From the expression 2f + 5(8-f), we know that Karla caught f purple dot fish, and (8-f) green dot fish, because green dot fish gives 5 points.
2f -points for the purple dot fish, f is a number of the purple dot fish.
5(8-f) - points for the green dot fish, (8-f) is a number of the green dot fish.
So,
altogether she made 8 attempts.
One attempt cost 50 cents,
8 attempts cost 8*50=400 cents = $ 4.
Answer is B. 4 (dollars).
Answer:
200
Step-by-step explanation:
Let number of tickets sold before game be x while those at the gate be y
Total tickets sold are 600 hence x+y=600
Cost of tickets
Total amount collected is $700 hence
x+1.5y=700
x+y=600
x+1.5y=700
Subtracting equation 1 and 2
0.5y=100 hence y=200
OOH USE YOUR BRAiN AND THINK :D
Answer:
Step-by-step explanation:
Given
Points: (0,3) and (-4,-1)
Formula
x = 0 to find the y intercept
m = (y2 - y1)/(x2 - x1)
Solution
y2 = 3
y1 = - 1
x2 = 0
x1 = - 4
m = (3 - -1)/(0 - - 4)
m = 4/4
m = 1
You have y = mx + b so m = 1
the general equation becomes y = x + b
Use point (0,-4)
y = x + b
- 4 = 0 + b
b = - 4
y = x - 4
Answer
x=50+9
x=59
x=80/10
x=8
