Answer:
when x=6, y=30
when x=7.5, y=37.5
Step-by-step explanation:
Just plug in the value of x into the equation y=5x
so when x=6, the equation will be y=5(6). In this case y=30
when x =7.5, the equation will be y=5(7.5). So y=37.5
A.
Getting an exact number for gravel is difficult because it spills and the ground is not usually perfectly level. Thus it would be okay to estimate the amount needed.
<span>Let’s assume the number of problems as P
Student did his homework = (3/5) P + 8
Father did the homework = (1/5) P + 7
So the sum of the both equations is equal to P
=> (3/5) P + 8 + (1/5) P + 7 = P
=> (4/5) P + 15 = P
=> 4P + 75 = 5P
=> P = 75
Problems they solve together are 75 problems.</span>
Answer:
$734.40
Step-by-step explanation:
y=9,000(1.04)^t is our equation for this.
The 9,000 is the starting amount.
1.04 is the 4% since 4% is 4/100 which equals 0.04, then we add 1 to that since it's increasing in value.
y represents our output.
t represents time (in years for this equation)
Since they give us the amount of years since he deposited the $9,000, we put the number they gave us (2 years) into the equation, replacing t.
y=9,000(1.04)^2
Put the right side into a calculator and it gives you 9734.4.
That's the total amount he has now, so to find how much he earned we subtract the starting amount (9000).
734.4.
Edward earned $734.40.

The answer is B
Step-by-step explanation:
2021 - 1962 =59
59-13=46
2021-46=1975
Then 7+3=10
