Answer:
r=2
Step-by-step explanation:
2r=d
now,
2r=4 units
or, r =4/2
so, r=2
The answer is 5.1 if you're looking for s all the work is in the picture
The answer is x<6 because you have to divide 3 on both side
Answer:
3x = 50 - 10y
Step-by-step explanation:
Here, x represents the number of 3 lb weights and y represents the number of 10 lb weights,
So, total weight of 3 lb weights = 3x
And, the weight of 10 lb weights = 10y
Total weight of all his weights = 3x + 10y
According to the question,
Total weight = 50 lb,
⇒ 3x + 10y = 50
Or 3x = 50 - 10y
Which is the required equation.
Second option is correct.
Answer:
$5
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year,
putting time into years for simplicity,
3 months ÷ 12 months/year = 0.25 years,
then, solving our equation
I = 500 × 0.04 × 0.25 = 5
I = $ 5.00
The simple interest accumulated
on a principal of $ 500.00
at a rate of 4% per year
for 0.25 years (3 months) is $ 5.00.
