Answer:
10
Step-by-step explanation:
If we notice, the decrease in payment after 3 and 5 months, it is a multiple of 150.
So, the equation that models balance b after m months is:
b = 1800 - 150m
Here, - 150 is the slope and it indicates the amount being decreased every month.
Answer:
50%
Step-by-step explanation:
You could make an equation:
200+(x/100*200)=300
x/100*200=100
200x/100=100
200x=10000
x=50
OR you could use this formula:
Percent Change = (Amount of Change/Beginning Amount) *100
Percent Change = (300-200/200)*100
Percent Change=1/2*100
Percent change = 50%
hope this helps!
Answer:
Step-by-step explanation:
sum of angle of triangle is 180 degree
5x+8x+50degree =180 degree
13x= 180-50
13x= 130
x= 130/13
x=10
5x= 5*10=50degree
8x= 8*10 =80degree
- 3(15m - 4)/ 40 negative should be outside of the fraction
