the difference between the x coordinates.
Y: 9 - 9 = 0
x: -7-2 = -9
0/-9= 0
Answer: 8 centimeters
Step-by-step explanation: To find the radius of the circle, remember that the formula for the area of a circle is πr² and since we're given that the area of our circle is 64π, we can set up the equation 64π = πr².
To solve for <em>r</em>, we first divide both sides of the equation by π.
On the left side, the π's cancel and we're left with 64 and on the right side, the π's cancel and we're left with r².
So we have 64 = r².
Next, we take the square root of both sides to get 8 = r.
So the radius of our circle is 8 centimeters.
Answer:
y=4/3x-1/3
Step-by-step explanation:
m=y2-y1/x2-x1
fill in the two points for the y's and the x's
then proceed to y = mx+b
Where:
m is the slope, and
b is the y-intercept
then you solve and <u>bam</u>!
