Step-by-step explanation:
Answer:
Total = 686000 meters for 10 weeks 7 days a week.
Step-by-step explanation:
Let's solve this by doing the increase on just 1 training day per week. Then we can find the grand total for 7 days a week by multiplying by 7
a = 8000
n = 10
d = 400
Sum = (a + L)*n/2
- L = a + (n - 1)*d
- L = 8000 + (10 - 1)*400
- L = 8000 + 9*400
- L = 8000 + 3600
- L = 11600 meters
Sum = (8000 + 11600)*10/2
Sum = 19600 * 10/2
Sum = 98000 meters.
This total represents 1 training day a week.
The total amount is 7 times this figure.
Total = 7 * 98000 = 686 000 meters.
Set the equation to look like
20/100 = x/25
Then multiply to get
500 = 100x
500/100 = x
5 = x
Therefore James spent 5 dollars initially on ingredients.
Answer:
y+6=3/2(x+9)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(6-(-6))/(-1-(-9))
m=(6+6)/(-1+9)
m=12/8
simplify
m=3/2
y-(-6)=3/2(x-(-9))
y+6=3/2(x+9)
You could wash 75 cars at this rate because 45/3 equals 15. You would multiply 5 by 15 and get 75.
