Answer:
180 miles
Step-by-step explanation:
Step one:
capacity of tank= 18.5gallons
vehicle averages 666 miles per tank.
Hence, the vehicle can travel 666 miles on 18.5 gallons
Required
The distance covered on 5 gallons
Step two:
vehicle can travel 666 miles on 18.5 gallons
the vehicle will go x miles on 5 gallons
cross multiply we have
5*666= 18.5*x
3330=18.5x
divide both sides by 18.5
x= 3330/18.5
x=180 miles
Let us assume $x is deposit at 2.5% interest.
At the rate 4.5% deposited amount is twice of the amount deposited at 2.5%.
Therefore, at the rate 4.5% deposited amount = $2x.
Total interest earned by both different deposited amount at the rate 2.5% and at the rate 4.5% = $1150.
We can setup an eqation now,
Interest earned on $x at 2.5% + interest earned on $2 at 4.5% = $1150.
2.5% of x + 4.5% of 2x = 1150
Percentage could be written in decimals by dividing by 100.
Therefore, 2.5% = 2.5 /100= 0.025 and 4.5% = 4.5/100 = 0.045.
We could rewrite above equation as,
0.025*x + 0.045 * 2x = 1150
0.025x + 0.09x =1150
Adding 0.025x + 0.09x, we get 0.115x.
So, 0.115x=1150.
Dividing both sides by 0.115.
0.115x/0.115=1150/0.115.
x= $1000.
2x= 2* 1000= $2000
Therefore,
$1000 deposited at 2.5% and $2000 deposited at 4.5%.
Answer:
x = -7/40
, y = -11/20
Step-by-step explanation:
Solve the following system:
{12 x - 2 y = -1 | (equation 1)
4 x + 6 y = -4 | (equation 2)
Subtract 1/3 × (equation 1) from equation 2:
{12 x - 2 y = -1 | (equation 1)
0 x+(20 y)/3 = (-11)/3 | (equation 2)
Multiply equation 2 by 3:
{12 x - 2 y = -1 | (equation 1)
0 x+20 y = -11 | (equation 2)
Divide equation 2 by 20:
{12 x - 2 y = -1 | (equation 1)
0 x+y = (-11)/20 | (equation 2)
Add 2 × (equation 2) to equation 1:
{12 x+0 y = (-21)/10 | (equation 1)
0 x+y = -11/20 | (equation 2)
Divide equation 1 by 12:
{x+0 y = (-7)/40 | (equation 1)
0 x+y = -11/20 | (equation 2)
Collect results:
Answer: {x = -7/40
, y = -11/20
Well I don't know if i'm answering the question, but 30 workers surveyed were satisfied with the benefits they received from the employers because 300 multiplied by .10 is 30. Hope my answer is useful.
