Answer:
y=3x
Step-by-step explanation:
If y is the total distance from the shore and it increases by 3 miles every hour, then by plugging in the amount of hours that have passed into x we will find the distance they have traveled. For example, if they have been out for 5 hours then you would do y=3(5) which would be 15 miles from the shore.
Hope this helps :)
I think you use
xamount(1-.8)
.8 being 80% as a decimal.
1 being 100%
so .2 or 20% remaining multiplied by whatever amount.
Let x be the amount invested at 7% and y the amount invested at 6%
We know that the yearly interest earned = 0.07(x) and 0.06(y)
x+y =4500
0.07x +0.06 y =290
Solving the equations will give , x = $2,000 and y=$2,500
Answer: length = 75 cm
Step-by-step explanation:
61 x 2 = 122
272-122= 150
150 divided by 2 = 75
check: 75+61= 136
136 x 2 = 272
hope this helps!
