Not sure what this question is asking but for the hourly rate, the answer is $20.
Step-by-step explanation:
You can write an equation as 20x=400.
Simply solve it by dividing each side by 20 to find the hourly rate in dollars per hour.
You get x=20 as your answer so 20 dollars per hour!
Hope this helps! :)
Top equation, minus 10 both sides to get
3x-2y=-10
bottom equation, minus 4x both sides
5y-4x=8
-4x+5y=8
now elimiate y's
multiply top equation by 5 and bottom equaiton by 2 and add them together
15x-10y=-50
<u>-8x+10y=16 +</u>
7x+0y=-34
7x=-34
divide both sides by 7
x=-34/7
sub back
3x-2y=-10
3(-34/7)-2y=-10
(-102/7)-2y=-10
add (102/7) to both sides
-2y=-10+(102/7)
-2y=(-70/7)+(102/7)
-2y=32/7
divide both sides by -2, or times both sides by -1/2
y=-32/14
y=-16/7
(x,y)
(-34/7,-16/7)
Answer:
Step-by-step explanation:
We would apply the formula for determining simple interest which is expressed as
I = PRT/100
Where
I represents interest paid on the amount invested.
P represents the principal or amount invested.
R represents interest rate
T represents the duration of the investment in years.
From the information given,
P = 5800
R = 7.5
T = 1 year
I = (5800 × 7.5 × 1)/100 = $435
Therefore,
The increase in amount is $435
The Year-end amount is
5800 + 435 = $6235
